GOLDIX XDR 12 Speed Cassette 28T 33T 36T Ultralight K7 Cassette 12V for Sram XDR Electronic Shifting r9270 r8170
CassetteI've been running Goldix cassettes for the last year on several bikes and haven't had any problems with shifting, noise or durability so far. I've now got 2 x 10-36, 2 x 10-33 and have recently added a 12-speed 10-44, which also seems to work flawlessly. I also bought 10-36 and 10-33 Zrace cassettes in 2024 but the shifting is hesitant in some cogs which is not the case the Goldix ones. I'm still using Red cassettes on my best bikes, but these Goldix cassettes are about equal on weight and are proving to be great value for money.

LocksThese ones are fine - I have 1431 miles (2300 km) on them. The only issue is when I tried to take the spindle off of the right pedal body, it was on very very very tight. I was unsuccessful, so I'll have to go to more extreme measures when I need to service. So that's a bummer.

Bigrock Carbon Crank 24mm For Sram Cranks
Crank
The reviewer mentions the Bigrock cranks as an upgrade installed in a previous video (part one). They state that the cranks were installed with their stock spider and a 4-bolt chainring, which was light but didn't save much weight versus their previous SRAM Red crankset.

- Set up to work with 3-bolt SRAM direct mount chainrings, enabling a lighter chainring upgrade.
