Hi all,

I'm new to the road bike game. I purchased off ebay a Cannondale R800. Love the bike, but I have one problem hopefully someone can help with the following:

Wheels are CODA Expert hubs with Mavic CPX 21 rims and also, Continental Ultra 2000 tires.

These seem like good equipment, but I am 5'10" and 250 pounds. It feels like these tires are always flat! I know it's from my weight and the "skinny-ness" of the tires.

I'm not going to get a whole lot lighter...I'm built like a brick you-know-what. So I need help on a set of wheels and/or tires that can accomodate the heavier set among us.

This was no problem when I was mountain biking. I just crashed the crap out of my Panaracers...but I'm short on knowledge for road biking. Can you help? Thx!

The short solution will be to ensure that you are using a wider tire (700 x 25 if it will fit; 700 X 23 minimum) and FULLY inflating it. Ya know, get a good floor pump with a guage and put 120 or so PSI in those babies.

But also the CXP21s have a notorious problem for spoke breakage, and a bigger rider may find it is only a matter of time. Wait and see.

Anybody know if a 28C tire will clear the seat tube on a Cannondale R800?

If so, that's definitely the way I'd go if I were a heavy guy. The larger cushions will make the ride on that relatively stiff Cannondale frame more comfortable. They'll handle the bumps better than skinnier tires, making the bike less skittish in corners. Air 'em up to 100-110 psi, and they'll be fast.

Continental Ultra 2000s come in 28C. I've been running a pair on my commuter bike and they aren't losing tread (rubber) nearly as quickly as 25Cs do. They seem to last a little longer.

I tried the conti ultra 2000s for a very short time. absolutely did not like the ride. the sidewalls are very weak, a problem ive heard about many conti tires. they otherwise seemed like good grippy tires but at 150lbs, i should not be stressing out tires like i felt i was.

I agree with everyone else here tho, try a slightly wider tire or one that can be pumped up much higher.

good luck.

As a fellow big-guy, (235#) I have found the only sure answer is to save those pennies until you have enough to get yourself a set of custom-wheels from a good builder. Pick a nice hub, a beefy rim, and then go 36 spoke. You shouldn't have too many problems after that . . . and they'll move from frame to frame with you if you change your ride, so the money is well spent. Also, better hubs are always a noticable improvement, so just use this as a good excuse.

Hey, at our size we're already 80lbs. above where we "should" be(not that I would want to clock in at 160!). Trying to save a few pounds on the bike is just silly, so I figure get the bomb-proof stuff and go merrily on your way.
