Yes, they are!
In the last few years I have run mainly Maguras, which have generally been excellent,, but hard to find service parts for. I've tried Fox, which are so eassy to service but rubbish in use, and I've had one pair of Rebas which came on my Curtlo. They are brilliant! Every part needed to service them is available from TF tuned, anongst others. They have a lovely, easily adjusted action and are pretty stiff. Light too at 1500g for the SLs.
