Latex loses enough pressure overnight (or even over a very long ride) to require topping up, punctures easily, and can’t be patched.
Not really, they lose about 8-10 PSI/night, which means I pump up to about 110 PSI and commute for three days on 25c. Latex tubes are the easiest to patch, just use proper Rema TipTop patches and vulcanising glue and hey presto, the patches will stick like nothing else.
Where they suffer is in installation. They are so flexible that if the tyre bead does not seat perfectly, the tube will squeeze underneath and go bang once ridden – and the ensuing 10 cm slash means another £8 wasted! (well £16 in my case as I’ve done it twice). In fact I once had a screw hole in a brand new Schwalbe One and the replacement latex tube squeezed through the hole and exploded (how I learned to patch them!).
So if you don’t mind pumping them up every three days, are careful with installation, and don’t mind the extra rolling noise, they are light and have a sublime tubular-like ride.
I buy Michelin air comp from Decathlon.
