Created: December 27, 2025The reviewer discusses the OG Evkin carbon outfront computer mount as a weight-saving upgrade for their Garmin mount.

They also appreciate the included action camera mount.
AI-Summary
Pros

CrankBigrock Carbon Crank 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
- Uses a standard SRAM 3-bolt mounting interface, which is better for 1x setups and chainline adjustment than the hidden bolt design on the old SRAM cranks
- Full carbon crank arms
Cons
- The weight saving is described as 'not massively lighter' and 'not groundbreaking'

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)
