Product Description
VERY rare Canadian made TNT Performance Products Hard Drive Series crank, vintage mid to late 1990's! The HDS model was aimed at DH racing, or heavy/strong riders. It has a solid "dome" shape flange to fit the spider, vs the Light Drive Series (LDS) which had a 6-lobed spider flange. This is the second generation, which had a more nuanced shape to the tapers among other changes to prevent cracking.
Condition
These are in exceptional show bike worthy condition. These have extremely few miles on them. The tapers have installation marks in them so they've at least been mounted. There is zero ano wear from chainrings or chainring bolts, supporting very few lightly ridden miles. Spider is mint. Arm ends are scuff free and almost perfect. Arms themselves are very nice with only a few imperfections. Slightest touch of heel rub a couple inches from the taper side start of the tapers (I missed these in my physical inspection and noticed them in the photos blown up). The drive arm has a zig zag scratch on one side, the non-drive arm has an even lighter scratched area on the side, and the non-drive arm has some marks on the taper side end. Some microscratching in the polish. Absolutely zero cracks
