Rhinowalk Waterproof Bicycle Triangle Frame Bag – 4L TPU-Coated Under Top Tube Storage – For Road, Mountain & Gravel Bikes

Description

Maximise your bike’s most underused space with the Rhinowalk 4L Triangle Frame Bag. Designed to fit snugly within the frame triangle under the top tube, this bag delivers serious storage capacity without compromising your riding posture. The narrow 6.5cm width is engineered specifically to prevent thigh contact during pedalling — a detail that makes or breaks long rides. Built from TPU-coated waterproof fabric with a weather-sealed side zipper, your essentials stay dry even during unexpected Dubai winter rain or after a hose-down cleaning. The 4L capacity holds a hydration bladder, multi-tool, snacks, spare tube, phone, and wallet — everything you need for an all-day ride to Hatta, Showka, or Al Qudra without bulky bags. The five-strap fixation system ensures absolute stability over rough terrain and high speeds. Reflective Rhinowalk branding adds nighttime visibility. Compatible with most road bikes, mountain bikes, and gravel bikes — measure your triangle (39.5 × 23 × 6.5 cm) before ordering to confirm fit.

Instructions:

1. Position the bag inside the frame triangle, under the top tube.
2. Wrap the two top straps around the top tube and tighten with the velcro closures.
3. Secure the seat tube strap around the seat post for lateral stability.
4. Use the down tube strap for the third anchor point.
5. The five-band system ensures rock-solid fixation — adjust as needed for your frame size.

Precaution:

Measure your bike’s triangle area (L: 39.5 cm x W: 6.5 cm) before purchase to confirm fit. Not suitable for compact or small-triangle frames.
