BBB BSP-90 ShiftFix Front Mech Clamp.


  • Aluminum front derailleur clamp.
  • For frame tube diameters: 31.8 and 34.9mm.
  • Weight: 18g (31.8mm).
Solid clamp for bikes without the braze on mech plate.
Works well with Shimano Ultegra front derailluer
A great solution to the number of braze on front mechs out these days. The piece is light and spreads the clamping force across a wider area than most factory clamps. I was surprised by the nice fit and finish of this part.
Works great and nice price. Stiffer than the carbon band I had before (which eventually broke), and shifting is as least as good if not better.
Quality light weight clamp, no issues
No complaints whatsoever. A functional and unobtrusive design which is easy to fit.
Gets the job done and feels nice and sturdy! Great price also.
Does exactly what it is supposed to do. I like this design better than some others at the clamp is wider so spreads the load more over the seat tube.
Strong, light and compact. I bought it because the previous clamp brushed the case when I fitted 25mm tyres. This solves the problem, although I did have to shorten the clamping bolt for similar reasons. My only criticism is that the mech side of the clamp is flat - so there is only one position for the mech, which is why I had to shorten the bolt.
Does what it's intended to do. Note however that it doesn't include the bolt to hold on the derailleur, so you may have to procure another bolt if (like my Record braze-on derailleur) the bolt supplied with your derailleur has a captive curved washer on it.
Seems to do the job, haven't noticed it since I installed it.
Does the job perfectly. Converts one of the newer direct mount front mechs to a more traditional clamp on type.
Solid and very light.
It is light and it looks good. Ideal choice.
Light and perfect fit
Quite bulky and ugly looking when its on the frame; there are much better looking, sleeker clamps available, but they are more expensive. Other than that, it works well - there's minimal height/drop adjustment to be had at the mech fixing point, but the band fixes securely.
Had toget one of these as there were no band on 105 front mech's in stock. Does the job well, strong, secure and light. Good on a carbon frame distributing the clamping force
The clamp was perfect, just what I needed to complete a build. The Mech bolted straight onto it without any issues. My roadbike is now ready to go! 5 stars to merlin for a great item at a good price.
Light and secure clamping.
Very neat and light piece although positioning of the Allen bolt gets in the way if you are fitting Crud Road Racer MK2 Guards wit the extension to protect the front mech.
