Manufact by Rotor. Rotor cranks with Q rings.

 

Oval type chain ring. Think they are similar to the old Bio Pace of Shimano the used back in 90's.

 

Burry Stander, Kevin Evans and those chaps use them, worth to have alook at.

Wow, that's hot, nice bike NSBB!

 

How's your chain length, looks like you could probably lose an extra link or two?

Thanks V :)

 

You remind me that I should have done it ..... should I just start by taking out 2 and then see how it goes or is there a way to measure the 'ideal' length?

Took a spin through Rietvlei this afternoon ...... the good :) I can ride my 'normal' loop with those gears. Not easy but didn't have to step off even once! The bad :( - no go without a chainguide, on any 'bumpy' down sections where you not pedalling the chain comes off. Always to the outside for some reason.

 

I have 'spaced' the guide I got from Thug so will try it out again tomorrow if I get a chance .... no way I can get it with no chainrub (either at the top or bottom). Decided to go with very little rub in the 11 since I spend a lot less time in the 34.

Hold the phone,

a 1x10 26" is faster than a 2x10 29er.

Not possible, can not be, say it aint so. :mellow:
