Debate the safety aspect of listening to tunes on the hill if you must, but if you’ve decided what you want, you’ll know that cables are a drag, and I’ve yet to find cables that are tough enough to hack a full season on the hill. Giro make some of the best helmets on the market, and the Bluetooth link in fits with most of them. You can listen to tunes from your mobile’s MP3 player and if you enable auto answer it will switch automatically to an incoming call without even touching a button, so you can go straight from Milli Vanilli to Moshi Moshi. Sweet. Available from Toyu. Call 0136-21-4055. ¥5,250 (Bluetooth attachment), ¥19,845 (G10 helmet).
