ZRACE HARDROCK 2 x 10 /11/12 Speed Road Chainset Chain Wheel crank protector, 50/34T, 165mm/170mm / 172.5mm / 175mm, Cranksets

The reviewer mentions the ZRACE HARDROCK 2 x 10/11/12 Speed Road Chainset as part of the components used in the bike conversion project. They note that it is the same crankset they previously used on their carbon fiber bike, indicating familiarity and trust in the product. The reviewer highlights that while the price has increased since their initial purchase, they chose this crankset for its reliability, especially since the bike is being built for someone else. They also mention the installation process, including the use of a preload retaining bolt with a 10 mm hex head, which differs from Shimano's standard.

The reviewer discusses the ZRACE 2x crankset they purchased from AliExpress for £54. They mention that the chainrings are milled from a single piece of aluminum, which eliminates concerns about screws or bolts coming loose. The only issue encountered was the missing preload screw, which the reviewer suspects may have been their own oversight during assembly rather than a fault with the product. Overall, they report very few issues with the crankset after 3,000 miles of use.
