n00b tube question:

[capnsavem]

i can see that DH/FR tubes are thicker and obviously that makes them heavier than regular or lighter tubes.. but if i dont race and just ride for pure pleasure, will it make that much of a difference?

oops- just think i found my answer- DH/FR are bigger and will only fit DH/FR wheel/tire setups?...

yay me.

In a word, yes. Thicker tubes will be heavier, obviously. This means it will be harder to pedal so you will tire more easily. It is rotating mass, at the very outermost edge at that, which means this is where you will notice weight the most. You will get less traction for the same given air pressure since the thicker tubes resist tire deformation more than a regular tube. On the positive note, you will be less likely to get a flat of any type with a DH tube than with a regular tube.

Hope this helps.
