TheTremor comes in two shell sizes. Strap adjustments are fairly easy to carry out and the shell strikes a happy medium between round and oval head shapes. A ratcheting closure helps create the perfect fit, though the S/M (54-60cm) tested is a little on the tight side for my confirmed size 59 bonce.
TheTremor is one down from Cratoni's weight saving Ceron model that uses in-moulded carbon strips to maintain the structural integrity of the shell in a crash, and while theTremor uses a simple co-moulded shell it looks plenty strong enough at the front and the styling is right up there with the likes of Met and Giro, with a grand total of 17 vents proving highly effective in warm weather.TheTremor complies with test standard CE EN 1078 and comes with a half-price crash replacement warranty. Also available in size L/XL (58-62cm).
