I have always owed XC race bikes hardtail( now gone) and a 3" race bike and use the race tires that go with them. I parted out the hardtail becauce my 3" travel race bike pedals so great I never rode the hardtail anymore. I am just finishing a 5"x 5" bike and looking for a larger tire maybe a 2.35 with a resonable weight ~ < 650 grams to run in the front range, The biggest tire I have run in the past is a 2.25 nobby Nic and a Michelin 2.2 ALL Mountain any thoughts?? Thanks !!
