here's a (hastily done) diagram with the measurements

this isn't exact by any means, but it should give a good idea of the size.

thanks a lot for those dimensions

i was actually unsure about getting these because i thought they might be a bit wider than what i wanted but now im definiteley getting myself a set

to reiterate, these are the 38cm ones available only from thebikebiz.com and NOT the 42cm ones that are widely available.

not enough world champion stripes or stickers, try again
