Maximum tyre width on Shimano RS10s

bails87

The external width of the rim is given as 20.8mm, but I can't find an internal figure.

Does anyone know what the maximum sensible tyre size would be for these? Shimano reckon 19-25mm, but if running wider tyres in the winter means new wheels, (as well as new frame and brakes) then I might as well just drive to work!

Why do you want something wider for the winter?

Either Ice spikers, or CX tyres for on the towpath.

In the winter I occasionally run Conti travel contact tyres on the R500s; 700 x 37 and these are fine, the only problem I get is the nobbles rubbing on the mudguard.

Have you got clearance for a 35c tyre like the Marathon Winter? I'm reasonably sure they'd fit the wheel (I have some RS10s and Marathon Winters at home - I could check)

No, not on the Ribble, the plan was to get a CX frame and swap all the bits, apart from the 105 caliper brakes, over to the new frame, then use that for winter (or if I like it, all year round and sell the carbon Ribble frame, seeing as the only road riding I do is commuting)

But....if it meant new wheels, as well as a new frame, forks and canti brakes then I could just go for a Boardman CX (£810) or a Voodoo Limba (alu frame, carbon seatstays and forks, 105, raceface finishing kit) which I could get for £630 (my local halfords has a couple left at £700, and I can get a 10% discount on vouchers) seeing as that would mean spending not that much more, but avoiding the hassle of swapping stuff over.

It sounds like they would work though. I have an idea of what's sensible for an MTB tyre on a certain width rim, but wasn't sure what the 'rules' were on the road side of things.

Edit, then I had a look at the cheap Carrera road bikes, the Virtuoso and the TDF one, for example, I could get for ~£250 and ~£300 respectively, despite being road bikes, they've got pretty big clearances, so could do as a winter 'hack' road bike?

Edit again: Actually, I don't want two road bikes!

I want to say the max recommended tyre size for the RS10's is 28mm but I can't find the link where I saw that and I have been looking at so many wheels of late I could be wrong.

That doesn't mean you can't run bigger on them I just don’t know how that would perform.

I went the Boardman CX route for the winter and extreme wet days - guards & discs make for a better ride and it has the clearance for the Marathon W***ers. I think it's a great compromise for an all-year commuting bike.

I'm being increasingly tempted by the idea of selling the Ribble and buying a Boardman CX to replace it.....

This is quite useful:

I am looking for tyres to suit my Mach 1 250 Disc Rims which will only take 700x28c and greater (I was hoping to try a 700x25c actually).
