read the reviews and got a pair of 2.4 BC protection, grippy, fast and light but now up for sale ,
i did not like the transition to the side knobs, there is a drift zone before you get there and its fine if you throw the bike down into every corner but on a long rides on unknown trails i found it got a bit tiring.
great tyre in every other respect,
2.4 is about the same as a 2.2 RQ widthwise +/-
