ConsA bit pricey for what they are...
ProsFit for purpose/one of the few options around...
These front tandem cranks were required in the shorter 160mm length that Thorn cater for which make the comfort on the front of my Voyager improved. Straight forward fit and usage.

Consexpensive for finish
Prosgood size selection
Expensive for the quality of finish (back of spider). But a perfectly functional budget crank in a good selection of lengths, which is why I needed it.

If you need shorter cranks then there is little choice of supplier please lift the quality or drop the price though.

Can i use it on a single speed
30 Jul 2018
I have a single speed that has a square taper want to convert my crankset to a 110mm BCD could it do it (purpose it to mount then with a chainring from absoluteblack for gravel)
These cranks are designed for a tandem with the chainrings on the left hand side, so probably not suitable for your bicycle.

4 arm 104mm BCD version
22 Jan 2018
So what I really need is a 4 arm 104mm bcd version of this with 165mm cranks and gxp compatible... Am I asking the impossible? Oh, and preferably in black LOL.
Hi there,

Sram do not offer a suitable chainset for those specifications, I would suggest looking to change your bottom bracket type and you will be able to find more options available.

GXP to square taper BB to use these?
18 Jan 2018
Hi, we have a Dawes Discovery Twin and I'm looking for 165mm cranks for the front. It currently has a GXP bottom bracket. Can I replace the GXP BB with a square taper style and then use this crankset? Any recommendations for a suitable BB? Thanks.
Hi there,

Yes no problem,

Use SJS Cycles part number : 26973S113 for 73mm frame or SJS Cycles part number : 26972S113 for 68mm frame.

What Would I Need To Fit This To My Bike?
09 Mar 2016
I have a BBUB26 (spindle 113mm), and a triple chain ring set with ratios 32/42/52 all shimano components.


This is for the front of a tandem with the cranks with the spider being on the left hand side so although you could fit 3 chainrings there would not be much point as the front derailleur would not work as they'd be on the wrong side of the bike.
