- Actual capacity of a Zee M640 mech
My kids are riding with M640 Zee wide ratio mechs, which claim they can handle up to a 36t cassette. Does anyone know if that’s realistic or how much bigger a cassette I can use? The sunrace 10-speed 11-42 looks mighty tempting.Posted 8 months ago
I had one running on 11-42. Longer B screw. Depends on frame/hanger design.Posted 8 months ago
Great, thanks. Might experiment with the 11-42 on my wheels. Where does one buy longer B-screws?Posted 8 months ago
40T is overstretched without a longer b screw, trust me I know, I learnt the hard way as it exploded and had to singlespeed home.Posted 8 months ago

zee +40t wouldnt work on my single pivot empire due to chain growth.
zee + 42T worked fine on the HT.
so it depends on teh frame n stuff.Posted 8 months ago
36t is a realistic limit for Zee, in my experience. The new Deore mech is cheap if you want to go larger.Posted 8 months ago
Ah yes, the M6000-GS. 10-speed, 42t top, and clutch. Now the boy is on 26″ wheels having a tiny mech is less of a concern.Posted 8 months ago
Mine works on a 42 with normal b screw, full sus frame and shifting is pretty good.Posted 8 months ago
ZEE is for sending, leave the flappy long chain at homePosted 8 months ago
I have a similar experience to kelvin, in that I couldn’t get the zee to work with anything bigger than 36. Switched the cage for a oneup RadR cage and now works happily with a 42. They’re like hens teeth to get hold of these days though.Posted 8 months ago
