M E T Trenta 3K Carbon Mips Helmet Black/White/Red - M 56-58
- EAN 8015190301617
- Brand: MET Helmets
- Product Model: 935529
This Trenta 3K helmet from MET is a special UCI World Champion II edition for road riders who care about speed, ventilation, and a secure race fit. The 3K Carbon construction helps keep the helmet light at 245 g, while the MIPS Air system adds rotational impact protection without turning the inside of the helmet into a heavy liner. Developed in MET’s wind tunnel, the compact shape is made for fast road use, and the 19 ventilation channels help keep airflow moving during climbs, hard training blocks, and warm race days. The 360° head belt retention system, Air Lite straps, and sunglasses storage ports make it practical for long rides where small comfort details start to matter.

Measure the circumference of your head (just above the eyebrows) to determine your helmet size.
If you’re between sizes, choose a MET cycling helmet in the larger size to make sure your helmet fits.
Most MET bicycle helmets and MET children’s bicycle helmets are equipped with a turning mechanism, so you can tighten the helmet to fit you.
This also applies to MET children’s bicycle helmets.

The bicycle helmet should be placed on top of the head, so not too far back or over the forehead.
Adjust the helmet’s inner mechanism and chin straps while you’re wearing the helmet (the straps should come together in a Y-shape just below your ear).


A proper bicycle helmet should have a lifespan of 3 to 5 years.
If your bicycle helmet is getting too small or if you’ve had it for a few years, it’s wise to replace the helmet.
Always replace your bicycle helmet after a crash or other type of impact, as the shock it absorbs during impact will permanently damage the helmet.
