Any chance of trying that caliper and wheel on a different bike to see how it sits?

UPDATE….. It’s sorted now !!!

Ive fitted the correct disc and some new pads and also a couple of new brake mounting bolts. Now it’s squeak free.

Thanks for everyone who suggested ideas to remedy it.

Ah, good. STW thread catharsis!

Nice one, glad it’s now sorted and you can enjoy it.

I was going to sell it but the more I ride it the more I like it.

I think they’re good frames, enjoyed borrowing one on several occasions

Mark 1 go at the top of the seat tube cluster

Mark 2 seem to be OK

Great design, would only be tempted by a fireline as a replacement

Just put one together out of my spares pile for a shipping to the outlaws in Spain for a holiday ride…gave it a quick test and I likey a lot
