Someone was asking, and I thought it was a good question, is there a non-Enduro "6901 SM Max" choice for aftermarket? This appears to not be a standard 6901, but 12.7ID instead of 12.0 and has a "hat/lip" on the inner race that protrudes further than the bearing. It's the "SM" part. In other words, it looks to be proprietary to Enduro/GG. Can GG confirm or is there an equivalent designation for this bearing in the industrial bearing market or non-Enduro option?

Planning to change my bearings this winter, so interested to know.

Enduro is the only company I know about that sells those. The longevity on those is pretty good, they typically outlive the rest of the bearings in the frame, fwiw.

I'm confused. So is Revved a separate company from GG?

I just assumed "revved" was what GG called their crabon frame manufacturing process.

it started that way but then they set up revved industries as a parent company that owns the IP. or something along those lines.

And revved trying to do aerospace work iirc. So it's probably like colt splitting their pistol and rifle business into separate companies so they only needed to get rifles ISO compliant to get us gov contacts.

Funny how we've basically went back to the same air shock idea...I remember when even XC bikes came with good old coils. And they were supple.

You should add a weight weenies trigger warning when posting stuff like that!
Why? An AMP B5 with F4 fork (both coil) is probably still lighter than any modern XC bike. How long it lasts is another story, but that is not important to a weight weenie anyway. :D

A buddy of mine had and AMP with linkage fork and I had the Mongoose Amplifier (their licenced version). Both bikes used plastic bushings instead of bearings or sintered bushings. and both were easily the flexiest bikes I've ridden.

You clearly never rode early generations of titanium frames. Front derailleur chain rub and crankset touching stays under sprinting was common. Thankfully square taper BBs made it possible to space the cranks out enough to make it work. :sarcastic:
The few times I test rode it, I always liked the F4 fork. Still looking for one with carbon legs to throw on a retro build.

So my cane creek DH inline air broke on my trail pistol. It feels like the damper rod broke or came disconnected from the piston, it has basically no rebound damping and on rapid hits has no compression falling for the beginning of the travel. Guess that explains the weird noise the bike has been making.
I wasn’t very happy with it to begin with, I was running 18% sag, a full volume spacer, and the hsc 1/2 turn from full closed. And it was still blowing through the travel pretty easy on big hits, but not that but since the dvo saphire fork at 30% sag no volume spacers and the hsc 1click from full open performs as I’d like. Also I can’t find a mix of rebound settings that feel good pumping, don’t try to ejector seat me on jumps, and track well on rapid bumps down hill. It actually felt the best in the case on the ride that it broke, ha.

I’m thinking I should replace it with a coil, maybe pick up a used super deluxe ultimate and have it avalanched. Is there a spring rate chart or calculation for the frame?
