Recreational Cyclocross and Gravelbiking This has to be the most physically intense sport ever invented. It's high speed bicycle racing on a short off road course or riding the off pavement rides on gravel like :The Dirty Kanza". We also have a dedicated Racing forum for the Cyclocross Hard Core Racers.

Road tires for Cylocross Bike

I have the 2014 Jake the Snake that came with stock Clement MXP 700*33 cylocross tires on a Alex CXD7 wheelset. I have found myself riding mostly roads and have done 40-60 miles rides. I would like to bag a century and looking for road tires. I am leaning towards the Continental Grand Prix 4000S II, but unsure about the size. Will the 25 fit, or is it better to get the 28 size, which is better? Thankx

More than likely they will fit but asking tire opinions is like adding toothbrush opinions -you'll get 100 different ones and in the end what matters most is your preference.

My favorite tires now are panaracer pasala TG (35) but I also use schwalbe fat Frank (50). Both are preferred to anything smaller but that's me.

I'd either stick with what you've got, or go with 28's for the century ride. I'd also go with Gatorskins!

No reason to go smaller than 700x28. Continental 4 seasons and the 4000 are sold in this size and these are excellent tires for a Century. They are smaller than marked, and measure more like 26.5 mms wide.

The gp 4000 ride great. I'd go 28, 25 minimum if you absolutely want skinny, but 28 will do you well.

I have a pair of these on order and am excited to try them. Planning on trying out lower pressures for commuting, maybe pump them up a bit when going on longer rides with the gf.

Check out Tire Dimensions | Schwalbe North America, and scroll down toward the bottom of the page for the "European Tire and Rim Technical Organization Standards Manual - 2007." That gives some guidance on what rim and tire widths are good to run together. Note that the rim widths are inner dimmensions, not outer.

FWIW - I've got a pair of Conti CX Speed 35mm on one wheelset (for gravel / dirt / CX, etc) and a pair of Conti GP4000s (23mm) on one set of wheels for road / tarmac, when commuting on my Focus Mares. Interestingly, the Conti CX Speed tyres do roll very nicely on tarmac - they are just heavier and wear quicker.

GP4000s in 23mm would suit you fine - for tarmac. If you do venture onto gravel / dirt, then a CX tyre would be more appropriate, I'd reckon.

cheers

I wasnt a huge fan of the gp 4000.

I went back to my vittoria open corsa Evo cx's.

They fit my wheels easier, last longer, and feel faster.

I use Compass Stampede Pass on my Merckx when I have the Grifos off the bike.

Nicest rolling big tire I have ever used.

You can thank me later.

The CX Speed/Speed Ride tires do roll really well on pavement, but I wouldn't want to use them for pavement only. They are great for mixed pavement/gravel ride.

For the OP's actual question, you should be able to run 23's or 25's on your CX bike without a problem. The only potential issue putting small tires on a bike designed for fat tires is that the pedals will be a bit closer to the grount, meaning you could hit the pedal on pavement while cornering. However, most CX bikes have a pretty high bottom bracket, so I don't think this should be an issue. I used my old CX bike for commuting all the time, on 25c tires, and it was great. I just had a spare set of wheels with the 42's for riding gravel.

If you are using this bike for pavement-only rides, definitely go with a 25c tire. IMO, that is the best size for pavement-only riding. 28's or 32's would be ideal if you have especially rough pavement or might ride a bit of gravel, but I think 25's are the best for tarmac-only riding.

Of course sticking with same Brand the hard pack Course File tread is fine on the paved street and I'd Think, Gravel road racing

LAS Tubular | Clement Cycling, Cyclocross Tires, Adventure Tires, Mountain Bike Tires, Road Bike Tires or clincher ..


lower end and a bit slower rolling on the street, WTB 'allterrainasauraus' 32 has shown itself to be pretty long wearing as a decent trade-off.



But , yea, dead slick is probably lowest rolling resistance.. thin tread, Absence of puncture resistant features sheds tire weight. too.

Agree myself. Never was a fan of large tires because they were slow. It's about compound and weight. These tires are some of the best compound tires available and are as light as most 25's. But have the comfort of their size. I'll never ride anything less than 32's now.

I've run 23C slicks (Hutchinson Fusion 2) and they were fast but very harsh. I prefer a 28C or 32C tire since the volume gives a better ride and studies have shown that with the same tread, rolling resistance is actually lower for the fat casing but aero drag is higher, although that is a bigger issue above 25mph. Currently I run 32C Paselas and they actually feel faster than the cheapo Forte 25 C slicks I was running. My son has used the Conti Speed tires on the street for several years and really liked them.

I use 28mm Gatorskins on mine, and it's been great, though I've still gotten two punctures on them (each time, very skinny slivers of metal from road debris). I suppose that would have happened with any tire.

I have 25 mm Gatorskins on my CAAD9 road bike. They are a really durable tire - I've had zero flats with them in several years of riding. However, they don't seem to handle that well for me - high-speed cornering just isn't as good compared to the Rubino Pros I used to run on the bike. I have no idea why this is, but I'll probably replace them with a better-handling 25c tire when the wear out. With how tough they are, that might not be for a few more years!
