Shimano105 FC-R7100 12-Speed Crankset (Return to Product Page)

Bike shop said my recalled Ultegra crank did not have cracks, so they could not replace under warranty, but also said it could break any time. This did not instill me with confidence. So I bought this crank at BTD and replaced it myself. Easy and only a minor tweak required of the derailleur on my 2x11 speed. This one feels more solid when I stomp on it and I don't have to be wondering if it going to suddenly blow apart under me. The weight difference has not slowed me down. I did wait for a sale to buy this one, and it was a bargain!

I recently purchased a bike with 105 di2, but it came with a Shimano non-series crankset. I replaced the crankset with the 105 7100 before riding the bike because I knew that detail would bug me forever. Compared to the older gen 105 cranks, these are more angular and modern in appearance. From a distance, they look identical to the new Ultegra and Dura Ace cranks. Other than that, these aren't too heavy and aren't too expensive - what you expect from 105 components.

This worked well as a replacement for the damaged cranks (and a slight upgrade) on my endurance bike. Installation was really straightforward and the price seemed reasonable.

I had been using a Dura Ace 9100 crank but recent history of DA and Ultegra cranks breaking caused me to downgrade to 105. So far, I am very happy with this 105 crank. It works with 10spd chain, shifts as good as DA. The big knock about 105 is that small parts tend to break off. No small parts on the crnks. The only caution is that chainrings are not backward-compatible. You need to use current chainrings due to crank shape at spider.
