Innertube Issues?
Both a friend and I recently purchased Cube bikes, which are fitted with the same tyres and tubes. We are both on the heavy side. Our tyres are 700 x 23 on road bikes.
I pump my tyres to 120 PSI for every ride, but even after a short trip (12 miles is the shortest I have done), the tyres have gone down by about 20 PSI front and back. My friend has exacly the same problem.
A third friend who bought a Cube at the same time (C2W) is much lighter and isn't suffering from this issue at all.
Is it possible that the innertubes are just poor and can't handle the extra pressure of the weight as well and leak until they find an equlibrium (ie. 100 PSI in this case), or is this a common thing for heavy guys on road tyres?
