It's 9 months old. As far as I can see there are no obvious scratches and is fully woking. When I took it off the bike I had to remove the remote. I have put it back on and it is still working. You will have to remove it again to fit it and I guess you may have to bleed it but maybe not.
I was going to put it onto my non-stealth frame, dont have the guts to drill or mod it so going to pass it on. In good condition, mail me for pics.
355mm total length
