So my new tyre warmers rocked up a couple days ago and I thought to myself, heck, I'd better check they function before getting all the way to Victoria and finding that they don't work. So I mounted them up to the tyres this morning just for the lulz before my ride with my mate. On they came. These are non digital warmers but it's all I'll need. Two led indicators, one for heating (orange) one fore ready (green). It was 2 degrees when I went out to the shed to put them on. They took a grand total of 30 mind to complete their heat cycle. Well impressed. These warmers are emtek brand. You can find them on eBay or direct from the guy. $220 with free delivery, can't really go wrong. Postage was quick and efficient.
