The 25-32 size is really handy because it covers the sizes most commonly used on road and gravel. The 60mm length is perfect for the slightly aero rims I have, no need to mess with extenders and moving valve cores.

The Continental Race Road Tubes do what they're supposed to - hold air. However, I wish that the length of the Presta valves were longer (48mm or so) for better rim clearance.

They just work and work well
Review by Richard Jackman
I run 27x1 1/4" tires on my daily commuter bike, a 1971 Schwinn Super Sport. I have had trouble with tubes failing from the stem tearing at the base, probably due to running 700c tubes on 27" rims. I have been riding with these for several weeks now without incident. I feel confident that these will not fail me some rainy morning when I'm running late to work, mainly because I trust Continental's sterling reputation.

This used to be my go to tube, NOT anymore. The last 3 tubes have all burst at the seams, litterally. All after being ridden for only a few days. Not sure if I got a bad batch but not worth trying these again.

These are good tubes. I have used many over the years and they have never failed me. Flatted on occasion of course but of good quality.
Review by Olmobiker
I put these on and haven't had a single flat....yet !! Seriously they were easy to put on and they have held up very well. They loose very little air.I haven't had to put air in the tubes in months.And most importantly to me like I said, I haven't had one flat since I put them on!!

I like the valve stem and valve and the valve does not seem to bend.
Review by Gary
I've been using these tubes in Continental Gran Prix 4000 All Seasons, 4000S, and now 5000 tires for years. While they're not bombproof (what road tube is?), they provide a good balance of weight and puncture resistance, particularly when coupled with Conti tires. Available in a variety of stem lengths, they're my go-to road tube year round.

no complaints, works as advertised and lasts much longer than the REI brand tubes

Road bike. Excellent quality.

Good tubes, good price.
Review by chrichardsm6
These tubes combined with Conti GP4000 or Gatorskin tires make for a very reliable, flat-free system. Don't lower your tire inflation pressures! Use the recommended maximum on the tire and you won't get flats, especially pinches. There is no low-pressure movement! You also don't have to fill your tires as often. These tubes hold air well enough to go several days - but no further. Check them with a gauge so you catch slow leaks.

Good product, good price. Prompt delivery. Saves a trip to bike shop for a commodity.

Ive been running continental tires for years and love them. Just got a new bike that requires valve stem extensions. To use extensions, the core needs to be removed. These tubes have removable valve cores. Now I need to fall in love with these tubes.
Review by Bill
These are good tubes and the price was good. The stim fit fine and are long enough for inside cone rims
Review by defboost
Can't go wrong with Continental quality. No flats yet. These super light tubes do everything and more.
