New crank RED, SLK or other
I want to change my crank from 172.5 to 170 on my SuperSix EVO Red 2012. It currently has its original SRAM Red (I think black edition, although its silver/grey). This is an opertunity to get a better and if I am it should be a lighter crank. What people's opinions and experience, I know the Holowgram is the ultimate, but its very expensive at £600 and needs new bearings as I think the spindle is a different size, so looks fraught with complications. The newer SRAM Red Exogram I thought would be a simple change and save weight and currently can be had on sale for less than £300, but its designed with Yaw auto trim, so ideally needs new derailleur and shifters, although i think i could get away with just crank and derailleur, but again adds expense and complications. Would an FSA SLK (£200-250) be a simple swap and save weight? Also is the KForce (simular price to SLK) much better than the SLK? I prefer the look of the SLK to be honest and am not 100% sure, the KForce is that much lighter?!? Any thoughts or experience?
