XT Deore M750 Crankset-Head Scratch

[trezize]

Am I going insane?
I am looking at a set of XT FC-M750 cranks that recently arrived and I am seeing a square taper fitting?
But I thought these cranks had a Octalink V2 fitting? Didn't they?
Did some early production have square taper?
Did someone machine out the Octalink to allow a square taper fit? Am I loosing it?

Please help. Thanks

Same typeface, same paint scheme, same spider, and when new, same chainrings.

Xt fc-m750, square taper.

Xt fc-m752 octolink:
Of course either if these could be found on an xt m75* groupset.
It's very unusual for shimano to change just the last digit of a 3 digit product code without it just being colour or another smallish detail.

There was a m751 in the middle too. Octalink bb.

Thanks guys. I think I was misinformed about the M750. The information I was referencing didn't break down the M751, M752 variations.

I am happy the M750 square tapers I have are legitimate as they seem to be very nice cranks.

My Coyote is running square taper M750 cranks.

Thread 'Coyote DH'

Dec 2, 2020

To get the ball rolling, here's a quick introduction to my 1999(?) Coyote DH.

Purchased brand new back in 1999 from Super Cycles in Nottingham, it's been a stalwart of the fleet ever since. Although it's spent most of it's life in Norfolk, it's been to Wales and the Lake District over the years amongst other places.

The build has gradually evolved over time, rather than ever being stripped and rebuilt like some bikes. Just had an overhaul after not being used for several years after the brakes packed up. These photos show the bike as it was in 2011.

More pics and recent updates to follow.

The lx and xt square taper cranks of that period were famous for rounding out.

Maybe shimano made them less substantial as octalink was going to be the new quality standard,
or maybe suspension and geometry evolution was getting more and more riders into the air.

Fit them well and check Torque from time to time
