Did This Chinese Groupset Just Copy Shimano?

Description

The Chinese groupset manufacturer L-TWOO have done something I really didn’t expect… They've ditched their Campagnolo-style thumb shifters, and gone full Shimano!

Big thanks for HoverAir, check out the lineup here: https://dada.link/_tgwa2
They also have a Mother’s Day Sale from May 1-11 with up to 29% off

Today I'll be taking a look at their updated GRT gravel groupset. It’s a 1x12 mechanical groupset, and can support a frankly massive 11-50 cassette, but they’ve taken the design in a COMPLETELY different direction. You now get a swing-lever downshift and paddle upshift setup that looks very familiar, and pretty Shimano-esque. But the real question is, does it actually perform?

In this video I’ll install the groupset, take it out on the road, and see how it stacks up against Shimano, especially when it comes to shifting performance, braking feel, and overall value.

TLDR - The shifting is seriously impressive, but it’s not perfect….

This is the seller I used on AliExpress btw (affiliate link):

What’s covered in this video:
-Full install on an integrated cockpit gravel bike
-First impressions of the new shifter design
-Real-world road test
-Shifting performance vs Shimano-style systems
-Braking performance (and where it falls short)
-Weight + cost breakdown

Bottom line, the shifting is the closest I’ve felt to Shimano from a Chinese groupset—but the braking still needs a bit of work. If they can sort that out, this could be a serious contender in the budget gravel space.

LTWOO GRT Disc 1x12s Gravel Hydraulic Disc Shifter + ZRACE XG Flat Mount Brake Caliper,Carbon Fibre,Benchmark GRX

Created: April 06, 2023

The reviewer tests the LTWOO GRT Disc 1x12s gravel hydraulic shifter with ZRACE XG flat mount brake caliper. He notes the shifter design is heavily inspired by Shimano, with the brake lever used for downshifting and a small paddle behind it for upshifting. The shifting performance is praised as very close to Shimano quality, smooth and predictable. However, the braking has excessive lever travel even after re-bleeding, which the reviewer suspects may be due to mismatched calipers (ZRACE XG) not being the intended L2 calipers. The build quality is good, and the price is around £229 on AliExpress, but the reviewer notes that Shimano GRX 1x12 is only slightly more expensive, making the value proposition less clear.

AI-Summary

Pros

  • Shifting is phenomenal, smooth, light, and predictable, very close to Shimano quality.
  • Build quality is nice, especially the rubber on the hoods.
  • Installation is straightforward with good access to bolts and bleed ports.
  • Compatible with 11-50T cassette, shifting flawless even on largest sprocket.
  • Weight is almost identical to Shimano GRX (1154g vs 1165g).

Cons

  • Brake lever travel is excessive even after re-bleeding, lacking free stroke adjustment.
  • Brake calipers (ZRACE XG) may not be the intended L2 calipers, possibly causing the lever travel issue.
  • Replacing shift cable may be difficult due to cable entry port location under the rubber hood.
  • Price (£229) is not significantly cheaper than Shimano GRX 1x12 ($249 for shifters and calipers).
