I do not own an MTB and have been using my CX bike for trail riding. Most trails in my area are hard pack with some roots and a few rock gardens.
- I have been running 60psi on 700x33 clinchers with no flats on MTB trails.
- I run 45 psi during cx races with no issues.
- I dismount and run the big rock gardens when riding mtb trails.
- I tried riding at 45psi on the mtb trails and although it felt 1000000 times more awesome I got a pinch flat.
I can switch to a tubular setup for under $500 which would be great for racing but I am not sure how it would hold up to riding my local mtb trails. There are very fast downhill rutted sections that I fear could roll a tubular off the rim but I have never used tubulars before so I need your opinions. Can I use 700x33 tubulars at 40psi to cure my pinch flats while trail riding or is that dangerous?
