Ok, well I have been doing some drops around town here, and I was looking at my right crank the other day, and in the spot were the crank connects to the hub, its bent. I can’t take the crank off, but I was wondering…if I replace the hub and crank, is there a certain kind (splined and the others…? I have a bedford off-road 24". Thanks
T.K. just get profile hub and cranks ggggggggggggggeeeeeeeeeeeeeeeezzzzzzzzzzzzzeeeeeeeeeeeeeeee
Hubs fall into one of two categories:
Splined or non splined. In general splined hubs are much stronger and usually have stronger cranks too. They are also far more expensive.
Some standard hub replacement options are as follows:
NON SPLINED
(All hubs listed below use bearings with an outside diameter of 40mm and use Japanese Industry square tapers)
-Standard chrome taiwanese hub Cheap, nasty and easily bent, or sheared through. Flange to flange distance is narrower than others. Crank attaches via nut that screws on to the axle
-Suzue hub. Good quality Japanese hub that ships on unicycles like Miyata. Will stand a fair bit of abuse but still possible to shear through the axle. Crank attaches via nut that screws on to the axle.
-Unicycle.com Chromo hub. Tested as stronger than the suzue hub. Crank attaches via bolt that screws into the axle.
If you go with any of the above replacements you will need to find some good cranks. These tend to be very expensive and still likely to break. Aluminium cranks usually last the longest but have a tendency to need continuous tightening. Kooka make some good cranks for tapered axles.
SPLINED (generally more splines = better)
-Profile hub, 48 splined hub made by profile racing. Uses 40mm or 42mm bearings. Recognized as virtually bomb proof. Very good quality but very expensive. They come with a lifetime warranty. Good choice of crank lengths too.
-KH/Onza hub, a new hub (32 or 36 spline I think) resulting from a collaboration between Kris Holm, Onza and with input from Roger Davies. This could be the new standard in unicycle hubs and may be an improvement on Profile.
-Onza hub (old style). 36 spline hub made by onza. Some early versions had problems with slop. Long since sorted out I believe. Uses 42mm bearings.
-KH hub (old style). 8 splines and uses 42mm bearings. Is has been the standard on KH unicycles until now. Again a number have had axle slop problems. This can be fixed and their are plenty of threads on how to do so on rsu.
-QuaX, German brand with 10 splines. Ships as standard on their offroad unicycles.
Here is the latest specs on the KH-Onza crankset:
Redesigned for 2005, the KH-Onza crankset is both stronger and lighter weight than its predecessors. Product details:
Cranks: High strength, oversize CrMo tubing, 1/2” Q-factor (outwards flare). High precision press-fit onto 36 spline axle, secured with an ingenious new end-bolt split-washer combination that eliminates creaking.
Hub: Hub flanges are CNC machined 7000 series aluminum, carefully shaped to maximize wheel strength. Each flange is machined separately and press-fit onto a 20mm CrMo splined axle with the same high strength spline interface used for the cranks. This new design approach increases durability while reducing weight by removing unnecessary metal from the center of the hub.
lower weight but increased price:(
