Shimano Deore FC-M612 175mm Replacement

[Deleted member 26715]

Still issue with my Shimano crank, non drive/left side, doesn't look like I can get a M612 anymore, what is a suitable replacement crankarm?

Helicoil maybe possible, but what's the chances of getting 10MM Left handed threaded one?

Oh dear. Any crank in that length. Seem to remember SJS have a selection of LH cranks.

Thank so such as this would do? https://www.ebay.co.uk/itm/Shimano-...676941?hash=item23f276080d:g:5YwAAOSwVnpgXw0f

Nope, that's a Octalink, you need a Hollowtech chainset.

You won't get an exact match. This would be close in black and 175mm:

How about this? https://www.decathlon.co.uk/p/doubl...at0DJS7Qp5VSMMdsMjocRp7dRSTTvdxhoCWrIQAvD_BwE

That would work if you have a 9 speed. Is yours a double? But you could just use the LH.

The eBay one would work too but doesn’t specify length.

Wasn't thinking of using it all just the left crank arm at that price, mines a 10sp triple. https://www.cube.eu/en/2016/mtb-hardtail/attention/cube-attention-sl-greynflashred-2016/

Left only would be fine. You could even put right hand side on eBay.

Delivery isn't for about 10 days, is this an alternative https://www.ebay.co.uk/itm/Shimano-...798333?hash=item422d4c053d:g:yKsAAOSwH4xgWPNn

 

[Cycleops]

That would be okay. Not exactly in good condition but you can always spray it.
