Is it better to ride a MTB with suspension fork or undersized MTB without on the road?

Question

I'm doing some long rides, and I have a well-fitting Gary Fisher Big Sur with suspension fork, and an older, undersized Univega Alpina Uno with a traditional fixed fork. Which would be better to do long road rides towing a trailer? (and yes, I know the right answer is get a road bike. Downtube broke last week and is being repaired).

Answer 1

Use the bike that fits. I would be inclined to set the pre-load on the suspension fork pretty high to minimize bounce while standing and climbing. The only other disadvantage is the weight, but fit is definitely more important than weight.

Answer 2

Having the bike with the proper fit is key. It will be a more comfortable ride plus the day after will be easier on your body. As always make sure to stretch before and after your ride.

Answer 3

It'd be great if your suspension has a lock out. Use the bike that fits. the suspension might make pot holes fun.
