Hiya~ Had new rims built onto Hope hubs.The old ones were tubulars the replacements are for clinchers.They ran close to the brake body.Now the tyre just touches.Some sites suggest shims in the vertical dropouts,this would give me the clearance needed.Is there anything available? L.B.S said there used to be but cannot help.Or is it a D.I.Y option.
P.S Bit of a Numpty in the engineering department so prefer non technical options
Have you fitted a different <brand> of rim to your bike? There are definitely size differences out there (700c Mavic Open Pro v the larger DT RR465 for example).
Best to start simple and look at your tyre sizing first. What make/size of tyres have you fitted? Some brands are def taller than others! IMO Vittoria tyres tend to come up smaller than stated (both width & height-wise).
