2.3" vs. 2.1" tires?

[SadieKate]

You need to go to the manufacturer's web sites to do your research. Many tires come in both tubed and tubeless versions, as does the Conti Vertical. It is the same tread as the Explorer but in a 2.3 width. Yes, wider tires are heavier than 2.1 but offer so many advantages you will never notice the difference. Just compare the weights and patterns of various 2.3 tires. Trust us on this one. I can't tell you the number of really, really, good riders that will say "get the widest and lightest tire for your terrain." You will not regret it.

Better traction and handling versus a few more grams? You'd rather slip, slide and fall down more for the sake of a few grams?

PS - I use the ProTection versison because foldable tires are lighter. And it's really not the rim you need to check for the width, it is the clearance on your bike. However, I use these tires on a XS 2005(?) Racer X so you should be OK.
