Review: They Truely do work!!!!!! - The latex tubes are breathable, extremely powerful rolling resistance, and the wheel caps are VERY useful for all the pumping up of the tires( daily) that will need to be done. I believe SILCA is the best company for the caps as well as the wonderful Latex Tubes!!!!!
Review: can a latex tube ever be considered on a value basis? - Lets face it Latex tubes are a qualitative purchase - Butyl tubes are value propositions This is a really nice riding tube - I had some l schwalbe ultremo tires left over from a box I split with a friend. Love the tires with light weight butyl tubes - Amazed by the tires with the Latex - these tubes are great - Are they $4 a tube better than the vittorias? I would say no. but they are non-the-less really nice. I love the smooth stems - but my time on a tubed tire is limited as I am building a tubeless wheel set . I will run the last set of Ultremos and Silca latex tubes until the miles take there toll (riding about 120miles a week with the wild fire smoke reducing my outside time right now) then off to find a tubeless tire i like. I will keep the latex tubes on hand for emergencies with the new setup when done.

**Q: Have easton ea50 aero wheels... is the red lining they have in them enough or do I need to add wheel tape? Thanks!**
A: That seems like it’s the stock rim tape. Lucky for you if the rims are tubeless. I have heard the Silcas work fine with stock tape for clincher wheels. I have posted a related question.

**Q: How can I make sure I’ll get the extender and speedshield ?**
A: I've bought quite a few & they've all come with extenders & shield thingies.

**Q: Work in Shimano duraace c50?**
A: Probably not as the C50 rim depth is 50mm and the valve stem is only 42mm.  The only way to the finish line is adding a valve extender.  Even if you used a Vittoria Latex tube, a valve extender would be necessary.

### ⭐⭐⭐⭐⭐ Silca tubes are the best
*by K***S on April 1, 2021*

These are manufactured by Vitoria on Silca’s spec I’ve always liked Vitoria latex tubes but they have been fussy to install and prone to pinch flats during that process The Silca tubes seem to have corrected that issue with their version on Vitoria latex tubes They both installed without a problem in new tires (which are even stiffer than tires with some miles on them)- no pinch flatting- I got the extender kits and again, Silca nailed it. They went on nicely to the original valve- even came with a little tool for installation- and the little aero rubbers that come with the extension valves were easy to install as well although i question their use Either way the Silca tubes are the best I’ve used
