Is the BB length of 113mm for 145mm drop out spacing
22 Apr 2019
I have a tandem with 145mm drop out spacing and shimano tandem hub. Adjusting the front derailleur with a 113mm bottom bracket. It seems to me that 118mm would be better. Any thoughts?
113mm would be for a 135mm b/b, longer would probably be better, eg 118 as you suggest. despite how it seems, this isn't an exact science!
Do You Have Shorter Models

Hi, in the past you offered 145 and 150mm models, will they be available again?

These are all we have i'm afraid, they have been discontinued for a large number of years so we're just selling through the sizes we have left.

7/8 Or 9/10?
12 Jun 2015
is this item 7/8 gears and chain compatible?
or is it for 9 speed?
have you got a 7 gear compatible crankset?

This part is sold as a crankset only so does not include any chainrings, you can fit any 110BCD chainrings you want to to this crankset so you could easily fit 7spd compatible rings to it.
