Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

suzue promax njs

i just bought a pair, i noticed that there is a lil rattling or clicking sound when spin them by hand, could this be due to a slight binding or lack of grease? other wise these hubs are superb!

if you try to jerk the axle up and down and get a bit of knocking.
just tighten up the cups.

I have the same problem with mine (28 hole, so not technically NJS). I overhauled them, but it didn't make it any better. Some people love these hubs though, suggesting that perhaps its an issue of poor quality control.

Promax tried to be in the middle between formula/surly and phil/campy/DA, but IMHO, they are the worst of both worlds.

Are your hubs the promax SB hubs or the juniors. I believe there is a difference in quality.

Just out of interest how do you know its missing two ball bearings? Do you have the Suzue spec sheet? Do you know how many bearings it should have on each side?

Keep inserting balls until one is forced out and remove the last two. Magic!

The way to know how many bearings go in a hub is by the process I just explained. Remove the last two balls when one is forced out. This obviously assumes you have access to extra bearings of the proper diameter.

Umm..there are about 5 different bearings sizes. I doubt the bearings in your bb are the same size as in the hub. Generally, BB bearings are a bit larger.

What 12XU is trying to tell you is that you should NOT have a solid ring of bearings on the inside of your hub. There is *supposed* to be a space (generally the size of 2 or 3 bearings) so that the bearings that are there can do their job, rather than binding up and trashing your hub.

That's why I chalk it up to poor quality control.

Not a fan of suzue.

after working on these hubs for better than 3 hours to find that sweet spot, i discoverd that the races in the rear hub are not perfectly round so that when the hubs spins ever so slightly,the axle scraping the poorly machined bore that the axle goes through. i took the axle out cleaned everthing, then ran some emery cloth through it to reduce burrs. I then repacked cups using( super lube) grease, this imo is D best lube. now its smooth and ready to be married to rims.
