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"

Hello, we cannot confirm this as its just an adapter.

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

Can this be used instead of a spacer on a Ahead threadless fork steerer?

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
We simply could not recommend it.
