- Reviewed in the United States on October 25, 2024Size: 700 x 35 - 40 (27 x 1.375") / 32mm ValveColor: BLACKVerified PurchaseSo far, so good. Purchased a Bell brand (https://www.amazon.com/dp/B007SNUJEY?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1) and it was too big for my tire although it says anywhere from 35 to 43 mm it did not fit my tire. This one was a direct fit perfectly, i do highly recommend when you do the replacement to use a plastic bar tool, once you have it inflated a little bit and you put it in the tire, then you put that back on the rim, you got to pry it back out a little bit to get it to set back in the tire all the way, then continue putting the tire all the way on the rim. Then confirm before airing it up to what it's supposed to be that the tube is set back into the tire and it is all the way on the rim, then air it up to whatever it's rated for. For whatever reason it was a pain in the ass to find out exactly what tube I needed for the tire although I had the sizes, measurements reading through this product also had the best explanation on that. Also a big plus that the valve stem was American and not Presto or whatever cuz then I had to buy it after valves to go from Presto to american so I could air it up. I don't know, overall good product.
- Reviewed in the United States on December 16, 2013Size: 700 x 28 - 35 (27 x 1.125 - 1.25) / 48mmColor: Threaded ValveVerified PurchaseI have ridden thousands of miles on Sunlite brand tubes. The ones I'm reviewing today are lightweight. One of these did recently fail on me, however there was a hole in my tire that corresponded to the hole in the tube (it is very clear to me that the failure was due to debris and not the tube's fault).
Match the tube you buy with the riding you do. The tubes I'm reviewing here are light, I ride them on roads and paved bike paths where there is not much debris, in these conditions I rarely experience flats.
If you experience flat tires a lot, Sunlite does make other tubes that may fit your need. For Example, when I lived in Nebraska where flats due to thorns were common I ran Sunlite thorn resistant tubes (these cost about twice as much, and are quite a bit heavier). On many occasions I stopped and waited for my friends to fix flats caused by thorns without ever having a flat myself. In fact, after around 2000 miles of riding Sunlite Thorn Resistant tubes in an area known for thorns I experienced two flats, (1) a 16D nail that my tire picked up on the edge of a rural road, and (2) a broken spoke that was pushed down through the inside of the tube. Please note, my mention of thorn resistant tubes is for illustrative purposes. The product I'm reviewing is not thorn resistant.
I've yet to have any brand lightweight tube last more than about 500 miles in the rear when riding 'unprotected' (light tire, light tube, no insert). Flats are a fact of life for the 'more than casual' rider. The tubes I'm reviewing do fall to the higher end of that 500 miles. If these tubes can run 500 miles with me riding on them (I'm a big/'Clydesdale' rider), then I don't think quality is an issue at Sunlite.
Finally, if your tire goes flat within 24 hours of replacing the tube, you probably did something wrong. Here are some tips, learned through my experience, and the experience of those I've ridden with, that might help.
1) If your rim requires one, make sure that the protective strip (usually this is a big rubber band with a hole in it where the stem goes through) is in place before you put the tube/tire back on.
2) Prior to repairing a flat, run your fingers around the inside of your tire, whatever popped your last tube may still be in there (or still embedded in the tire wall/tread). Note, whatever popped your tube is probably at-least a little sharp, use appropriate caution when feeling out the inside of your tire.
3) When the situation allows, a little powder inside the tire, or rubbed onto the tube, can help avoid pinch-flats. I also like to inflate the tire to about 20 PSI and then bounce it around some to help the tube settle into place before heading for full pressure.
4) Don't over-tighten the nut that holds the stem in place, and make sure the stem is not sticking out at an angle before you fully inflate the tire.
5) If you're on the trail, be careful with your trail pump, pushing back and fourth on the stem while you pump can damage the tube, or even your rim.
- Reviewed in the United States on August 26, 2020Size: 27 x 1-1/4" / 32mm ValveColor: BlackVerified PurchaseHaving the exact size of "inner tube" for one's bike exists as a very important issue for myself.
Given my recent tubes' (3; older; just a tad undersized, yet "they should fit, also 'definitely fit' ") very loud, nighttime (I was sleeping in all of these experienced occasions) "bang," followed by a distinct "hiss" (as the remaining air escaped the tubes abruptly awakened me); I'm convinced the "VERY BEST" way to choose one's "inner tube(s)" should involve one choosing "the exact size" inner tube for one's bike, rather than an approximate size based on "available" inner tubes of "nearly the same dimension." These "approximate size" inner tubes definitely "fit," yet aren't the BEST IDEA for one's bike. In my case the "older" (previously used) inner tubes' stems' "failed" with a "BIG BANG." The first time was the most traumatic, as I thought a "gun" had just been fired inside the building where I rent a room. EGADS! The "brand new" tube (have yet to receive the second one, as I only figured one would blow, not two! I was wrong) exists as much more flexible, pliable as well as incredibly easy to fit onto the rim/tire, simply by following the instructions inside the box! (I happened to buy "sunlite"). I doubt I'll ever buy only one tube at a time in the future! "When one blows, another's soon to follow," seems to be the best adage when buying inner tubes. It's quite similar to when buying "new tires" for one's vehicle. Always buy at least two "new" tires, placing them on the same axle of your "4 wheeled" (not 4 Wheel Drive) vehicle/automobile, not different axles. TY!
