I set up the Goiter to do some short (50-100k per day) self-supported 1- or 2-day tours.
140mm cranks provide a good balance between torque and speed for my purpose.
The bag is a Jandd Mountain Wedge 3… 7.47 liter (456 cubic inch) capacity. It provides as much as volume as you’ll find in many rack bags. It fits well within the confines of the space available, and it keeps the mass of my cargo close to the seat tube…compared to a rack/trunk combo. I utilized a length-adjustable tandem stoker stem to mount it. The boom below the bag acts as a stabalizer and potential fender/accessory mount. Heavy items will go in the Jandd bag: toiletries, tools, spare tube, first aid, food, alcohol stove, fuel, ti cook pot, eating utensils, tea light lantern with 3 tea lights (enough for 12+ hours of light), LED flashlight, paperback book, notebook and pen, firestarting stuff, misc. Most of my gear is ultralight and compact, so it will fit easily in the Jandd bag or my backpack.
Lighter bulky items (down sleeping bag, sleeping pad, tent or hammock, clothes) will go in an ultralight (255 gram) Dana Designs backpack. The total weight on my back should stay under 3.6 kg (8 lbs). The backpack has a pouch for my 3 liter (100 oz) water bladder. I’ll fill it when I get close to my campsite.
I can still mount a Magura rim brake system, if I remove the upper bottle cage to make room for the brake lever. If necessary, I can mount both bottle cages on a separate forward-facing boom that clamps to the seat tube (like the one that anchors the bottom of the Jandd bag). I won’t need the brake on my next outing…my route utilizes a lot of mellow rails-to-trails bike paths, but I’ll probably remount it in the future.
I was entertaining the thought of using a GB4 handle on my Miyata seat. But, I figured it might be nice to try some different handle positions, and I like my Velo saddle better than the Miyata. So, I kept the Velo saddle on and made a modular handle system. I can adjust the barend positions easily by changing barend tilt, stem position, stem length, and stem angle. It’s not as tough as a GB4, and I’m sure it would be damaged in a crash. I’ll just have to concentrate on not crashing. Eventually, I’ll get my position dialed in and braze together a new handle out of cromoly…replicating my desired position. The longer handle (how it’s pictured) lets me tuck my arms in and get low in a headwind.
I’ve ridden around Minneapolis with my rig loaded up, so I could check out the riding characteristics before heading out on an overnight. It seems fine. As you’d imagine, it takes a little more work to turn, accelerate, and decelerate, but it’s very rideable. The 3.7" tires allow for a plush ride. I prefer my air cushion next to the ground vs. on top of the saddle. I’m heading out to the western 'burbs of Minneapolis (50km out, 50km back) in a couple of weeks to test the system. I’ll have more feedback then.
