A nice and simple solution: wrap your phone (and MP3) player in cling film. Water doesn't get in and it is very cheap! (I don't answer the phone whilst out – only carry it for emergencies.) :-)

I’ve had Hope XC Hubs on a set of wheels for 5 years with Mavic 317 rims and only had to have the rear hub serviced 2 months ago – they’re excellent, long lasting and very durable. Have XTR centrelocks with DT 4.2d rims on tubeless and they’re lovely but quiet. Have had XT hubs on a different wheelset but they didn’t last long – they hated winter riding. Then again – there’s always Chris King……. :-)
