barbarossa said:Hi,
just want to share some more experience with my AM1000. After all i am very happy with my bike. most of the problems or issues are mentioned in the thread. and i knew what i would buy and i like DIY bikes . additionally i want to share an issue that might be very risky.
my bolts of rear suspension were too short (upper: 2mm / lower 2.5mm). you can remove the both right screws. or you can check it using an allen key and spin the left screws clockwise - there shouldnt be any noise and spinning should be smooth and without using much power (no side pressure).
but exactly this was not the case. so i removed the rear suspension.
for the upper bolt i could use a 2mm washer (6mm inner / 8mm outer diameter) because the bolt (65mm) was long enough to cover/fill the 2 inner rings of the ball bearings. Only to avoid side pressure i had to use an additional washer. bolt axle should move free without any pressure. optimal length would be around 67 mm, but i did not find that length and i did not want to shorten a longer bolt.
the lower bolt did not fill the ball bearing inner ring at the right side. bolt is appr. 39mm which is too short - i needed 41mm. so i now use a 44mm bolt with 3x DIN-1mm-gab washer. so i have exactly 41mm. the short bolt damaged the 2 ball bearings - right inner ring was split in 2 halves (but i did not recognize it - rear suspension did not made any noise and still worked) - left ball bearing was not spinning smooth anymore. i had to replace the 2 lower ball bearings (SKF 8x16x5mm 628/8-2RS1).
perhaps this issue might also damage the rear suspension attachment itself.
i have the rear suspension attachment in attached picture...

I've been poking around looking at tires too, The Maxxis Grifter in a 29x2.5 looks like a nice option, it's not available in a 27.5+, I might need to ask about a second wheelset. :lol:

Hi Folks found this post and figured Id post. I have the same bike but I purchased mine from Biktrix in Canada. Im located in Denver. I wanted to mention that I have the Grifters on my Ultra and they do work awesome. I have the 29er wheels and hardtail with Wren front suspension.
Are they actually building the frame themselves? Seeing similar designs from china. Just curious why their frame looks so weirdCruncher123 said:jwt355 said:Richard N said:I have a few new pictures from Ivy, no new info yet.

Not the same bike. Frey builds higher spec bike with different geometry.
