Standard Presta Valve Inner Tube Road - 700c
Road standard presta valve inner tube 700 x 19-25c, 40, 52 or 80mm valve length.
StevenGood inner tube, fits well. One thing I noticed is that they hold the tyre pressure well. I've had other inner tubes that seem to lose a fair bit of pressure in a single day.
Sir LoureiroCheap, but with a very good quality
Biker1125I received the tubes today. I have not used any yet but having had 7 punctures in the last two weeks I am sure I will. These tubes are much thicker than the ones I currently use. This is good for me as maybe they will be a bit more puncture resistant. I am ordering more! FYI: It took 14 days from the time I ordered these to receive them In Mobile, Alabama.
Mr. PMJpolicajtA little heavier(135g for 60mm valve tube), but looks very sturdy. Will be used on winter bike, so weight is not an big issue for me.
Mr WitteborgBest price on tubes I've ever found and super durable
Dr MorganGood so far, have only used one and installed on wheel 500 miles ago.
Mrs HAJINLIANAs inner tubes go, they are so good, always have extra in the house,
CUontheroad, AdamsNice tubes and an even better price for the hard to find 80mm stems. Thanks, MCL. I will be back soon. CUontheroad...
SmurphyGreat tubes for the price, no issues as of yet
MaI have not use from this purchase but I have bought and use them before and work great for commuting .
Weak_in_the_KneesThey hold air well!
Mark SGood value inner tubes, being used on my commuting bike and no problems at all. Maybe not the lightest but that doesn't matter on a commuter bike. Recommended!
AronA basic standard inner tube with presta valve. You cannot go wrong with these if you choose the proper length of valve.
Mr SmithWhat can you say? Reasonably cheap and beyond checking the pressures once a week have not caused me any problems.
Paul S.Great price on durable tubes. I will not be using them unfortunately due to the thickness and weight of these mothers! I have to roll them and fold the last portion just to fit them into my bottle storage and I tight roll them so theres no air in them at all!, bummer cause I bought 10 of them in two different size stem lengths (60mm and 80mm). I usually use standard Kenda tubes, those are super lights compared to these mammoths and take up about 55% of space that these do. Wish someone really put out how much bigger and heavier these are then your standard tube, I don't have my scale on me but they feel twice as heavy no joke! I guess I'll use them for friends who have blow outs on the road when they don't have any left, thats all I can use them for. As always Merlin rocks!
heasleyGood service in the delivery, only used one so far, seems quite heavy, but perhaps more resilient.
HallGood basic inner tube, at a cheap price.
Mr MoodyPurchased as a back up, so luckily have not needed to use them as yet. However, after 30 years using tubes, I have no doubts about their suitability.
ZvonimirLight, good tubes - no complaints.
Mr shanGood puncture resistance. No air leak
McCrearyDecent Tubes for the price. I haven't flatted yet!
Fish on a bicycleIt's round and rubber. No leaks yet. What more can you ask! Great service from Merlin as usual.
JonnyLooks like these are as good as more expensive tubes. On first couple of weeks no problems.
SimonBrought these in bulk. I have found them to be better than expected not losing as much air as other I have used. A great price.
BROOKSGreat value for money product, Appear to be as good as tubes twice the price.
Terry HanniganCheap, seem to work as well as the contis
Mr Brownits a generic tube that appears to be of decent quality at a good price. Holds air - what more can you expect...
Mr BlackmanHolds air well and looks high quality.
Mr RoeIt's a tube, the quality is good, what more could I need.
TalawanGood quality tubes...
Cameron ScottThese are generic, 100% butyl rubber tubes. They appear to be equivalent to a Specialized thin tube. They are far from heavy, but will likely not provide much puncture resistance in the event that material is able to get through your tire. If you are looking to shave a little weight and you need a tube that is on the skinny side, look no further.
Mr RowntreeGreat inner tubes with decent valve length
Mr morganGreat price, quick delivery, not exciting but vital !
ThomasNice rubbery feel to them. They inflated fine.
Mr AdamsThis is a good solid inner tube. Performs as expected, with a very good price. A great value.
Mr SaxbyThese are a nice quality tube and seem to be more "rubbery" than a lot of inner tubes that are on the market. They also seem to hold their pressure better and for longer. 500 miles so far with no problems.
FrankTubes arrived very timely. Tubes look same as tubes purchased at LBS for a lot more. So far I have 200 miles on 1 tube with no issues. Would purchase again.
Mr OtisGood inner tubes. Seems to hold pressure longer than the other tubes I have had.
Mr PrattGood tube, no punctures yet.
Mr De WeverGood product, only a little more weighty when compared to the branded product
Mr RussellThese are your standard presta butyl rubber tubes. What I like is that the stem and valve are colored black. They are CSTs which are good quality. Would definitely buy again.
Mr GillenDecent economy tubes.
Mr MitchellDoes what it's supposed to do at a decent price. Feels a bit heavy, but that's not gonna bother me this winter.
Mr MayGood tubes, I use these rather than fixing punctures !
EddyGood price, quality looks fine. Not the lightest but also does not look too fragile. No issues so far.
Mr YILDIRIMGot the same tube on another bike, it's been over 2000 miles, no problems so far.
Mr RichardsWe were really impressed with the quality of this tube, it is a thicker rubber than I have used in the past when I have bought one from the Gold Coast, the price was amazing as well, we will definitely keep purchasing from this supplier in the future.
Mr SivillGreat innertubes easy to fit very robust, don't need to be too gentle in case you pinch them unlike other tubes I've had ,plus very good service and prompt delivery :-)
Mr SmithNever had any issues with these tubes
Mr VazzolerI've been using this tube in the front wheel for more than 2000km, got just one puncture but it was a piece of sharp and thin metal which would pierce anything. I repaired it and it was ok again....so far.
