LTWOO Finally Went Fully Wireless. Was It Worth The Wait?

The reviewer purchased the LTWOO eGR 1x13 (2026) groupset from AliExpress and tested it on a gravel bike. They found it to be a budget-friendly wireless groupset with some compromises in build quality and cassette compatibility, but praised its ease of installation, brake performance, and value for money.

AI Summary

Pros

True wireless system makes installation easy
Brakes are a big step up, lightweight monoblock calipers, pre-filled and work well out of the box
Mineral oil brakes are easier to handle than DOT fluid
Shifters feel premium with good ergonomics and no rattling
Lighter than SRAM eTap (1102.6 g vs 1217.8 g)
App allows manual tuning of each sprocket, useful for cheap cassettes
USB-C charging port replaces proprietary chargers
Price around £250 with coupon code, offering good value
Comes with standard flat mount brake calipers and Shimano-style adapter plates

Cons

Only compatible with a 46-tooth max sprocket; cannot handle a 50-tooth cassette
Rear mech build quality feels cheap, especially the charging port flap and plastics
Left shifter has a cutout where buttons would be, feels cheap with sharp edges
Clutch on rear mech is not the most powerful and feels linear
Overall fit and finish is a step down from the road version (ERX)
Not confident in water ingress protection of the charging port cover
Pulleys are not ceramic bearings and feel standard
