agreed...ALL hotrod cranks that i have installed had gray webs and rod with either blue or red o-rings on the bearing
all those black web cranks are the same....and i can prove it...just dont want to call out some of the companys.
that one the guy paid $850 is identical to the $395 TDR CRANK
and for $850 he got to make 10 passes on it before the weld broke and web cracked and when i called the guy he wanted to charge me $350 to fix i,so i sent it to another builder to look at and he said to him it looked to be a defect in the material and it cost around $330 to fix so owner just decided to buy a new TDR crank.
i think after a while TDR will be to number 1 Crank seller once more people realize there spending more elsewhere for the same type of crank
only diference you will find is some builders weld the cranks better and some comes with a TZ BEARING which is something i would not run anymore so !
