- Reviewed in the United Kingdom on 14 April 2022I've previously been using a folded over bit of paper to do this alignment task. But it's more difficult to get inside the gap. So I bought the BIRZMAN clam and it's proved so much easier and faster. Have used it for different rotors for my bike as I have two wheelsets, one for gravel one for road. It works every time and is very quick to do. Just loosen the caliper bolts, slide the clam in place, squeeze the lever and tighten the bolts. Job done in seconds, no annoying rotor rub noises. This pack includes three which is good value for money I think over the competition. One for my jersey pocket, one for the toolbox, and a spare for when I lose one of the others!
- Reviewed in the United Kingdom on 23 January 2022I had become accustomed to a lengthy trial & error faff in trying to centre disc brake calipers and this brilliant little tool has simplified the process no end. I got a perfect result at my first attempt. Still a bit puzzled why there needs to be three in a packet though.
- Reviewed in the United Kingdom on 19 April 2021A clever idea that allows you to get a reasonably good alignment of your disc brakes. The shape isn’t quite right for some Shimano brakes in the fact that you cannot spin the wheel freely when the clam is inserted. Notwithstanding, this is a useful tool and is very easy to use.
- Reviewed in the United Kingdom on 26 November 2024Pricey for what it is but does what it's intended for. Makes setting up the caliper much easier and more accurate than just pulling the brake against the rotor without a spacer. Careful when removing from the packet, I managed to slice my finger a little.
- Reviewed in the United Kingdom on 11 September 2022After having abit of a difficult caliper fit, these can aid in getting a good alignment, thou these are really only design to fit rear caliper, maybe works better for certain brand but shimano m395 not so much
- Reviewed in the United Kingdom on 6 June 2022Does what its supposed to. Comes in a three pack, which actually makes sense. I keep them in my toolbox, saddle bag and commuting bag. YouTube a video for perfect alignment, and you will have 90% less rotor rub.
- Reviewed in the United Kingdom on 27 September 2023Super useful to quickly set your discs and have no rubbing. Loosen calipers, slip this onto the disk and rotate the wheel a bit to position the clam so it between the pads and caliper. Squeeze firmly and hold the the lever until you've tightened the bolts. Remove the clam & job done. 2 mins. Much less faffing.
- Reviewed in the United Kingdom on 19 January 2022Works well. Maybe prefer a smarter design that avoids having to touch the part during insert/removal, to void oils from hands transferring to brake pads.

xyz1Reviewed in Germany on 20 June 20215.0 out of 5 stars Sehr praktisch!!
Habe zuvor x-mal versucht, die Scheibenbremsen einzustellen. Insbesondere habe ich versucht, die Einstellung optisch, u.a. unter Zuhilfenahme einer Leuchte, vorzunehmen. Auch die empfohlene Vorgehensweise Schrauben der Bremse lösen, Bremshebel anziehen und angezogen halten, Schrauben wieder anziehen, hat nicht funktioniert.
Mit dieser Einstellehre geht das wunderbar und gelingt auf Anhieb. Die Lehre funktioniert für Bremsscheiben bis 2,3 mm Stärke. Bei meinen Bemsscheiben (Magura, 2 mm) passt es.
Es ist dreimal die gleiche Lehre in dem Set.
Vielleicht ist der Preis ein wenig hoch. Aber wenn die Einstellung so einfach wird, ist es mir das wert.
Falls ich beim weiteren Gebrauch andere Erfahrung mache, werde ich die Bewertung revidieren.
