Description:

Upgrade your Brompton G Line with the H&H G-Line Stem Catch Mount — the compact folding solution that enhances both function and aesthetics.

This mount secures your head tube in the folded position, preventing it from sticking out and interfering with storage or portability. Unlike the original plastic stopper that easily deforms over time, this premium upgrade features a CNC-machined aluminum body, titanium bolt, and dual spacer design, allowing fine-tuned positioning for a snug, stable fold.

Engineered for precision and built to last, it reduces the overall folded width by approximately 20mm, giving your Brompton a sleeker, tidier profile whether stored at home or on the go.

✅ Sleek CNC-finished aluminum body – durable and lightweight
