Cheers, Perhaps I'll try the narrower bluemels. Read online they have a smidge more clearance than the Chromoplastics due to shape. I think the tyres are actually closer to 30mm despite being labelled 28s. I'll measure them later.
Yeah the shape is different, chromoplastics are boxy, the bluemels are rounded so you can tuck them up in the caliper properly, also wouldn't be surprised if 45mm blumels and 32's fit
Also have a question, has any one here fitted a 1 inch steamroller fork and threaded it for a quill stem?
my 35mm bluuemals fit on there perfect with 28's
