Looking at getting another 1-2 spare mounts for my Garmin Edge 800 – for the tourer and the ‘cross bike.
Found this:

But says for 500 – yet looks identical? Will it work? Much cheaper then the Amazon offering – which is £12.34 for a single mount!

My 500 mounts seem fine. A little loose but otherwise the same. However they’re not exactly new mounts so it might just be they’re a bit loose

Wiggle – Option 1 (2 sets included although doesn’t actually say)

I bought some extra bike mount kits from Burrows GPS in Sheffield. They are based in the Toyota Garage near the town centre and I picked up as was passing by but they do mail order.

from memory it cost less than £6

I use one of these. Better position than standard garmin mount.
Mine took just under 2weeks for delivery.

I bought one of those Mooman and snapped it overtightening it..

Thanks guys – have ordered from Wiggle.
