    Is it *dangerous* to use CX tubulars on fast and rough mtb trails?

    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?

    One of the issues with tubulars is the stability of the glue as the rims heat-up from prolonged braking. That may not be an issue unless you have routes with long hills.

    Beyond that, It's mostly an issue of rider skill.

    I would try a clincher 700x35 or 38 (if it will fit) before spending money on new rims and tires.

    I'd say you are no more likely to roll a tubular than you would be in a race, but who wants to mess with a punctured cross tubular in the middle of the woods?

    Either spend that $500 on a cheap mountain bike or run higher pressure/bigger tires.

    Tubulars are awesome for racing though, and IMO that is reason enough to make the switch.

    This! The one time I used my tubulars on a long trail ride I couldn't shake the feeling that I would flat and have to walk out. It's just not worth the risk unless you're willing to carry a spare tub and be prepared for a sketchy ride after mounting it.

    Another option to consider is converting your wheelset to tubeless, which would allow you to run lower pressure and you could carry a tube with you incase you burp or flat.
