Shimano M640 Zee Front Hub

Shimano Zee M640 Front Hub

Ripping down the peak demands durability and reliability when it comes to hubsets. The new Zee hubs are extra tough, smooth running hubs to provide a huge advantage when you’re bombing down the artery-like trail systems at the local mountain bike park. With quality sealing and adjustable angular contact bearings, the Zee hubs also spin on extra stiff, one piece rear axles with integrated cone construction. Throw the Zee front hub on any modern gravity build for bomproof performance from the top of the lift to the bottom of the mountain!

  • Adjustable cup & cone angular contact bearings
  • 20mm thru axle only
  • Hub Drilling: 32 or 36
  • Spoke Type: J-Bend
  • Hub/Brake Compatibility: Center-Lock Disc

POSitively not good
I thought this 20mm hub would be a robust upgrade from my SLX 9mm quick release. I bought it to go with my new Fox 36mm fork, which is unbelievably good.

I thought this hub would be downhill capable, and I was right, it was only capable of "going downhill" quickly.

Within a couple of months the bearings started going bad. Apparently, the bearings were somehow tightening up on their own. They were acting as a secondary brake and it was a real drag. I am fairly certain I did nothing to cause this failure.

After realizing what was going on, I took the hub apart and the races were badly worn and pitted. It was irreparable and I had to replace it.

I was happy that Jenson gave me credit for the bad hub, but I had to eat the cost of rebuilding the wheel.

I replaced the POSer Zee hub with a Hope Pro 2 Evo 20mm cartridge bearing hub and it has been perfect. I have high hopes for the Hope and you should have low expectations for the Zee.

Really smooth needed a 20mm for a pike fork for the price and center lock couldn't find anything else to compare.
