⚡ At a Glance
- • Sweat Absorption: Dual-layer mesh and waterproof diving cloth catch hold most sweat across the top tube
- • Best for: Indoor cyclists using trainers who want to protect the frame and bottom bracket
- • Not ideal for: Long-term outdoor weatherproofing or full-frame storage protection
A wide, triangular front and narrow rear combine wear-absorbing mesh with a waterproof backing to trap sweat. Elastic fittings and hook straps secure the guard to most road and mountain bike frames.
Protects frame from corrosion - with dual-layer sweat-absorbing fabric
The outer layer is wear-absorbing mesh while the inner layer uses waterproof diving cloth to catch and hold sweat, preventing salts from reaching paint and metal. The dual-layer arrangement increases holding capacity compared with single-layer belts.
Reduced risk of frame and bottom bracket corrosion during heavy indoor training, extending the usable life of the bike and reducing maintenance needs.
Secure fit for most bikes - with elastic band and adjustable buckles
A wide elastic band with a large adjustment range pairs with adjustable buckles to accommodate common tube shapes and sizes. Two sticky hook straps at the front and an elastic loop around the seat provide quick anchoring points.
Stable positioning prevents slippage during stand-ups and intense intervals, so the guard stays in place without interfering with pedalling or knee movement.
Easy to clean and reuse - with hand-washable materials
High-quality cloth components tolerate repeated cleaning; recommended care is hand washing in warm water below 40°C to preserve the waterproof backing. Durable stitching and materials resist wear from regular use.
Quick maintenance between sessions keeps the guard hygienic and ready for repeated training, offering a long-term protective solution rather than a single-use cover.
