Has anyone got a magura brake they are willing to part with? I have found that for steep downhill i need one and I don’t have enough money to go and buy a new one for £60, and then buy the clamps, and a new seatpost, and possibly an extended lever.
I am looking around the mark of £40 and more if someone has an extended lever and/or a seatpost with brake lever attachment.
Keep bidding on them on ebay and before too long you’ll get one for a nice price. If you buy a pair from a bike you can sell the other brake, the evolution mounts and boosters (if they’re included) for nearly as much as the set cost you if you buy well. I got an HS33 that way last year that ended up costing me £4 (£45 for the brake set off a bike, sold one brake for £25, sold the evo mounts for £11, booster for £5). Of course you’ve got to buy the hardware to mount the brake on the unicycle, but it still works out pretty inexpensive - you should get within your £40 budget even if you buy all the other stuff new.
BTW - you don’t need to get a new seatpost. Just get a KH brake lever mount that fits under the saddle handle bolts.
