  • Hey guys
    Didn't find proper information about whats the difference between Suntour Superbe, Sansin and Suzue promax. So there the question - is there any serious difference or thats just branding?

    All different. While Sunshine/Sansin made Suntour Superbe hubs not all Sansin hubs are to the same level as the Superbe. Suzue and Sansin both sold hubs to a number of different quality/price point levels. Both Sansin and Suzue sold hubs with different kinds of bearings. Some were cartridge and some were the superior cup-and-cone (en par with Dura Ace).

  • thanks a lot!
    so Suntour are still the best?

  • after research i got the dura ace ones .. most of the keirin riders uses them so i figured they should be the best..
    if you want to ride your bike in all weather condition i would recommend the gran compe as they seem pretty good!

  • If they are NJS certified then they are the same quality.. Otherwise there is no use for the whole NJS concept.

    As long as you maintain them well you won't feel any difference..

  • gran compe is sealed and dura ace are not..
    NJS is mostly there for stimulating the japanese economics (ever see njs certified stuff not produced in japan? put a side few campa things ).
    japanese stuff is mostly good because they maintain high standards.

    correct me if i'm wrong

    Actually NJS does not mean that they are identical. There are all kinds of possibilites for tuning and tweaking. The differences are not significant but they are measurable in the lab.
    It also does not mean that they are of the same quality. Sugino's 75 track chainrings has the same NJS certification as their Super Zens. One can surely hand-select a Dura-Ace or Sugino 75 chainring to be round enough but even the worst of the production run are NJS. Some NJS products have industrial cartridge bearings and some have cup-and-cone. There are differences. The industrial bearings used might be of a high quality but they are inferior to cup-and-cone in the application. Their only benefit is the ease of their replacement.
    All that NJS says is that a product has been certified by the NJS.

  • I got Dura-Ace and Superbes, I like the the Dura-Ace hubs a bit more but Superbes are really nice also. I haven't ridden Suzue ones, think they make 2 different models of Pro-Max hubs, one that sells for way less than the other. Grand Compe look nice, I don't know much aobut them, but probably on par with a novatec, velocity or similar sealed cartridge bearing hub. Are Grand Compe NJS cert? I would look at NJS export or 8pilgrim8 and phil the power taylor on ebay for good deals on used NJS hubs and other stuff.

  • Suntour Superbe(and Sprint) hubs were made by Sansin. both the cutout flange and solid flange models. I have Sansin 'pro training' double fixed hubs. they have different decals to the superbe model, not as polished either. they spin better than campagnolo record, and measure exactly 120.00mm with my digital calipers at the rear locknuts, very impresive craftsmanship

    Gran Compe njs might possibly be made by an independant small Japanese manufacturer(Dia Compe used to make their own hubs), the Dia Compe sealed hubs are made by Formula.

    suntour superbe brakes were actually made by Dia Compe! superbe cranks were made by Sugino, the seatposts were also made by Sugino.

  • the super zen chainrings do perform better than 75, but are 3 times the cost. its the special coating, not just the roundness. also each tooth is hand filed so that the square edge normally found on the 75 resembles the dura ace 7710.

    as far as I know its ok for racers to do this themselves, some even do it to their cogs and have them chrome/nickel plated

    Yes. A lot of people tune their sprockets and rings. The whole point of the EAI Superstar/Gold, Super Zen etc. is to offer a "read to use" product--- a bit like AMG or BMW-M.
    P.S.: the coatings of choice these days are TiN (Titanium Nitride) and a number of ceramics. I honestly, however, don't see their great utility beyond placebo. A highly polished sprocket and using some special lubricants is hard to improve upon--- why at the Olympics one sees a lot of the top teams using "ordinary" DuraAce.

    I mean specifically Japanese keirin riders.
