Shimano 9 speed rear disc hub, 135mm 36h

Postby BTP » 8 Jan 2020, 3:53am

Hello,

I'm trying to obtain a Shimano 135mm 36h rear hub, disc compatible, for touring.

I seem to remember reading somewhere that Shimano moved away at some point from steel axles to aluminium alloy versions which weren't so reliable for touring. If so, I'd like to try and source the steel axle version. Does anyone know what model number this would be?

The reason for 9 speed is that I bought a stock of 8 speed cassettes that will last me a few years and, with a shim, will fit the 9 speed hub I believe?

Any replies gratefully received - many thanks in advance.

Tony

I too have heard stories about the alloy axles and their weaker bearings, but I am a heavyish rider and I have used them without problems.

Deore - FH-M525
XT - FH-M756

No need for a spacer to use an 8 speed cassette with those hubs (8, 9 and 10 speed cassettes are the same width).

Thanks for all replies.

From other threads, looks as though the Deore FH-M525 is a good option provided the bearings are repacked with grease after purchase and before riding. I'll give that a go.

Cheers
