Model/Year: 2009

Pros: Large volume and low rolling resistance.

Cons: Not true to size. No tubeless version available. Seems to have issues holding Stans sealant.

Recommendation: These are decent tires if you run them at lower tire pressures. Unfortunately they don't seem to hold Stans sealant incredibly well making lower pressures dangerous b/c you have to do it with tubes.

Pros: Light weight, long lasting tread. High volume smooths out the rough stuff.

Cons: The profile is too tall for a 2.4. It seemed like it should be a little fatter for better transition into the corners.

Recommendation: A decent tire that I'd consider running again.

Pros: Weight of the 2.4. Low rolling resistance.

Cons: Tires can get loose on anything that isn't hard pack or dry rock and pavement. Poor traction on loose rock, roots or wet areas (most east coast riding). 2.4 sizing is questionable; seems more like a 2.25

Recommendation: This is a pretty good tire when used stricktly on hard pack in dry areas. It rolls very fast and is pretty light too when you use the 2.4 version. When you try it out in other conditions it leaves a lot to be desired though. WTB markets it as being good on "hardpack to loose" terrain but I would have to disagree with the "loose" part. The front tire will drift like it has a mind of its own and don't even waste your energy trying to get traction on wet roots with these boys. I'd like to try them in on a full "slickrock" trail as I think that this is where they would excel. If hardpack is your trail, you will not be disappointed. But, if your trails are a little less forgiving, go for a more gnarly tread pattern.
