The cranks, headset, chain and pedals will go on this weekend. I should save a few more grames by the time I am done.

My bike feels nice and the tires really roll pretty fast and well for 2.0s.

Hopefully the kid will love riding with daddy and I know have a commuting specific ride instead of sawping wheels on my roadie. Also great for Starbucks runs when I need a fix...:D

You know that crossed my mind....

and that was my original idea when buying a bike, but I have no idea on SS gearing. I guess I can figure out gearing once the kid is loaded and I can see what gears would be right.

I guees it would require a hub conversion kit, a Surley Singletor (or similar device) and the rear and front rings?

I will ask in the SS forum if I decide....

wow !

Hey DirtBoy !
It almost looks like a race touring bike, seriously it looks fast :) .

That's always fun to experiment weightweenieness with unorthodox kinds of bikes.

Have fun !

I'm impressed you were able to get a threadless stem to work on a threaded steerer. :D

I can't wait to see what you do to lighten the Chariot.

LOL! Its new technology that called....

a Quill Adpater :D

"STEM: FSA XC-170 120mm w/ threadless stem adapter"

Here is what I used: Nashbar Threadless Stem Adaptor

With this adaptor you can keep your threaded fork and headset and have a better choice of threadless stems. The top portion accepts1 1/8" stems only.



I plan a mix of Aluminum and Ti bolts on the trailer and of course Stan's NoTubes System or DT Swiss/Eclipse Tubeless Kits. To bad the fast freds don't come in 20" size :p.

Well they stop fine, but hard to adjust...

I keep getting minor drag. i don't know if ots the brakes or the rotors.
This bike is just used for cummuting and now hauling the kid around so the power is fine.

Here is a new updated and lighter bike picture.

Thanks, next week is goig to be...

A Single Speed with a 46/16T gearing. then I am getting a rigid fork in 2-3 weeks and I am done! Should be near 26lbs when I am done.

The Schwalbe Supermotos kick some major ass on the road!! I run them at 34/38psi and they still roll very easy and fast!!
