Can you service an octalink bottom bracket?
Can you service an octalink bottom bracket?

What is an octalink bottom bracket?
Octalink Bottom Brackets. This system, designed by Shimano, was the first successful alternative to the older square taper. The Octalink system uses a larger and stiffer spindle with eight splines. The splines provide a greater contact area between crank and spindle for a stiffer interface.
Is octalink better than square taper?
The octalink is most likely stiffer than square taper, bringing more sense or feel of power transfer and traction. Generally smaller rings for sit and spin, bigger rings for stand and mash. The common 22, 32, 44 triple rings cover both styles of riding well.
Is octalink and Isis the same?
Octalink lasts a lot longer because of their application of bearings, but Isis should provide better power transfer because it has more splines. And since it also has more splines, the actual interface between the BB and the crank should also be stronger.
How often should you change your bottom bracket?
Every three months or so I’ll take the cranks out and if it’s a threaded bb, I’ll remove the bb and do the full service. Around the three month mark is normally enough time, even in the best conditions for dirt to work its way into the small gaps and contact points around the crankset and bottom bracket area.
How many miles should a bottom bracket last?
As for a bottom bracket, on the low end, maybe 5000 miles. The basic Shimano one most people use (UN51/55/similar) can reasonably expect 10k+ miles. But sometimes you get unlucky and get a bottom bracket that lasts maybe 500 miles.
Is Shimano octalink any good?
Octalink and ISIS splines work very well in terms of securing crank arms, and tend to be cheaper to boot. In my mind, if you can get a good deal on something, run with it, rather than worrying about what you have or what to get.
Can I upgrade my bottom bracket?
Usually if both chainrings and the bottom bracket are worn out, you might as well upgrade to the new setup rather than buy all the parts for your old unit. Besides getting something that matches the rest of the parts, you’ll know you’re hammering on brand-new crankarms, too.
