Roval CLX Wheels - Inner Tubes

[Pot Odds]

Just had a lovely set of Roval CLX 32's delivered having scored a brand new set complete with all bags and extras for £1030 from a specialized dealer - chuffed to say the least with the price and boy are they light !

Just a quick Q though for anyone who has a set of CLX.....

I will be fitting a set of GP5000's in 28c. What size inner tubes are others running on 28c tyres (I've only just moved to 28's on a new bike having run 25s on my previous bike). I would normally run continental race 28's in a 20-25c size in my 25's on the old bike. Do I need to get the slightly wider 25-32c version of the race 28's. The rim widths on the Rovals are a very generous 20.7mm internal and 28.1 external so I figured a 20-25c inner tube might be a bit small.

I might be asking a silly Q and should buy the right size for the tyre but had read some were using the 20-25c without an issue - thought id check in on any real world experience.

Thanks

The tubes you have will be fine, I use the same in the youth's 35c cyclocross tyres. Very stretchy, rubber...

S-works Turbo tubes or I'd run them tubeless
