Effetto Mariposa Shelter Off-Road 1,2 mm vs Muc-Off Frame Protection Kit, Clear Gloss
Which should you buy? Our verdict on both, pulled from our full The Best Bike Frame Protection: 4 Compared (and One to Skip) comparison.
Shelter is the only product here that publishes its construction, and the 1mm viscoelastic layer under a 0.2mm scratch coat is doing something different from a plain film. Muc-Off's kit is the better buy if you want shapes rather than a roll, with 45 self-healing TPU pieces and a size option for e-bike down tubes.
Effetto Mariposa Shelter Off-Road 1,2 mm
Buy itThe only one that publishes its layer construction, and the only one designed to absorb impact rather than resist it.
- A stated 1.2mm total made of a 0.2mm scratch-resistant upper layer over a 1mm gummy viscoelastic layer, which spreads impact energy through the film instead of transmitting it.
- Sold as rolls in 58mm and 80mm widths and 1 metre or 5 metre lengths, so you cover exactly what you want to cover and nothing else.
- Gloss and transparent, stated not to yellow over time, with strong adhesion on curved surfaces, and Effetto claims the viscoelastic layer also damps vibration.
- You cut every piece yourself, which is the slowest way to protect a frame.
- A straight roll does not follow complex shapes like a bottom bracket junction or a fork crown without careful cutting.
- No self-healing claim, so light swirl marks stay.
Muc-Off Frame Protection Kit, Clear Gloss
Buy it45 pre-cut self-healing TPU pieces, in two sizes so an e-bike down tube actually fits.
- 45 pieces in universally designed shapes and sizes covering the high-risk areas, with ultra-strong self-adhesive backing.
- Thermoplastic polyurethane that is stain-resistant, non-yellowing and self-healing, so light scratches and scuffs buff out with warm water.
- Two variants sized by down tube width, 45 to 70mm for downhill, enduro and trail and 85 to 100mm for e-MTB, plus a choice of gloss or matt.
- Muc-Off publishes no film thickness on the product page, which is the single number that decides impact protection.
- Universal shapes still need trimming around cable bosses and welds on most frames.
- No bike-model-specific option, so a complex full-suspension frame will have gaps.
