Interested to know how old these cranks are, I've got an early set without the grooves in the the top edges
What year were race face turbine cranks first produced?

Re:
That's forged so it's a later set, mid to late 90s without looking in detail.
The early LP 1994 ones where CNC and a bit heavier and wider lower profile looking. (A bit beefier looking).
Before that in 1993 there was just the IB version.
Iirc 1995 they introduced the forged then CNC versions and the compact version size
But I think 1996 is when they thinned them down.
The edges went in the 00s with ISIS setups I believe (ignoring the DH versions)

Re:
Ahh well the original ones look newer to me, mine are square taper and 94pcd if that differs at all

Re:
The originals from 1993 had the separate spider and were 110bcd
The later ones used a once piece crank, 94bcd and were low profile, like your ones (which were the nicest as they tended not to creak or crack)

Re:
No they are IB (I-Beam) not LP (Low Profile). Both are different lines and ran side by side once the LP was introduced a year after the IB hit the market.
Both are Turbines of course, both came in Compact and Standard once introduced too.
IBs also had a road version too.

Re:
The one without holes have a deeper front crank arm profiling and a rounder seperared style for the spindle centre rather than straight edged from the crank arms.
They're the ISIS era cranks (still with square taper too) so whenever they brought them out in the 00s given they where a pioneer of it.
There are some catalogues in the archive, though I don't think the pictures are quite correct for the years. Description is there and we have English versions too in the catalogue forum section. After that you can hit way back machine.
