Continental Race – Air Chamber (28 inches)

Started using these as they were a recognised brand and were well priced if purchased in bulk (you can get them for less than 3 quid a tube if you shop around). Never had any quality issues whatsoever and certainly never had any 'fail for various reasons within an hour of mounting' (?!?!?). Only thing to note is that the valve core is often quite loose and requires tightening up before you throw one in your saddle bag and head off out. My pump (Topeak Race Rocket HP) screws onto the valve core and I've had the whole core unscrew after pumping up my tyre and when unscrewing the pump from the valve stem.

It popped when my road bike was only at 60psi , when its recommended is 80-110. Not sure if the tyre or the tube was the problem
