Continental Race Training Inner Tube

Have always had a good run out of this product.

Ordered the standard Conti Race 28 tubes, 2 with 42mm & 2 with 60mm. For some reason the 42mm were the WIDE (didn't even know such a thing existed) tubes whilst the 60mm ones were the standard Race 28. Seems I could ONLY order the 25-32 (hence the WIDE). Can't be bothered sending them back as they're only tubes but can't use them with my current wheel/tyre combo.

I needed new tubes to put into the new 700x28 Conti Contacts I was mounting to my old road bike. I only had 19-23s on hand so I stuck with the brand that I know. No problems mounting them into the tyres and no problems since. Conti are reliable for their tubes and tyres, so I will stick with them. Excellent price and quick delivery as usual from PBK.

Good rubber, hopefully won't let me down when it heats up ;)

I am a fan of removable valve cores, enabling use of Conti Revoseal to fix punctures without removing tyres/tubes. Conti are almost the only maker of removeable Presta valve tubes. ProBikeKit were the only suppliers of these tubes that I could find in the UK.

Tube worked well in Shimano and Campy Zonda wheels. Paired it with a Continental Grand Prix 4 Season 28mm tire and had no problems fitting. The Campy wheel was a little more difficult to install but the tube handled it perfectly.

These tubes are great for their price. My only advice is to use thread lock on the valves so they do not unthread when you remove your screw-on pump head, and your tyre deflates. This can be annoying if you are out on the road and change a tube after a flat, when you only have one CO2 canister and the valve unthreads after you inflate the tyre.
