Velo Orange say you can adjust the radius of their metal guards, at least enough to make up the 28/700 difference. There's a guide somewhere but essentially you squash or spread them all the way along and it changes the radius.
Thanks, just read the Velo Orange guide. Yes, they say that you can use 700 guards for 27" wheels....bit not about 28" wheels
Bead Seat Diam. (BSD): 700=622mm, 27"=630mm and 28"=635mm
So, 28" is 13mm bigger diam than 700c......plus I've got 38mm width tyres fitted......think it'll be very tight!
no 28".......only 650 / 700?
