Cyclocross Racing - Too big for Aluminum Frame?

I'm looking into buying a cross/cyclocross bike and would appreciate some expert advice from the experts like yourselves (thanks VERY much in advace). Here's some background, what I'm looking for and what I'm concerned about:

A -- I'm about 6'5" tall and weigh about 220-225 lbs.

B -- I am not a racer but enjoy recreational/serious recreational riding (20-50 mile rides for fun, exercise and friends)

C -- I have a steel road bike (8 yr old custom Zinn w/ Durace) and am looking for something to use for unpaved trails (crushed limestone typically), the rougher streets/Chicago Lakefront paths and nastier weather. (Note -- I'm 50 and not planning to ride on terrain any worse than the above)

D -- I'm interested in the Specialized Tricross (alum frame version) but I'm concerned about the large aluminum frame handling this stress of weight over time.

I'm hoping to get some guidance on the following:

1 -- Is the Specialized Tricross a good choice -- any other specific make/models you'd recommend. Unfortunately, the reality of the current economy makes the possibility of another expensive bike impossible so economics are part of the decision equation).

2 -- will an Aluminum frame work for my size and weight?

Thanks !!

I wouldn't obsess over the material. I would expect the larger frames to be built up accordingly. If you are really sold on steel and looking for reasonably affordable bike look at Surly Cross-check and Bianchi Volpe.

225 lbs. isn't all that heavy, especially given your height. Besides, I'd be more concerned about your wheel and brake choices more then frame material. Too many of the stock cross bikes skimp on the wheels and brakes in my opinion.

Besides cross bikes, you may want to check into touring bikes too. They have clearances for bigger tires and are built tough as well. They typically come with heavy duty tires that are good for paved and unpaved roads. Cross bikes come with cross tires that are great on dirt and grass, but not as good on pavement. Cross tires also tend to wear quickly on pavement.

Also, since this is the racing sub-forum, you may not get much relevant help. You may want to try the main cyclocross forum. There's also a Clydesdale sub-forum that may help as far as wheel choices and the like.

And don't rule out cross racing, it's really fun!

Looked into both and like what I see. Now to figure out which is best and which fits best.

Have a Great New Years!
