Magura rim brakes with different rims?

Hi all,
I am wondering how much vertical adjustment there is (if any) for magura rim brakes? Is it possible for instance to put a 29er wheel on a 27.5" unicycle frame (ensuring there is tire clearance using actual frame measurements, and something like this - How to calculate Bicycle Wheel Size to work that out)?


There’s hardly any. If the brake mounts are for a 27.5" rim, then that’s the only size that will work.

I think the only way to do that would be to add another set of brake mounts on the other side of the frame, like Triton does on their frames.


Thanks so much. As I don’t have any yet, and I couldn’t tell for sure from the manufacturer’s spec sheets. I had suspected as much, but I thought I’d check the ever helpful users on this forum. The thing is I have a 26" wheel on right now and am on the lookout for a wheel on the local used market. I keep coming up with 700c/29 that might possibly work for a decent price, but I have been mostly ignoring the ads until today when I speculated that perhaps this could work. I don’t really want to put new lugs on. I don’t know how to weld aluminum/aluminium yet.

Thanks again,

for 26" and 27.5" I have this solution: 2 brake sockets

You can rotate the fork 180 degrees


That’s clever!


Yes, I had seen that in your catalouge. It’s just to bad that you can’t ship to Canada. Sigh. I love your store.

I can already ship to Canada. I only unlocked the surrounding European countries in the shop because there is a jungle of tariffs with different price zones that I have to assign to the countries. But if I have a specific request from a country, I will activate it in the shop. I have now unlocked Canada. Probably i can send this fork as a small package. (L+W+D max. 90cm) That would cost CHF 37.-. (-2kg). If you have any questions, please contact me via the email address in the shop

This is the reason I exclusively use disc brakes in the frame. Get a 36er frame and any size wheel will fit and brake works as long as a few details are met. Hub width is the same, disc diameters are consistent, best of the Uni world. That said, I don’t do that, I have many many many unicycles to choose and ride of all the sizes.
