As for the lefty.. 1st time I got on a lefty equipped bike I pushed off, looked down at the headstock, and fell off.
After that it was fine, I’ve ended up with two of them!
There very stiff, I thought noticeably so, when swapping between it and my QR equiped bike. My main one was serviced after I bought it, and went 2/3 years without any intervention, other than the occasional bearing reset.
Had it upgraded (damper) last year (and still not fitted it!) and all the internal bits needed no replacement parts.
I had the SPV version and found the damping left a bit to be desired, and had tried a TPC version previously on a demo and thought that the better pf the two (rose tinted glasses?). The basic damping was the reason I had it upgrade (and cause I could)
Oh and yes you can just about take both hands of the bars, but I never managed a danger panda shot while riding it.
