I have just easily put on some Crossmarks that came with my bike I got last year that I had forgot I had. I took them off because they were very sticky tyres and on the road it felt like I was riding through treacle.
I got the Conti’s because I occasionally use my bike for chaingangs, (and just recently a 100m sportive) and its at least 10 miles on the road before my rides take me to my off road play land, so thats why I want fast rolling tyres.
Most of the trails I am on are dirt/gravel (Pentlands/Lammermuirs) and occasionally grassy sections.
I’ll put grippy tyres on my other wheels I have replaced with the Crests for winter and crappy weather, Im really just wanting fast and easy fitting for the Crests.
I don’t need new levers, I have had my fair share of tight tyres/rims in the past and have had to change my tyre choice because of this!
