"RatRace"

Preliminary pics of my latest build "RatRace". Rear wheel will be strong spoked w/ Sturmey Archer 8spd disc mount hub and Sturmey cranks for 8 spd hub. I'll be purchasing an engine drive sprocket from Andy @ king's. I'll run KMC Kool Chain both sides no tensioner. I'm going w/ the dual pull Brake lever. All w/ a nice vintage "patina"!

I'm using a small skateboard wheel as a tensioner, it would work great on your tensioner set up. They have 2 high quality sealed bearings, have a larger diameter and are made of urethane so they absorb a little shock and clatter.

Cool

Odd placement of the tank but I kinda like it.

Ok so heres the "finished" product w/ beefier tensioner, nice straight chainlines, 8 speeds and finally a sealed gas tank; maybe ride it to work in the mornin'.
I'm very happy w/ this build. The bike feels really solid; brakes feel plenty strong. Geared ets mid 30's right now. :1eye:

Update. The Sturmey Archer 8 speed hub doesn't respond well to being motor driven on the disc mount. I'm guessing the clutches inside the hub don't respond well to the pulses of the motor. I've not sold any of these for m/b use and won't be! I'm very happy w/ their front hubs, though, and they did warranty my 8 speed so I'm very happy w/ Sturmey Archer o/a!
Looks like I'll be mounting a disc mount cassette hub and derailer in the coming week!

Did the disk mount fail? Or did the internal gear not shift right due to vibration?

The disc mount is plenty stout. It just stopped working properly; shifted but didn't work in gear (intermitantly) and became unadjustable. All w/in 15 mi or so. Quite honestly could've been a defective hub but I don't want to keep trying. So I'm selling the replacement on fleabay.

This is a very nice hub for bicycling and lends itself fantastically to alternate gear ratios, just doesn't seem to like being motor driven.

One of the main scopes of my company is to provide components and service that add to the reliability, safety, and comfort of motorbicycles. This didn't make a good 1st impression so I'll go back to what I know is reliable to finish this build and continue to research other alternatives in the future.

I quite like that "mission statement", and would wish that far more businesses took such a customer friendly approach.

I wish you every success.
