"Anyone know who does the warranty work?"
Send it back to whoever you bought it off, your contract is with them. They'll send it to 2Pure
I could be wrong but when I looked CRC only had 75mm drop Crank Bro.s ones, which isn't exactly a lot
My 125mm drop KindShock/Purerace one is much more useful, actually dropping right out of the way for 99% of the time I drop the saddle.
Okay so a lot of the time I might only drop the saddle 30 – 80mm (ish) but being to drop further when required without having to stop, get off, drop it, get back on, try and set off on in a dodgy spot is great
I bought one because even with a conventional seatpost chopped so that its at minimum insertion at pedalling height, I can only get the saddle about 80mm lower when dropped, I was wanting a bit more for silly sections where the saddle was getting in the way fully dropped
