ConsChunky appearance

ProsVery effective

Works really well. Places the gear shifters about 10mm further out from the downtube compared to brazed on bosses so looks a little "chunky"

Can I use this on an aluminium frame 2016 Specialized Allen Elite

Barrel adjuster housing broke off and stuck for a solution. LBS says they are too busy to help ??

SJS Customer Service:

Hello, as we do not have your bike here to test fit this we could not say- if your frame tube is between 28.6 to 31.8mm then this will fit over it- however if its ovalized or in anyway not perfectly round then there is a chance this might not work. You must have this fitted by a professional cycle mechanic as you risk damage to your frame if this is not fitted correctly.

SJS Customer Service:

Nice idea, we've never tried it, looks like it could be possible but it's not recommended by the manufacturer so we can't say yes to this question, sorry RT 13/04/2020

Looking to use downtube levers on my 1996 Marin Bear Valley, I see that the max dia if this is 31.8,mm. I know it wouldn't be perfect but what do you reckon? Thanks,
Alex
