Had my second ride with FTD tire insert on the rear of my plus size hardtail and all i have to say is WOW! My favorite trails consist of rocks and roots that most would want a full suspension bike for.TheĀ half of pound it adds is a amazing upgrade I’ll let you know. It doesn’t make the bike bullet proof as I was still able to ping a rim BUT it certainly puts you on a different level. The ride is so much better as the sidewalls are stiff and it takes the bounce out of the rough stuff as well. For the worrying about what your about to crush , well lets say if your good on a hardtail it gives you the catch me if you can mentality. Equally as good for bombing climbs that are rim bangers. Line choice as always is still important its just a new level of fun and trust me, the people on full sus will be talking when your pulling on them or catching them. Cant imagine what it would do on a full sus. I would guess and say your are bulletproof.
