brake caliper went on the back burner and i got on with the rest of it.... i was a bit concerned that the chain line would be off when using a SRAM red crank. As a 1x setup as i was only able to use either the inner or outer chain ring position. Having sent an email to Wolftooth they assured me that the outer position would give me the correct chain line of 49mm, and it would seem they were right:
right then, all built up (sans bar tape)
happy with that.
and try as i might i could not get the bleed screw out, so i bought a new caliper (thanks for the suggestion @Simba) , at least i could fit a flat mount and not adapt my old post mount, that's something i'm taking away from this i suppose!
and the road tyres arrived too (700x38mm gravelking slicks);
a poorly child means i haven't actually managed a ride on it yet, but i'm off work next week and hopefully he'll be back at school.....
