From LTwoo's 2024-25 catalogue, looks like all the rim brake levers will be refreshed to match the design of the hydraulic levers (with the Campagnolo-style thumb shifter than the older Shimano Sora-style thumb lever in the awkward spot).
Mechanical derailleurs getting a refresh too - different graphics but hard to see what's changed mechanically.
R9 gets the holographic decal treatment
More minimal design continues down through the product line:
A slight graphical refresh on the gravel rear derailleurs but looks mostly the same
Still no sign of an electronic rim brake lever so Wheeltop likely to be the only Chinese player in that space for a little while unless Sensah springs a surprise.
