Kona Sex One rear V-brakes

Does the brake arm hit the boss or is it just the interference with the brake noodle?

The brake arm hits the boss

Have you considered mini-v brakes? I’m not sure on lever compatibility, though they may clear that boss.

Thanks for the reply. Interestingly I did a search this morning for short arm V-brakes and found the mini V-brakes, it might restrict the size of tyre but not by a great deal, 90mm arm length instead of 103mm-

This is my Sex One, I'm pretty sure it un screws- mine came with V's and I've never looked in to switching it back (too many other projects I'm more interested in). The bike is currently at my storage- I have to go there tomorrow, I'll have

I looked for the flat sides on the boss and couldn't find them, I also tried an Allen key which didn't work, fairly certain it's welded on. I'm reluctant to cut it as I'd prefer to keep the frame intact.

Looks like it's not removable- I didn't look super close but mine appears to be cut. looking at it a little closer in the pictures, it does look threaded, but this is cut for sure.

Time for Magura hydros? You won't regret it.

If you go to mini-v then you need a conventional canti brake lever.

Thanks for all the feedback, in the end I went for V-brakes on the front & cantilevers on the back, fortunately the levers are adjustable for cantis or V-brakes, I like that this retains the rear cable hanger that came with the bike.
