Bicycle Mechanics - Slick tires

I have started riding my mountain bike on the road and would like to get slicks.

I currently have 26x1.95 I have been told I could go as low as 26x1.25 or 26x1.5.

Is this correct what do people here recommend.

Thanks

Yes.....................

Said it before and I'll say it again... Specialized Fatboys 1.25". SUPERB - zero rolling resistance at 85 psi and smooth, smooth, smooth...

Could you attempt to quantify that in terms of effort/performance (speed increase?)?

Much less effort, more speed - subjective, but there you go... Other main diff if you're used to 2.1" is the pain and discomfort when accidentally hitting potholes in the road at high speed - quite jarring on the arms.

Specialized makes a 1.0 inch tire for 26 inch now....

I ordered some last weekend

Yes, one inch tires are the BOMB!

I have Top Slicks (26x1) no flats or problems in over 500 city miles.

Edit: Make sure you have crank arm clearance (to the ground).

1inch?? Holy cow! How much are they?

DO IT. I run cheapie 1.5" semi-slicks on my rigid mountain bike, and its GREAT. Much faster, easier. I'm going to 1.0 slicks when I do a rebuild on my bike, should be even better :-)

The specialized are 30 each though

Dont forget to recalibrate you computer because the wheel circumference will be smaller.

I concur with all of the above.
but I do regret that actually I purchased a Hutchinson Python Gold 1.9 kevlar (knobby) and what I really wanted was a Vredestein S-Licks which were reviewed in Cycling+ Dic 03 as one of the best slicks on its class.

Is anyone on the market for a dry dirt racing quality knobby hutchs?

Performance Forte 26/1.5 Kevlar.....90 psi good slick at a reasonable price. I have about 500 miles on them with no flats yet

I currently have 26x1.95 I have been told I could go as low as 26x1.25 or 26x1.5.

If you're interested to know...

A couple of studies have reported that with slick tires, the fatter tires tend to have lower rolling resistance (but more weight and hence less speed uphill) than narrower tires.

on the other hand, the average narrow tire will inflate to higher pressure than the average fat tire.

Thanks for the info, I have ordered 26x1.5 slicks for the bike. I will let you know how I get on.

I do not have a great deal of first hand experience comparing tires, but Sheldon has a bit on this:



A common debate among cyclists centers on the issue of whether a wider tire has more or less rolling resistance at the same pressure. The constant pressure is proposed because it appears more scientific to eliminate this as a variable, but this is not realistic in practice. The short answer to this question is that, yes, a wider tire of similar construction will have lower rolling resistance than a narrower one at the same pressure. This fact is, however, of no practical value. If you are comparing two tires of similar construction, with the same load, and the same pressure, either the wider tire is overinflated, or the narrower tire is underinflated!
