Going from 35c to 28c...?

[Cosmicned]

Guys-

I'd much appreciate your advice on this- I have a Hybrid Felt QX95 for my general commutes- but the supplied 700x35c tyres seem a bit too 'off road' for my mostly cycle path/urban route - I like the bike, but it seems a bit sluggish on the road- I suspect the tyre sizes may be the issue - I have 19mm WTB Dual-duty rims- would 28c slick(ish) tyres fit ok...? If so what's a good one to go for less rolling resistance but reasonable puncture protection...?

I put 25mm tyres on my Croix de Fer, which has 23mm rims.

I went for Continental Gatorskins, which I'm happy with.

Hi Ben, I suspect your CdeF had 23mm TYRES not rims - even the hefty A319s on my Surly are only 19mm rims!

To the op - Sheldon Brown has 28mm as the smallest "safe" size for a 19mm rim, see here;

FWIW, I went from 32c (Vredestein Perfect Max) to 42c (Continental City Contact) and didn't notice much difference in speed (the 42cs at 50-60psi are much more comfortable though).

Hmm. The specs say the tyres supplied were 35c. The description for the rims is "Alex DF-23 all-black 32 hole"

The actual spec for the rims looks like it has an inner rim width of 15.7mm.

Ah, that makes more sense - a 23mm rim would be pretty burly.

I just assumed that DF23 meant it was 23mm!!

Heh The last Alex rims I owned were the DA22s that came with my Giant SCR2.

They were 13mm width

I recently changed from 38c tyres to 28c Continental Grand Prix 4 Seasons, 28c is the biggest they produce for that tyre.

So far excellent, light, low rolling resistance, excellent in the wet and apparently good puncture protection.
