LTWOO eGR 1x13s Wireless Electronic Gravel Groupset (2026)

Replacement charging cables are available from 80 Design store or AliExpress for $20-50, but they are proprietary and expensive. Some users recommend external chargers for 14500 batteries as an alternative.

The new eGR v2 can be found for as low as $287 shipped after coupons on AliExpress, though prices vary and some regions show over $400. Coupons can significantly reduce the price.

Hood length from top to palm area is about 11cm, top to lever tip is about 17cm, and lever tip to bars is about 11cm. Users report better ergonomics than Wheeltop GeX, with taller hoods and superior brake lever reach adjustment.

Officially 46T, but many users successfully use 50T cassettes with B-screw adjustment, though shifting may be less optimal. The new eGR v2 officially supports up to 50T and works with 10-51T cassettes (including Shimano M8100) and 10-45T without chain shortening.

No, the left shifter buttons are currently non-functional in 1x setup. LTWOO has considered adding configuration options but no update yet.

No, LTWOO uses a proprietary 70mm flat mount design. Adapters are included for 140mm and 160mm rotors, but post-mount frames require Shimano-compatible calipers.

Yes, eGR rear derailleur can pair with eRX shifters and front derailleur using a dual-port battery, allowing 2x setups, though this is not officially supported.

Yes, it supports 10-46t cassettes and users report success with 9-46t, 9-50t, and 11-50t cassettes by adjusting the high limit screw.

According to 80 Designer Store, old eGR RDs may be able to get a 13-speed firmware upgrade via the app, but it is not recommended due to different cage design risking spoke contact. New shifters are not compatible with old RD, so upgrading requires replacing both shifter and RD.

Yes, LTWOO brake calipers can be swapped with Shimano mineral oil calipers. SRAM uses DOT fluid and is not compatible. Users have successfully used Shimano XT calipers with eGR levers.

Yes, users report that the new eGR v2 works with 10-51T cassettes, including Shimano M8100 10-51, and also 10-45T without chain shortening. It is also compatible with 9-50T cassettes based on v1 experience.

The new eGR v2 is not compatible with old eR9/eGR shifters. Upgrading requires new shifters as well.

Some users successfully use Shimano BH90 olives and inserts with no leaks, while others use the supplied LTWOO parts. The manual warns to use only LTWOO-supplied oil needles and olive ferrules, but real-world experience suggests Shimano parts can work.

Two 14500 button-top lithium batteries (800-1250mAh). Battery life varies but typically 200-300 miles or thousands of shifts. Quality batteries (e.g., Vapcell) are recommended for better performance. The new full wireless version uses a 400mAh internal battery, which may limit range.

Early versions use a magnetic charging port on the rear derailleur. Newer versions require unplugging the battery cable and connecting a USB charging cable. Cleaning contacts is often needed for reliable charging. The new full wireless version has USB-C charging.

Firmware updates are occasionally available via the app, but details are scarce. Recent updates may relate to new aerobar switches, but no major feature changes like left shifter configuration have been reported.

Yes, the new eGR v2 can be used for MTB, though it lacks a proper clutch. Users report the spring tension is high enough for most riding except huge mid-air jumps.

Early versions had water ingress issues in the rear derailleur. Newer versions claim improved waterproofing, but users still recommend sealing connectors with dielectric grease, liquid electrical tape, or heat shrink tubing. The new eGR v2 has good waterproofing, with shifting working flawlessly in muddy/wet conditions and after washing.

Long-term reviews are positive, with users reporting reliable performance over 2 years and 1000+ miles. The 2026 version removed magnetic charging, requiring cable unplugging. No USB-C version is available, and the upcoming eTT wireless groupset has been delayed, possibly due to patent issues.

The new eGR v2 has a fully wireless rear derailleur with an internal battery. Users report it may be replaceable but requires disassembly (undoing screws and clips). The battery appears to be standard, not proprietary, but replacement is not officially documented.

Yes, a flat bar shifter version of the new eGR is now available, along with dual piston brake calipers. It can be found on AliExpress from the LTWOO Factory Store.

A new full wireless 13-speed version has been announced and is now available for pre-order. It features a fully wireless rear derailleur with a 400mAh internal battery, USB-C charging, and new shifters without left shifter buttons. The RD officially supports up to 50T cassettes. Price is around $350-430.
