Seeing how I can never leave any of my bikes alone for very long without tweaking them in some way or another, my latest energy has been focused on simplifying the drivetrain on my Waltworks. I didn't want just one gear, since I'm kind of over the SS thing, so I decided 2 or 3 gears would suffice. Initially, my idea was to run a double up front and a single cog in the back using a Paul's Melvin, but I ditched that after meeting Jeff Jones at Sea Otter and seeing his 2x4 drivetrain. Took an XTR medium cage RD, and the 15, 21, and 23 cogs from an old Ultegra cassette, and slid them onto my Bonty cassette SS hub. I tried adding a 4th cog, but that left no threads for the lockring, so 3 cogs it was. With a 34 ring up front, that means my primary gear will be 34/21, which is good for my area, then I'll have 34/23 if I need a little help on the steeper stuff, and 34/15 for cruising the flats/downhills. It's all controlled by an Ultegra barcon set in friction mode on a Paul's Thumbie.

Since I last posted pictures of this bike, I've switched to an H-Bar also. Having ridden a flat bar on my Dos Niner for the past couple months while my WW has been undergoing drivetrain surgery, I'm happy to be back on the H-Bar.

The plan is to take it out for a good test ride tomorrow to make sure it all stays tight. I've set the limit screws on the RD so the chain won't fall off into the frame, but I don't think I can get enough adjustment to keep the it from going off towards the spokes. Luckily there is enough space between the inner cog and the spokes that if I shift too far, I won't damage my spokes. Just gotta pay attention!!
Any questions, lemme know...
