I'm looking for a cyclocross/winter/beater bike. I'll consider any combination of the three categories. What are the current value buys in bikes that fit this description?

I just read the section on fixed-gear riding in Off-Season Training for Roadies. I know it would benefit my pedal stroke, but couldn't I accomplish the same results on my regular bike by simply selecting a gear and not shifting for the entire ride? 

I purchased a new frame, now my heels hit the chainstays on each pedal stroke. I never had this problem before and haven't changed my pedals or cleat position. What gives?

I have an old Trek 800 that I'd like to set up like that so it's better for rides that include both pavement and dirt. What do I need to make the conversion? 

What you carry in bike bag can keep you on the road longer.  Here's our recommended list of bike-bag essentials for rides up to 100 miles in rural areas.

My race bike has a stiff aluminum frame. After a hard ride, my legs feel much more tired than they do on my steel-frame training bike. Is a stiff frame harder on the legs?

When I purchase a new bike, should I have the shop measure me for the proper fit or simply match the current size of existing bike? 

I've always ridden mountain bikes, but some friends switched to road riding and love it.  What would be a good entry-level road bike to use for racing and for training? 

Could you recommend a new bike that's under $800 and will be suitable for towing a trailer when I tour? I ride about 15 miles a day and 25-50 miles on weekends.  We have an answer to this difficult question

Ten years ago, we thought that a 22-pound bike was light and anything under 20 pounds was so gossamer as to be scary. Now the standard has changed so much that 16-18 pounds is the norm for high-quality road bikes.  To lighten a bike, where would you get the best bang for my buck: wheels, fork, frame or drivetrain? Or should you invest in a whole new bike? 

I own a hybrid bike but ride tours where everyone else has a road bike. I've never had a problem keeping up because I train hard during the week. But I wonder -- if my average speed on a typical ride is 17 mph, how much would it increase if I got a road bike?

I will be racing in a hillclimb, road race and time trial. I have two road bikes: a titanium Seven Axiom with Ksyrium wheels, and a steel LeMond Zurich with standard 32-spoke wheels. The latter weighs about 3.5 pounds more. Should I install clip-on aero bars on the Seven for training and the hillclimb? Or rig the LeMond for time trials so I can train on it all summer?
