58Mm Chainline
By
29 Jul 2016
Hi,
Can you please advise what BB size is required to give the new Rohloff required chainline of 58mm?
Also, are these JIS taper cranks?
Many thanks.
SJS Customer Service:
Hi,

For the new Rohloff chainline you'll need a 121mm bottom bracket. This chainset does require a JIS bottom bracket.

Thanks.
Brompton Crankset
By

Sir.
I am looking for a 39t crankset with chain guard for my boompton 2015 model. Please let me know what modification i need to made in order able to have this strong light 39t crankset works on my Brompton.
SJS Customer Service:
Hi,

If you fit a 107mm JIS bottom bracket to your Brompton then in theory you should be able to mount this chainset. However clearances are tight on a Brompton frame and we have had issues with trying to fit other cranksets before, so we cannot say for sure whether or not these strong-light cranks will clear the frame. The only over thing you will need to modify is your chain length as it will be longer than needed.

Thanks.
Bottom Bracket For 40 Mm Chain Line
By
19 Sep 2015
Hi

I want to match this to a Sturmey Archer 2 speed 120 mm hub. Should i switch to a 107 or 110 bb?
SJS Customer Service:
Hi,

This chainset is designed for use with a Rohloff hub so with a 118mm bottom bracket will give a 54mm chainline. To work with a 40mm chainline you would need a 103mm bottom bracket, with a bottom bracket this short you would have to be careful of the amount of clearance your frame has though.

Thanks.
Chainguard
By

Is the chainguard single...as in the product title...or double..as in the further description? This isn't clear.
SJS Customer Service:
Hi,

This chainset is supplied with a single chainguard fitted to the outer position of the cranks.

Thanks.
End Bolts?
By
01 Sep 2014
Does the Stronglight Impact Rohloff crankset come with end bolts?
SJS Customer Service:
Hi,

Yes, these cranks come with the end cap bolts.

Thanks.
Compatibility
By
26 Aug 2014
Is It compatible to Brompton? I need chainset compatible to Brompton. What can you recommend?
Thanks,
SJS Customer Service:
Hi,

Unfortunately this chainset would not be compatible as the chainline is much larger than what is required on a Brompton. Without some large modifications none of our single chainsets other than Brompton's own will be compatible with the Brompton bikes.

Thanks.
127 Mm Seems To Be The Bb To Go For
By
20 May 2014
They [Stronglight] specify this longer axle specifically for Rohloff and 118 mm for some other gear hubs with chain tensioner like Shimano Alfine maybe
SJS Customer Service:
Hi,

Stronglight do recommend the 118mm option with this chainset for Rohloff hubs. The Impact single chainset on Stronglight's website which they recommend the 127mm option for is not designed for Rohloff hubs.

Thanks.
