What's the difference between these (29'er) - I know the EX's are a bit lighter. Specifically, are there any differences in terms of ease of tyre fitting / sealing etc.?
thanks
The Ex have a thinner side wall but the rim is a wider.
Ive got a set of Arch Ex rims, hans dampf and a x king on the back. I put a tube in for 1 day to help get the yellow tape and tyres seated properly. Then removed the inner tube, put in valves and i actually pumped the tyre to 40psi with out sealant, with no air escaping from the gap between the rim and tyre. The x king was leaking through the thin sidewalls (not a tubeless tyre but its ok now ive put sealent in it)
Tyres are tight but once you have fitted them a few time its easy.
