Reviews & Ratings
18:15The reviewer discusses the LTWOO eGR 1x13s Wireless Electronic Gravel Groupset (2026) as a potential upgrade for their budget gravel bike, noting that it would require changing many components and significantly increase the cost.

15:58The 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.
The LTWOO eGR 1x12s is an electronic gravel groupset with hydraulic disc brakes, using mineral oil and 14500 batteries. It supports 10-12 speeds with an official max cassette size of 46T, though users report compatibility with 50T and even 9-50T cassettes. The MSRP is around 3500 RMB (~$500), but actual prices vary from $300-$650. It includes shifters, rear derailleur, brake calipers, seatpost battery, and cables. Long-term reviews (2+ years, 1000+ miles) are positive, with users praising its reliability, smooth shifting, good brake performance, and excellent ergonomics with taller hoods and adjustable lever reach. However, the newer 2026 version removed magnetic charging, requiring unplugging the rear derailleur cable for charging—seen as a downgrade. Other issues include water ingress in early versions, poor customer support, expensive proprietary charging cables ($50), and non-functional left shifter buttons in 1x setup. A new full wireless 13-speed version has been announced, featuring a fully wireless RD with a 400mAh internal battery, USB-C charging, and new shifters without left shifter buttons. This version is lighter and officially supports 50T cassettes, but the small battery and lack of backward compatibility are concerns. The groupset offers great value but has beta-testing quality and limited updates, with no USB-C charging or major firmware improvements yet.

I have previous experience with L-Twoo groupsets. I much prefer the feel of the eGr shifters compared to the eR9...they have a far more tactile feel to the shift buttons, and the hoods are slightly chunkier (I find eR9 hoods a little too narrow). I went with a 46T max on the rear as that is the max stated capacity of the eGr. I _think_ it could take something bigger, but I don't really feel a need for it...42-46 is a far more generous gear than I'm used to.
