Ok to put narrow tyres on a hybrid???
 
I currently have a Claud Butler Urban 200 hybrid (www.falconcycles.co.uk) it has 700x42 tyres. I want to put narrower tyres on for speed, maybe some 700x28 or 32. Is this ok to do. I read on web site that it wasn't a good idea to go from 700x42 to say 700x25. Is this true?

999,I wish that I could answer your question for certain, but cannot. However I went to the Falcon site, and looked at those hybrid/comfort urban bikes. Those are some nice bikes, until now I was unfamiliar with this brand. About how much does a Urban 200 cost, if you don't mind me asking?

At the bottom of this page, Sheldon Brown has a table of various rim interior width vs tire size. So if you remove your tire and measure the interior of your rim, you will know for sure.

Another trick I have discovered is that the outside width of your rim should NOT be the same width or wider than your tire. The reason: can you say pinch flats and rim damage?

You can put narrower tires on your hybrid. If your rims are real wide, you may be limited how narrow you can go. I believe www.sheldonbrown.com has some guidelines on this.

I was working in a shop that sold quite a few of these Urbans a year ago. I don't remember any numbers, but from memory, I'd say you'd be okay with 32s, but not 28s.

My Urban 200 cost me 400Euro. On the rim where the Vuelta brand sticker is located it says in small writing 21-622. Does this mean that 21s are the narrowest tyres that you can fit? Or that the true wheel size is 700c when a 21 is fitted?

21 is the width of your rim, so according to Sheldon Brown's table 35 mm would be the narrowest tyres you could use, although 32 may be possible.

I have a cyclocross bike with Mavic MA3 rims. Currently I have 700x38 tires for winter, but during the summer I use 700x26 tires. I wouldn't go any smaller than that though, and to be honest, in retrospect I think 700x28 would've been a better option. The 700x26 have a pretty harsh ride :eek:

Thanks for the advice. I think I'll go for a set of Continental Sport contacts. Which are 700x37 and, won't cause rim damage etc...These tyres are supposed to be fast and aren't too narrow. They'll be a lot better than the cheapo "CAMEL" tyres fitted as standard!!
