Canyon want £40 for a single press Tool to remove my rear shock pin for the shapeshifter mount.
Can I get a better set for less money???

What does the kit / mount look like? Would something like this work..?

Which Strive?

The press they do (650b at least) is quite straightforward – bolt & domed washer push the mount kit out into the receiver. I can measure mine if you want to put one together yourself.

Don’t think I paid that much but for how much I’ve used it, it was worth it. See RRP presses vs threaded rod & washers.

I take it it’s this one you’re after?

Which takes the piss really. I bought one in June 2020 for £13.95.

Maybe they’re down to their last few?
