    If you own a braze-on front derailleur and then purchase a frameset that requires a clamp-on front derailleur, this is what you need so you can keep using the derailleur you already own. It transforms a braze-on front derailleur into a clamp-on style in a matter of moments. You'll need to choose one of three sizes -- 28.6mm, 31.8mm, or 34.9mm (aka 1-1/8", 1-1/4", and 1-3/8" respectively).

    Two notes of interest: These clamps are 100% compatible with both Shimano and Campagnolo front derailleurs. Also, the 28.6mm clamp isn't made by Shimano. Shimano doesn't manufacture a 28.6mm clamp. Rather, it's made by the highly regarded company, Problem Solvers.

    It works but....

    Yeah, its a pretty simple concept and it does work I had a few issues on my Cinelli cross bike build. It seems this adapter is meant for Di2 derailleurs as there is a lot of vertical surface area that I assume would make contact with the electronic motor that was left unused by the 105 mechanical I am using. As a side result of this I had to mount the clamp band in a position that interfered with installing a bottle cage on the seat tube. I ended up going with a FSA adapter that works better, has better build quality and was cheaper.

    As advertised

    I've used it several times

    Works as it should without issue, at a great low price. Quality product for the money.

    No fuss.

    Easy installation and adjustment. Just flat out works.

    Simple, durable

    I've put it through the wringer

    Again, this will sound silly; but this just works. I have no complaints or anything negative to say. They're just awesome.

    Easy does it.

    I've used it once or twice and have initial impressions

    Quick fix for getting your braze-on to a clamp on frameset. Nothing flashy here, it does the job well. Secure, sturdy, cheap.


    My bike frame is a plain TI without any paint. Would it fit well since it is a case of metal on metal? I afraid it would (somehow) slip. Or, do you have any suggestion?

    Has worked well on my Merlin ti for decades.

    3m clear packing tape under the clamp


    Is there any reason this wouldn't work with a SRAM Apex front derailleur?


    Can i use this for my dura ace 9000 braze on? Is the 31.8 right size for Boardman SLR ?

    Yes, this derailleur clamp will work with DA9000 braze-on front derailleurs. You will need a 34.9mm clamp for the Boardman SLR.


    Is this compatible with dura ace 9000 braze on derraulleur?

    Yes, this clamp will work with DA9000 braze-on front derailleurs. If you have any questions, feel free to contact me. brett@competitivecyclist.com
