I just ordered mine. In a few weeks we know better.
On my modification of the DengFu E10 eMTB with a 4-bar w/ shock linkage design there were 2 critical points.
- Bridge of seat stay (if there is one limiting) touching the seat post from behind if compression too long. As 210-55 < 213-63 by 5mm it could be an issue. With 2x2mm offset bushings we are coming very close to the original compressed eye-to-eye distance.
Tire clearance to seat tube is no factor in Mullet setup. - Increased length of shock too big to fit into the eye-to-eye distance w/o the yoke touching the seat post from front side.
Corrective action: offset bushing of 1x 2mm and taking 1mm off the yoke (now 1,5mm yoke-to-seat post clearance)
On AM831 frame shock length fully compressed no issue as longer as standard 210x55. Fully extended maybe (if someone with the frame could take the number, please), then 1 or 2 offset bushings could do the job.
The following numbers are from Linkage X3 based on the SC Hightower which has identical spec data w/o an error message that it would exceed the frame limits. But please do not rely on me making fancy adjustments.
With an 3mm longer shock length it's ~0.4-0.5° steeper HA, but no change in SA on New AM831.
584mm folk (~170mm for a Mezzer PRO) ~1.3° slacker HA.
Mullet with 2.5" wheels ~ 0.9-1.0° slacker HA and a BB drop ~6.7mm higher
As a result: 213x63 shock, plus 170mm folk plus Mullet setup will end around 64° HA which is a modern Enduro HA and of cause also slackening the SA by 2° in total which is not so sweet.
Rumours say that SC has only one basic frame design and they produce a Hightower, Megatower, Nomad, Bronson out if it. How about the new Bromadtower then
