I'm riding an 05 cannondale CX optimo on dirt roads and single track.The bike though not stock,weighs19.4 lbs. with pedals,computer, tool bag (no tools) and water bottle rack. I have a 32mm specialized Houffalitz on the front (a super tire in every aspect) and a panaracer 31mm cross blaster on the rear. The cross blaster wears fast but is very good when fresh. Problem is..here in new england the serious single track has wet rocks and roots, mud and ascents. The bike is incredible (better the me) but I find I get hammered on the rocky descents and lose rear(only) traction on the steeper slippery climbs, especially as it wears. Need more tire!!
It appears that a 35 or a 37mm rear tire is as big as I can go due to chainstay width. Any one have any specific brand/model tire experience in conditions such as this? Iwould like to keep the weight down as much as possible (don't we all) as that seems to be the secret to a 700c wheel bike in the rough terrain imho. No CX racing yet but if I could dismount, remount and run with the bike better I definitely would try it!! I can't believe how fast these bikes are in the woods!
Thanks in advance!!!
