hey all,
First of, my apologies for the lame question but I've searched everywhere and can't find the answer to my question.

What's the widest tire I can put in the rear of my 2009 Stumpjumper FSR Expert 29er?

I'm a clyde and I'm tired of my 2.25 conti mtn king burping. I'm running a 2.4 ardent up front, and was thinking I'd like to go with a 2.4 in the back too.

Thanks!
