How much is too much? The amount that leaves you feeling constantly tired and jaded.

Views from my bike ride earlier this week, which incidentally was my longest ever day ride, 70 miles, including 6,000 feet of ascent.

This thread gives more insight into thinking of forum members than it does motorists

Is it not all about recovery? A big climb is normally followed by a big descent, and a chance to recover. Constantly undulating terrain up and down with steep gradients provides fewer opportunities to recover.

And also how tough any ride is highly dependent on the effort put in. Twenty miles on the flat cycled at your maximum effort could conceivably prove tougher than a measured steady effort up a big climb.

Hi Jonathon, the first attempt involved a screw on CO2 inflator. I wondered whether the high pressure had caused the problem so the second and third attempt used a lezyne screw on mini pump. Obviously pressure achieved was lower but tyre seemed sufficiently inflated for limping home. The lezyne pump was a screw on type too, and I think that might be a contributing factor. However having said that, I’ve never experienced this problem before using the same equipment.

Hi Colin thanks for reply

Yes, obviously ensuring core is properly tightened is the thing to do. Thing is I tried three ‘out of the box’ tubes. Two of which I was carrying and a friends. The same thing happened on all three. Eventually we got it sorted, but as you can imagine it caused a bit of angst, not to mention time, Obviously doing this on the side of the road 20 miles from home is more stressful than doing the same thing at home.

I just wondered whether carrying a tube with a non-removable core might be a sensible thing to do on a ride. Those tubes tend to be cheaper whether that is reflected in overall quality I wouldn’t know. When home it would always be possible to switch the tube, or even repair the punctured tube, refit it and put the non-removable core valve back in the saddlebag ready for next ride.

Just looking for a bit of advice from more experienced cyclists.

Hi, on a ride today I had a problem with presta valves when repairing a puncture. Basically after fitting a new tube and inflating, the core came out with the pump. This happened a couple of times. It’s the first time I’ve experienced this problem. Any tips for avoiding?

For example a tube with a non-removable core. Michelin do one called the Airstop. They seem to be in two possible sizes for my tyres 18-25 and 25-32. If I go down this route would I be best with the narrower or wider tube for 25mm tyres? In reviews my tyres which are Conties have been measured at 25.6mm.
