Advanced Safety for Confident Riding
At the core of the Trek Rally WaveCel Helmet lies Trek’s innovative WaveCel technology, a collapsible cellular structure designed to absorb impact forces far better than traditional foam helmets. Think of it as a crumple zone for your head, it flexes, crumples, and glides to help reduce rotational forces during a crash.
Combined with extended rear coverage, this helmet offers confidence-inspiring protection for technical descents and unpredictable trails.
Trail-Ready Comfort and Fit
A helmet that feels right is one you’ll actually want to wear. Thanks to the BOA® Fit System, you can dial in a precise fit with one hand, even mid-ride. The LockDown strap dividers keep everything tangle-free, while the moisture-wicking pads ensure you stay cool and comfortable from the first climb to the final descent.
And if you ever take a spill? Trek’s Crash Replacement Guarantee means you’ll get a free replacement within the first year.
Whether you’re tackling Welsh singletrack or carving through your local forest trails, this helmet delivers premium protection and performance at a fraction of the price.
• Buy now for £55 and ride with more confidence this autumn.
