Created: December 27, 2025The reviewer discusses an AliExpress carbon seat post purchased to achieve a zero-offset fit and save weight on their BMC hill climb bike.

- Provides a zero-offset design which improves bike fit for the reviewer
- Overall fit and finish is described as 'really good'
- Has height markers for easy adjustment
Cons
- Expensive for an AliExpress part (around Β£90)

CrankBigrock Carbon Crank162.5/165/167.5/170/172.5/175 Cycling Parts 354g Bicycle Crankset For BCD 110 Axis 24mm For Sram Cranks
Created: August 14, 2025The reviewer installs and tests the Bigrock RS carbon crankset from AliExpress as a potential weight-saving and bike-fit upgrade. They compare it to their existing SRAM Red GXP crankset.
AI-Summary
Pros
- Saves approximately 20 grams compared to the SRAM Red GXP crankset
- Uses a titanium axle for reduced weight

Key Points
- Brand is Big Rock (RS)
- Standard 24mm axle
- Includes titanium axle and all mounting hardware
- Weighs 454.7g with spider, chainring, and bolts (compared to 475g for the SRAM setup)
- Primary motivation for the swap was improved compatibility for 1x setups, not just weight savings
ScrewsDropout 57 For BMC No57 Teammachine SLR01 02 Rim Brake MY20 ALR Derailleur Hanger 301091 (Shimano-direct-mount)
Created: December 27, 2025The reviewer tests a 2020 model direct mount derailleur hanger from AliExpress on their 2014 BMC Teammachine to see if it is compatible. They note it looks identical in shape and fits perfectly, potentially improving shift quality and saving weight.
AI-Summary
Pros
- Fits perfectly on the older frame
- Saves 12 grams of weight
- Potentially improves shift quality
- Seamless integration with the dropout
Cons
- It is not the officially designated part for the 2014 bike, so compatibility was a risk
- The reviewer was concerned the angle might be incorrect (though it worked)
Key Points
- The hanger is for a BMC Teammachine SLR01/02 Rim Brake MY20 (model 301091)
- It is a Shimano direct-mount hanger
- The reviewer used it on a 2014 BMC frame successfully
- Weight: 15.1g for the new hanger vs. 28.6g for the old hanger and b-link combined
