I’ve just recently got a Trabec Race to replace my Giro Xar.
It’s the first non Giro helmet I’ve found that actually fits on my huge, oddly shaped melon. Seems very well made, much better than recent Giro’s, the fit is definitely better, my head seems to fit in the helmet rather than the helmet fitting ‘on’ my head.
Retention strap isn’t as clever as the RocLoc but I find that I set it to the right tension and then forget all about it.
Venting is far better than it looks like it should be. Seem to remember Giro banging on about the Xen venting being specific to the lower speeds of off road riding, same principle here and it seems to work.
If it’s heavier it’s not so much that I’ve noticed.
SO to sum up my rambling. I’m well happy with it. 🙂
