The Carbon Speed 24mm titanium spindle carbon crankset is a lightweight aftermarket option praised for its low weight (~320-330g for arms), clean logo-free appearance, and Shimano-compatible 24mm spindle. However, it suffers from chainring quality and compatibility issues (especially with Shimano 12-speed quick links), limited power meter interface options, and installation quirks. Price varies by source ($310-$340), and crank arm length options are limited to 155/165/170mm.
Pros
- Lightweight: ~320-330g for 24mm titanium version, saving about 220g compared to Shimano 105 alloy cranks (565g); complete setup with power meter (647.3g) is lighter than Cybrei equivalent (688g).123
- 24mm titanium spindle for Shimano compatibility, with titanium being lighter and stronger than alloy.1
- Available in multiple crank lengths (155mm, 165mm, 170mm) and spindle options (24mm titanium, 29mm DUB aluminum) for different frames and preferences.13
- Compatible with Easton-style power meters (XCadey, Sigeyi) and offers flexibility for chainring setups.3
- Clean, logo-free carbon finish appreciated for aesthetics; in-house design, not a generic rebrand.21
- Includes nice details like pre-applied thread lock and spacers.1
- Offers weight savings at a lower price than some alternatives (e.g., $310 vs higher-priced brands).3
Cons
- Chainring quality issues: wobble, misalignment, and incompatibility with Shimano 12-speed quick links (and ZTTO), causing poor shifting and setup difficulties; aftermarket chainrings like Alugear may be needed.32
- Limited power meter interface: no 3-bolt or 8-bolt options; not compatible with Magene P505; only Easton-style (XCadey, Sigeyi).3
- Installation challenges: BB compression when over-torquing, unclear torque settings, and spacer issues requiring careful setup.3
- Plastic preload ring on some versions may be a durability concern.3
- Limited crank arm length options: no 172.5mm or 150mm.1
- Higher price than some AliExpress alternatives, though it offers weight savings.3
- Price is higher than the 29mm alloy spindle version.1
