I have a base model Tricross and was thinking about using it for group rides. At first, the guy at the shop wanted me to switch out tires for some 28s that run about 100psi. then he found out that I was running (stock) 32s at about 100psi and he was all like, never mind. the tires were Gravelburners or something with gravel in them. As it turns to, Im going to go look at a used set of road wheels that I want to pick up for the bike with a set of road tires.will standard road wheels fit a cross bike frame? (and the big one) what tires would you recomend?

BITD Tri Cross was just the tires.. A Knobby with 3 lobe knobs .

NB: as Tire volume goes up the tire pressure is reduced Proportionally .

Wide expensive casing High TPI tires will roll just fine . you will pay more to get that .

I like my X'Plor Ush, 120 TPI tires. They seem to roll quite nicely. I haven't put that many miles on them though, so I can't say how long they'd wear with heavy use.

If you drop down to 25mm or 28mm, there will be a large variety of "road" tires available, then it is down to your choice. I would encourage you to choose something with flat protection. Gatorskins, Gator Hardshells, Refuse, etc. Many other big name tires at least have some flat protection.

mr,grumpy 

I don't know what BITD is but Tricross is the model of bike that I have. And I don't want to "pay" any more than I possibly have to! I'll be extremely lucky to keep up as it is!

So, yes, I would like to step down to a 25 or 28. Probably a 25 since the Bike Shop man dismissed 28s when he found that I could run my 32s at 100psi.

You aren't gaining anything running 32s at 100psi other than a rough ride. If anything you are increasing rolling resistance by doing that.

I dont follow what you are trying to get at with respect to the LBS dismissing 28s due to what you run 32s at.

I am 230# and run some 32s at 100psi. I run 25s on a different bike at 110psi.
If, due to bike and rider weight, you run 32s at 100psi, then get some 28s and run them at 110psi or something like that.

Tire inflation levels are a total inexact science. Its an absolute art, actually, due to so many variables(true wheel size, true tire size, rider weight, bike weight, riding style, pinch flat risk aversion, etc).


Gets some 28s if you want 28s. Get some 25s if you want 25s.
Personally, I would get some light and supple sidewall 32s. You wont be faster with cheap 25s compared to light good 32s.

Curious as to why the OP chose 100psi for his 700x32s. I've never run more than 90psi in a tubed 700x28 (even when I weighted more than the OP) and in a 700x32 I'm running pressures between 70-80psi.

All you will get switching to a 700x25 is a much harsher ride, and tires than don't last as long. I'm riding wide 700x28s (which mount to almost 32) already have my next set of tires (700x32) and the tires that replace those will likely be 700x40. IMO, ther's no reason to run a narrow tire here in the 21st century unless you have a frame that won't fit a wider tire. Switch out the gravel tires for fast rolling 700x28s or 700x32s. Unless you want a harsher ride. Then go for those 700x25s.

I don't understand this. But it doesn't matter, because the question that was actually asked was this:



Yes, and any 700x25 or 28 that they have at the shop for $30 or less.

I think my Tricross is 2011.

As far as wheel sizes, I think it simply uses 700c rims with 130mm OLD in the rear, and 110mm OLD in the front. It should fit most current "road" wheels, although the brakes would need adjusting for narrow rim widths.

Cross wheels are likely built stronger than road wheels, but it wouldn't be necessary for road riding.

Is your Tricross 2010 model year or 2011 model year (sold in fall of 2010)?

I believe all 2011 and 2012 Tricross frames were recalled for carbon fork replacement.

I'd find a good 28, 30 or 32 and go with it.

I have a 2009 s-works tricross and run 28mm GP4000s with wider rims. Comfy ride and low rolling resistance. I pump to 80 or 90 psi and don't touch them for 2-3 weeks and they gradually get softer. No problem with pinch flats.

mr,grumpy 

How's that? Thats the pressure range. Low is like 65 and high is 100. How does that make MORE rolling resistance.

mr,grumpy 

Im not sure. Ill have to look into that....

The 33.3 wide riv bike tires Jack Brown BLUE 700c x 33.333 Tough - 10092 - BLUE Ride nicely .

I Have the Green version, to use my CX as if a road bike..

phatfree

I use my 3X as a rando bike and I use Jack Brown Green's on it. 70 rear and 60 front.

mr,grumpy 

n+1=solution. Fixed it. Leaving my TirX alone.
