Same as previous deal but ~$50 AUD cheaper. Use a CC with fee-free FX for the best deal. Cheapest on .co.uk even with cashback on .com.au.

For anyone who doesnt understand what this is it is a crankarm for a road racing bicycle that contains a strain gauge and can keep track of how much power you are generating through your legs (well, as it is only for the left crank, 1 leg). This suits a 105 5800 groupset
Crank lengths available: 165mm, 170mm & 172.5mm (Extra £4.57 GBP / ~$8.30 AUD)
PBK also have the 4iiii Ultegra 6800 left arm crank power meter at £254.07 GBP / ~$461 AUD with code delivered, but only in 165mm.

If anyone is after a local alternative, Pushys are still selling Stages 105 5800 left arm crank power meters for $400 delivered.
I would caution anyone from using ProBikeKit after an absolutely shocking experience i had with them recently. Beyond terrible and would never shop there again. They seem particularly bad when offering "super deals" etc. etc.
