Very happy with my Crossmax Elites, 650b boost version. Tyres are definitely summery light, some others are on order, but that’s not to say they aren’t good for the intended purpose.
I haven’t put many miles on them, and I right pretty light too, but they feel very well put together.
Mine came with tubes installed, but with every thing included to go tubeless. Set-up to tubeless was a doddle though, no faffing around. Just needed to pop out the tubes, in with the T/L valves and the Mavic juice, then just pumped them with a track pump. I felt almost dissatisfied that it was all so easy, no heroic tale of hours of messing around.
