Continental Race 28 700c x 20-25 Tube.
  • Continental Race inner tube with a choice of 42mm, 60mm and 80mm valve lengths to fit most rim types.
  • 700c x 20-25.
  • Presta valve only.


Hard to find these stateside. So far so good. I use them in my race wheels and I don't like to mess with extenders on the tube stem. Again, being stateside Merlin still made it easy from purchase to shipment. Thanks!
I`ve used these inner tubes, amongst others, and find them at least as good as other inner tubes. They are very reliable.
Perfect, lightweight tubes with the right length valve at a really competitive price.
I have been using these inner tubes for a couple of months now. I am happy with their performance. Even after riding for 40 miles on low tyre pressure, these tubes didn't suffer any impact punctures and have worked well since then,
Tried and tested inner tubes, I always find them a reliable, standard and essential cycling item.
Bought a bunch of these as they are my go-to inner tubes. no issues with them so far!
Have been using this inner tube since day one. One of the best for the price.
Solid set of tubes no problems so far.
My go to choice for tubes. I seldom get punctures & fairly light. great value
My first choice for tubes
No problems with these, been using them exclusively.
Only tubes I use. Reliable and durable,.
Have had no problems using these tubes. Strong and reliable, Maintain good pressure
Always had good luck with these tubes. Best price around.
Very good product, very reliable, reasonable price
Good quality
Good quality tube
Conti tyres - seemed sensible to get conti tubes - no complaints
I always buy continental inner tubes as I feel they are a quality product.
The best tubes on the market with a great value price.
These are my go-to for everyday training. For the most part they've been good tubes. I did have 3 in a row fail where the valve meets the tube. Whether that was a fault in the product or my own wrong-doing (maybe over-tightening the valve nut?) I'm not sure but seemed a little odd that it happened to 3 in-a-row, whereas before would happen very rarely...and I've been cycling for many years now. I just decided not even to bother with the valve nuts anymore.
Price is unbeatable, quality is fantastic.
Keeping as spares as they have been great in the past, delivery time great as usual
Great tubes, highly recommended
Continental Race 28 Inner Tubes are realisticly priced and are a great product which have been proven time & time again
Very long lasting and reliable tube.
Great inner tube for the money, delivered promptly as always by Merlin, my go to online store for bike stuff.
Great Product! can always rely on Conti inner tubes
Excellent tubes at an unbeatable price
Excellent value for money and are reliable and easy to carry in a bag. Perfect for a spare inner tube given its price.
Well made and reliable
I purchased these tubes with 80mm stems. These are the only tubes I buy for my 60mm rims. No need fussing with an extender. Rolled-up they are significantly more compact than a regular tube so they fit easier in your back pocket - and they're lighter too.
Superstition it may be, but along with Kenda, I consider these cheap Continental's my lucky tubes. Seems like everytime I use another brand I get punctures quick.
Great price and great tubes!
Long lasting inner tube.
Not the lightest out there, but super reliable. Make sure you check the valve length when buying
Good, solid tubes. Not the lightest but great value for money. Both my son and wife use these tubes in their bikes as do many of my friends.
Used these for years. Never use anything else for training. Quality guaranteed
Good price for Conti tubes. I've been riding Conti tubes for two seasons and the quality of rubber & weight is pretty good compared to Michelin.
Use this regularly and they do the job at sensible price.
Fantastic tubes, good durability and faultless valves. A great value inner tube
Good inner tube with 80mm valve, ideal for deeper wheels. Very rounded tube and is easy to keep on wheel when fitting
Excellent product. I've always liked these air chambers
Good quality tubed. Fits good inside the tyre and allows maximum air pressure inside the tyre
Continental tubes are always reliable
Continentals are the best. Reasonably priced, especially for the weight.
Good tube, low price.
Continental tyres and tubes are the ones I learned to use over the decade of intensive cycling. Highly recommended!
I like using tubes that have replaceable valve cores, so these are ideal.
Been using these tubes for all of my Pinarello bicycles. They aren`t the lightest but are easy to install and are somewhat resistant to small punctures. The valves are threaded which can be an issue for some people. I wrap a layer of electrical tape around the threads when installing them on my Carbon clinchers to prevent rattling.
These are my go to tubes many miles without failure even on pot holed northern roads
it's a tube, and a good one at that. You need these
I use Continual Race tubes on all my wheels - I particularly like the valves on these tubes
These tubes are reliable and are my go to tubes
Always found these tubes to be reliable, and reasonably light.
The only tubes I ride on.. After thousands of miles; Never had a problem.
Good value for money. Perfect for everyday riding but maybe a bit on the heavy side if you're trying to save grams on your race machine.
Great price for dependable tubes
Good product at a good price. It's tough to find the 80mm tubes for the deeper wheels, so nice to stock up.
These tubes are high quality and the price here are unbeatable
Good Inner tube, decent price, not lightweight but good for commuting.
My standard race tube ;-)
Probably the best value tube, well priced, reasonably light and reasonably puncture resistant
Go to quality tubes. Reliable Conti product.
Haven`t had a flat for long time with these tubes, great and light.
Great tubes, long valve tubes are expensive for me to buy locally (3x the price). Good for my 50mm rims - no need for valve extenders. Fast shipping, no duty delivery to Canada.
These tubes are always reliable I will keep buying them
I have had these before, they are a robust rubber a bit heavier than some others but more durable.
Usual Conti quality, the most reliable long value tube you can buy.
I had been using this tube for a while.. No complaint so far.
Always use these, good quality tubes
Excellent road tubes at a bargain price, I always use these, generally very reliable.
Bought two as spares. Haven't had to use one yet (knock on wood). Well packaged - neatly rolled with an elastic band around, so they will fit straight into your preferred means of carrying when on the bike.
Good value for money. Used them for a few years now and they are just as good as some of the more expensive tubes.
Arrived quickly & a good price. Would buy again.
Still the best tube choice for me - quality rubber, valve and bullet proof valve/rubber interface. I have never had an issue with these tubes.
Tried & trusted
Good resistance to puncture and improved comfort.
Great quality lightweight tubes for my new carbon wheels.
Better than average construction quality.
Great product that suits the deep dish wheels. Good work Conti!
Good product, great quality. I use these all the time. Reliable and equally good for training and in competition
These tubes seem nice and tough...better quality than the last ones purchased. Haven't had to use them yet and hope they are not needed soon but one never knows when you will....always be prepared and carry a spare.
These tubes seem to be of high quality, and installed easily under my 28mm tyres.
It works with a 32mm tire as well
Nice tubes. Ordering more
Basic tube that I give to friends when they expect a puncture repair FOC. Like to keep Race 28 light tubes & Conti Supersonic tubes for my own families bikes!
Easy to use and pump up. First time using this product. Value for $.
A bit thick but quite good for the price.
This friend has been with me since three years ago, punctured almost 30 of them but totaling my mileage of 60, 000 kilometers in total so it is worth every penny.
These are the only tubes I have been using now for the last few years and have had no issues. Match with Conti GP 4000 II and no flats over 3000 miles.
Awesome product awesome price, have been using them on my roadie for years.
Have used in the past and I find they're good quality
Reliable inner tubes. High quality and perfect for all around riders.
The benchmark in bike tubes. You can't go wrong with these ... especially when combined with Continental tyres such as Grand Prix All Seasons.
Very nice inner tube. Bought them because they're highly recommended by all my riding buddies.
Classic. Dependable tubes. Why buy anything else?
Best tubes on the market
Continental makes great products. I hace yet to have a seam or valve fail with their tubes. Sure, you can find cheaper tubes, but definitely not worth the savings if you have to repair unnecessary flats.
Have only had these about a week now but they seem like they'll hold up well!
+ light, great 80mm valve, reliable. - expensive, never use with tube-less tire.
Been looking for long-valve tubes for ages - much less faff than valve extenders and so on, recommended. Plenty of room in 50mm deep wheels.
The go to inner tube! Value/well made...
100 miles in with no punctures and no loss of air, usual Continental quality.
Great product these tubes have lasted me forever in the past I'm sure this one will also.
Strong tube. I nearly pinched it getting it under a new tire and it held up.
One of my favorite brands of tires. Have a locking nut on the valve stem to keep it locked into place which is great for preventing it from breaking away from the tube while inflating.
Tubes are tubes, but I feel better running some conti's... never flat with these.
Having tried cheaper tubes and regretted it, these will be the only tubes I buy from now on. Great quality!
Good quality and good value inner tube.
I have had good success with these.
Tubes are typical continental quality. No problems with them.
Good quality light weight tubes at a great price
Bought 3, 1st was defective but didn't find out until it rubbed flat 10 miles in. There were two 'dimples' in that tube. Other two have 500 miles on them with no issues.
Nice long valves for use with deep rim carbon rims. Non-threaded shaft for a clean look. The tubes themselves seem pretty reliable. Good price from Merlin and fast delivery.
Great tubes at a great price. Removable valves too.
Best tubes available!
Great tube, keeps the pressure!
Usual High Quality Tubes from Conti. I stick to proper brand name inner tubes, with the replaceable valve cores, cheap tubes are a false economy, and to be honest, at the price Merlin sell these for, there's no point in skimping.
I have done around 400 km/week with these, and had no problems. Great service from Melin and fast delivery.
For me the best tubes you can buy. Great price from Merlin.
Not a bad weight for the price, not had any punctures with these yet.
Very reliable tubes that I have been using for several years
High quality tubes
Perfect inner tube, cheap price and fast delivery
Good quality tube. I prefer the non-threaded stem which this tube has
As always with Conti gear they are very high quality - no issues
Conti tubes, basic, do the job, easy to install
Simply superb inners. At Merlin prices grab a bagful.
Very good all-around tube for road bikes at good price
The best tubes you can buy.. Consistent top quality.
These are solid tubes. I judge by how long the valves last, and these tubes don't deflate very much at all.
Good, solid chambre d'air. Alite on the heavy side, but appear to be very durable. (I like super light tubes, but found that I had too many punctures.)
I am a heavy rider (98kg) no problem with this tube and it is a kind of light tube. I bought 5.
Keep air above 100psi for a couple days... I have ridden 2000k without any flat...
Very good inner tube. Fits both 23c and 25c. Excellent service from Merlin Cycles as usual.
Just as advertised. A great, inexpensive training tube.
Does the job! Reliable and better than cheaper brands
I have been using these tubes for some time, very reliable. Price is excellent.
Usual reliable Conti tubes. Only brand of tubes I use nowadays
To be honest I am not sure how to rate an inner tube. I have never had much trouble with any inner tube except for the occasional flat which you will get from any inner tube. I went with Continental this time for name recognition and I have no complaints.
Great tubes. Hold pressure well and used with Continental GatorSkin road tyres I haven't had a puncture in almost 2000km...
Good value tubes. I've been using them for years.
Amazing material,great feeling on the road, I recommend these tubes.
Seem to hold air a bit longer than non-branded tubes.
These tubes look solid. I only have about 60 miles on them. All good so far.
After riding on Michelin tires and tubes for the past fifteen years, I thought I would try Continental tires, so I added the Continental tubes as well. I am impressed with the quality on both tubes and tires; it is much better than what I have been experiencing with Michelin.
Good quality inner tube - does the job
Continue to be the best. I've tried many other brands and these last the longest plus, I've never experienced any manufacturing defects. This unlike some Michelin Airstops where three out of six failed for no apparent reason!
Usual conti quality. Better valves than other brands.
I thought all tubes were equal but these do look a little better quality than most
Great reliable tubes!
Conti are a brand you can trust, wouldn't buy anything else.
Good reliable tube, as you would expect from Continental. You want to ride with confidence and these give you that.
I've been using this tube for more than 1500km and got no punctures so far, even with a cheap tyre. I guess it can't get better than this.
Have used these for past year since getting my new roadd bike. Not too many punctures except when running on worn tyres tyres last couple of weeks before I purchased new ones from Merlin. Had a couple of issues with slow punctures due to valves but may have been me using the track pump. Ovearll good buy and happy with them.
Fitted with a pair of continental GP Force/Attack tyres, first choice after using Continental tubes on my Mtb, perfect quality.
Pressured right up! Hasn't leaked over the last three days since installation.
Fantastic tubes. Great durability. Percentage of punctures has decreased dramatically. Very fast delivery!
Good quality tubes.
First time ordering this inner tube, so far so good
These are very good, recommended!
Great inner tube, holds pressure and good long valve choice.
A good quality, reliable tube
Great tubes good quality
Good ol' Continental. What more can I say. Quality tubes you can rely on not to fail when first inflated.
Fast delivery and good value.
Great lite tube
Good tubes, very rubbery! Longer valve-stems for those 'dishy rims' Well priced.
Quick service and delivery
Easy to fit, removed a few times using with indoor trainer trye , holds pressure , and no bumps on trye seam to be good , also carry as spare , will buy more
Unboxing this tube I can see the high quality of the product, A+++
Good value for money.

Good value std tubes highly recommended
Tubes ok
nice tubes.
Best price on the net . A must have
