Bike camp & birthday wheels

Flying on her new Specialized Myka. 
Though already half over, July has been eventful, encapsulating bike camp in Waterton Canyon and a double digit birthday. For good or bad, bike camp happened during an especially rainy week in an abnormally rainy year, so big sister is now a seasoned veteran mud rider.

In the midst of bike camp, she made the jump from 24-inch to 26-inch wheels, via a slightly early birthday bike. The 13-inch frame of a 2012 Specialized Myka Sport is the perfect entry to the world of high quality, big people mountain bike parts. After I performed a quick rebuild, the Myka now features a 2x9 Deore drivetrain, Avid BB5 disc brakes, wide 26" tires, and a Rockshox Recon Gold 100mm suspension fork.
The girls each on new-to-them bikes. 
I decided after she toughed out the first few rain soaked days of bike camp without complaint, that she was due for the bigger bike. Her old bike, a Specialized Hotrock 24" has served us well, but its gearing was not ideal for conditions, and had begun to look a bit small in proportion to her rapidly growing limbs.


Soaked but smiling after the first epic ride of camp. 

She was particularly proud of how muddy her legs were. 

I sewed a tiny framepack to help with the load. 

The Myka will need a larger framepack. 

Friend to amphibians. 



Skipping rocks is an important skill to master. 

The Cateye logged 56 miles of trail over five days. She said she could have gone a lot farther. 

After she figured out that the bigger bike could do things that her old bike couldn't, it was an instant hit. It didn't hurt its popularity that Lael also rides a black Specialized bike. She was especially amazed at the ability of the Rockshox Recon to both smoothe the trail and improve control in a way the mostly ornamental RST fork on her Hotrock simply can't do. In all, she's faster and more confident on the Myka, though there is still much to learn.



Packing material shenanigans.

There's always room for one more: DIY hanging bike storage

Lots of bikes don't necessarily have to take up lots of space.
Be forewarned, technical bike nerdery ahead. If you choose to follow the instructions, any outcome is your own risk and responsibility. Please don't attempt any construction if you are not confident in your skills.

Imagine that, one way or another, you've found yourself in a situation where you own more bikes than all your neighbors combined. Or, perhaps, you have a more culturally acceptable quantity of bikes (maybe shockingly as few a one), yet still find that you have more bikes than space for bikes. Alternately consider the not so farfetched possibility that you need to spatially justify a bike acquisition in order to maintain domestic tranquility.

In each of these cases, a better plan for bike parking could improve your life. Fortunately, a good solution is both cheap and easy, using utility hooks available at any hardware store, a few long screws, and some 2x4 or 2x6 scrap wood. You'll also need a drill, a saw, and some other common tools as needed.
The larger type hook on the left allows passage of fatter tires more readily, has a larger diameter steel core, and has a tougher coating than the standard type hook on the right. Bigger is better.
The above materials are combined into a bike hanging structure from which one or more bikes are hung from the wall by one wheel, thusly:
Alternating bars up/bars down for orderly and efficient bike hoarding.
The design of your bike hanging rig depends on a few factors:  1) the available wall space 2) the number of bikes you'd like to hang 3) the length of wood available.

The first step is to measure the length of wall where you'd like to hang your bikes. You'll need at least 20 linear inches of wall for every bike you want to hang. It may require even more space if your bikes have especially wide handlebars, which is the main determining measure. The minimum height of the wall is the length of your bike plus about 8+ inches, so as to keep the bottom tire off the floor when hung.

Next, is to measure and drill holes in the wood in which the utility hooks will be installed. In my experience, a distance between holes of approximately 18 to 20 inches works well to maximize used space while maintaining relative ease of bike removal when hanging bikes in an alternating bars up/bars down pattern. Therefore, the length of wood you'll need can be calculated as in the following example for a 3-bike rig with hooks spaced 20" apart:

  • 3" (edge to first hook) 
  • + 20" (first hook to second hook) 
  • + 20" (second hook to third hook) 
  • + 3" (third hook to edge) 
  • = 46" board length 

Remember, the linear length of wall you'll need is longer than the board length, to accommodate the handlebars of the outer bikes. In this example, the wall will need to be at least 60 linear inches.
I used three 3 1/2" deck screws anchored in a wall stud to attach the 2x6 board to the wall. The more studs, the better, as they say.
Drill the first hole into the centerline of the wood, three inches inboard from the edge of the wood. Again, be sure to allow for the distance necessary for the bike's handlebar to clear the neighboring wall. Note that it is important to drill the holes for the utility hooks angled downward about 15 to 20 degrees to relieve stress on them, as the weight of the bike pulls them down. If installed perpendicular to the wall, the utility hooks will bend downward.
Note the hook angled downward.

I installed these hooks about 18.5" apart on center, in the days before the wide bars that I now so enjoy. I'd lean more toward 20" apart if I were to rebuild.
Subsequent holes should be approximately 18 to 20 inches apart. Once all the hook holes are drilled, it's time to mount the boards to the wall. I use 3 1/2" deck screws in every stud along the length of the board. Be sure that the screws are solidly in studs, as it wouldn't be much fun to have your bike hanging rig and bikes all collapse on the floor. It is beneficial to have a stud located near each end of the board. Use a level to ensure the board is parallel to the floor, and be sure to have it high enough so your longest bike's rear tire clears the floor. The utility hooks can be installed either before or after the board is screwed to the wall.

Two 29ers with 750+ mm wide handlebars are a little snug on hooks 18.5" on center. I may respace the hooks to be a bit further apart.
In the case that you've got fatbikes to deal with, such beasts still work fine for hanging. However, a standard utility hook won't work. Many hardware stores carry a variety of hooks that can successfully grasp a fatbike wheel. I found a heavy duty hook that is about 5" wide that fits the Surly Darryl/Larry combo on my Pugsley.
Pugsley peacefully coexisting with my 30 year-old Miyata. Wide bars on both.

Fatties fit fine.
Just about any bike can be hung using this kind of rig, so long as the bike isn't so heavy that it will pull the hook out of the board. To date, I've hung bikes up to about 60 pounds in weight, with no problem other than hefting a wheel up to the hook.
These hefty old Schwinns hang just fine.
So there you go. I can't claim that this is the definitive method for storing bikes, but I don't know of any other way that is as cheap, easy, or efficient. Bikes hung in this manner remain simple to retrieve for a ride, they won't fall over and get scratched against each other, and the positive aura emitted from a wall of bikes embiggens any aspiring bike barn. Such a rig can also keep an overly abundant bike herd orderly enough so as to support domestic tranquility, though your mileage may vary.

Quick DIY top tube frame pack

The pack took about 90 minutes to make in total, from measuring the frame to strapping it on.
After finding out how convenient frame packs are for carrying things, I had been wanting to construct packs specifically sized to other bikes. To this end, I put together a simple top tube frame pack, using materials that I had on hand for this first tester example. The pack is made of about 1/2 yard of cordura pack cloth that's been in my sewing kit for 20+ years, an old steel YKK 19" zipper, various scraps of Velcro, and some 100% polyester upholstery thread. I didn't produce detailed instructions, but if you are interested in building a similar pack, it's a simple process if you have at least proficient sewing skills. The design is essentially a box, shaped to fit the inside of the frame, with a zipper installed on one side.

Cardboard template for the frame pack.
To begin, I took a piece of cardboard, a pen, and a utility knife, and constructed a template of the inside of the front triangle of my 2002 58 cm Surly Cross-Check. The cardboard template guides the shape for each side of the pack. I made sure to mark the locations of cable stops, housing, bottle mounts, etc. so that the Velcro straps cleared them. To connect the two sides of the pack, I used strips 3" wide. On each piece of fabric cut for the project, I added .25" all the way around to account for the seam edge. I also constructed a flap over the zipper, to help protect it from rain, etc., though this pack is by no means waterproof.

The pack easily holds my trusty Stanley cook pot with enclosed pop can alcohol stove and fuel, among other items.  It's big enough to be useful for a picnic, a camp outing, or a small grocery trip.
The pack turned out fairly well, and fits the frame exactly as intended. The design worked well for fabrication, though I won't use the same materials for the next one. The cordura material is quite sturdy, though it's not nearly as light or water resistent as similarly sturdy modern materials, such as Dimension Polyant X-Pac. The steel zipper works well enough, but it's heavy, and its action is not as smooth as plastic. A modern water resistant plastic zipper will be part of the next pack I make. In the end, I learned a bit about how I'll make subsequent packs.

The pack is not wide enough to get in the way of riding.

The right side has no zipper.

The left side has a zipper. Why the left? I'm left handed. Make your own pack how you like.

With the pack installed, there's still plenty of room for water bottles below.

Bike camping prep

It's a big fat Pug: at 58.5 lbs loaded, minus food, some water, and a few odds and ends. 
I've been gearing up to do some bikepacking since sometime last year. My philosophy has been to do it on the cheap when feasible, as I don't have the time or resources to commit myself to a load of camping of any sort. By way of checking out what other people use for equipment and compiling a spreadsheet tailored to my own needs, I've been able to ascertain what I have, what I need, and what I can do without. Initially the big gaps were lightweight versions of a tent, a sleeping bag, and a sleeping mat. That's of course apart from the means to carry all my junk.

Selling a few bikes recently and putting the proceeds into an REI sale, I was able to acquire a Kelty Salida 2 tent, a Sierra Designs Zissou (as in Steve) 23 long down bag, and a REI Flash long insulated air mattress. Coupled with the set of Revelate Designs framepack, Viscacha seat bag, and Sweet Roll handlebar bag (via Gypsy), that I've acquired over time, most of the big gaps have been filled.

About as light as most Big Agnes SL series tents, at about half the price.
Spacious for one, plenty for two inside. 
I had originally planned to go with any one of several Big Agnes tents, mostly on their reputation of quality from more seasoned bikepackers. I particularly like the Big Agnes Slater UL2+ and may one day go that route, but for now, in the balance of economics versus how many nights I'm likely to be able to camp to justify a fancier tent, economics won out. There is a bit of a weight penalty, but a pound or so is something that I can live with in the short term.

The Salida 2 itself has a decent reputation as a good value light weight tent, albeit with fewer bells and whistles. The great REI return policy provides a bit of insurance either way. I gave the new items a test with a back yard campout. All seem to be more than good enough for my purposes, and considerably better than my 10 to 20+ year-old, much heavier and bulkier equipment.

As for cooking equipment, I've gone the ultra cheap route. I've now built a few Penny stoves and found them to be a terrific design; nearly free of cost, extremely low mass, using easy to source fuel, and with good fuel consumption. In the same spirit, I sourced an on-sale Stanley 700ml covered pot cook set for $15. There are plenty of lighter pots out there, but it isn't too heavy and it's just about the right size.

I have Lexan utensils, but prefer something that is more heat resistant. I had some cheap, and therefore light, stainless steel utensils in my car camping kit. The only problem was the fork was too long to fit in the Stanley pot. A couple of minutes with a hacksaw and a grinder, and the problem is solved.

Step 1: Hack a bit off the cheap stainless fork...
... so that it's about the same length as the spoon. 
Step 2: Grind a nice curve that can serve double duty as a jelly spreader or tire lever.
Step 3: Beam a little about how this combo is more hobo-chic than a titanium spork, even if it weighs a bit more.
I packed everything up in the bags on the Pugsley and took a little ride with Scout. The whole setup is still missing some food and water, but all of what I'll need for an overnighter is about 87.5% there. The bike is heavy, and it certainly feels somewhat heavy, but is definitely not unrideable. It's just a matter of getting a feel for it in the context of what I hope to do with it, and dialing it in a little more. I'll likely be pushing it up steep hills, but there's a likelihood that I'd be doing that unladen anyway. In all, it's now an all-terrain, two-wheeled RV, and RVs aren't renown for speed.

Hard to tell from this phone pic, but that's a Boeing B-17 Flying Fortress going over my neighborhood. Four big radial engines create a nice rumble.
It rolls pretty well loaded.

Part 2: Home-built Xtracycle/Big Dummy seat

Seatbelt magic resides in the holes.
We left off last time with a more-or-less finished deck seat assembly. I used the seat as it appeared in that last post for over four years without an integrated seatbelt system. Instead, I used a length of one-inch wide utility webbing and an adjustable buckle purchased from REI; something very similar to, but not quite exactly like this. I ran the webbing under both v-racks (over the rear fender), with each end of the webbing coming up behind each side panel of the seat deck assembly, then over her lap with the buckle in the middle of her lap. My eldest daughter was three years old when she started riding in the seat, and this configuration worked fine for her at that age. Yet, I always thought there was room for improvement.

A piqued interest of my youngest daughter in riding the Big Dummy recently hastened seatbelt improvements. She is now about 15 months old, and although she has enjoyed riding in our old Burley trailer, she wants to do what the big people are doing and has very recently become very energized about riding on the Dummy. She did a few rides with the old seatbelt system, but it seemed that a five-point harness was in order.

I didn't want for screw heads or other hardware protrusions to stick out of the areas where her body would be in contact, so I devised the following system using easy-to-source webbing and Fastex-type fasteners. There is perhaps some detail missing below, but this is a new development and still in the process of being honed. As I get it dialed in, I'll post more photos.

Here we go. I used a one-inch diameter drill bit to make holes through which I inserted 3/4-inch webbing. Note that I would have preferred to use one-inch webbing, but 3/4 was what I had on hand. depending on how things work out, I may reconfigure the webbing, which shouldn't be a big deal. In any case, the procedure follows.
Pilot holes first. For the shoulder straps, I drilled two holes six inches apart on center, centered across the backrest. Each hole is 2 1/2 inches down from the top of the backrest. 
After drilling the pilot holes, I drilled with the 1" bit part of the way through the back...
...and the rest of the way through the front so as not to rip up either the front or back face of the wood upon exit.
For the seat belt, I located the hole center about 2 1/2 inches above the deck surface, centered laterally on the side panel. Same drilling procedure as above. 
After the holes were drilled, I sanded and smoothed their edges to reduce the potential for wear on the straps. Next came installation of the straps. I used some 3/4-inch nylon webbing that conveniently already had buckles installed, with one side adjustable and the other side fixed. Three sets of webbing and buckles are needed, as are 2 Fastex-type three-bar sliders, 1 D-ring, and 1 snaphook. First the seatbelt.
Sorry for the photo that doesn't quite focus on the seatbelt, but hopefully the threading pattern is clear. The goal is a snug fit at the passenger's hips, just below the iliac crest; not at the waist. A webbing/buckle combo is shown in the foreground. 
This is just a reference photo, showing a three-bar slider. These are used to attach the webbing with the fixed side of the buckle to the shoulder strap holes. I made sure to configure any non-smooth or hardware side of the strapping system away from body contact with the passenger.
The anchor strap for connecting the shoulder harness to the deck passes between the legs of the passenger. It's necessary for it to be quite secure. I could have opted to use a hole-based system as with the other straps, but instead I used a bolt. Based on some measurements and test fittings, I drilled a hole 6 1/2 inches back from the nose of the deck. I fastened stainless steel hardware, in this order from the top down: bolt, flat washer, webbing (two ends of a simple loop doubled over with the d-ring at the apex of the loop, and with holes pre-drilled for the bolt), wooden deck, flat washer, lock washer, nut. This will make more sense with the following photos.
Drilling the anchor bolt hole. Anchor bolt is in the foreground.
Anchor strap installed. Note the position of the d-ring. It's easiest to drill the webbing when it is sandwiched between two scrap pieces of wood. Making the anchor strap adjustable might have been nice, but is not entirely necessary.
Underside of the anchor bolt.
I measured and cut a slit in the foam pad through which to work the anchor strap.
Everything in place, but yet to be adjusted. The Fastex snaphook clips to the d-ring, and has a length of webbing running through it. Each end of this piece of webbing has the adjustable side of each of the the two shoulder strap buckles. The two three-bar sliders are at the top of the backrest, holding the shoulder straps to the backrest. 
A view from the back. Note the back of the seatbelt runs behind the seat, and the shoulder straps loop through the backrest. The goal of no hardware protruding into the passenger space has been met.
The first ride with the new strap system. It apparently gets a thumbs up. Note that I left the straps long for adjustment. Once they're dialed, I'll trim them. The handlebar holds a bell and a bottle cage; both well appreciated by diminutive co-pilots.
Hopefully, this presentation has made some sense and is not too difficult to follow. I can affirm that there will be at least one more installment of this series, with some more detail and updates regarding the strap system, among other things.

If this all seems like a lot of effort, well, it is to a degree. However, I personally consider the ability to safely carry passengers the defining element of my Big Dummy experience. Carrying kids and cargo has radically reshaped my biking life and made for some of the best times I've had on two wheels.
