So, I'm getting myself all set up for a two week trip to Portugal in mid-September. Luggage is sorted (kriega tailpacks, SW Motech tankbag), clothing is sorted, bike is fit to go. All I need to sort is navigation, for which I'm planning to use my phone, with a battery pack to keep it juiced up (don't have a plug on my bike). However, trying to find a simple solution that covers every base isn't easy - I need a waterproof phone case (that I can use for other things like my windsurfing etc), I need a mounting system on the case (slim enough to fit in a pocket still), and a mounting system for the bike. I came up with an elegant solution: 1. Lifeproof case to keep my phone cosy and dry 2. Quadlock mount to glue to the back of above case, & Quadlock 1" ball joint 3. Ultimate Addons fork stem mount, with a 3" extender to fit 1" mount ball. (without the end adapter) Great! But wait.... now that all of the above is ordered (except the Quadlock mount), I realise that the 3M adhesive tape provided with the Quadlock mount won't stick to the Lifeproof case, because its Polypropylene (a Low Surface Energy plastic), and LSE plastics are way more complicated to adhere to.... It looks like I might have to buy a LSE specific adhesive tape AND a primer to be able to use it. For another £30 or so. And naturally it only comes in units far larger than I need! Rant over. Anyone got any ideas?
