Nonetheless, it worked out great, however I had a very hard time betting the other beat up tires that were on my wheels, eventually I got them off and installed these tubes along with my new tires, it all looks great.

Good Deal! ### ⭐⭐⭐⭐⭐ low Quality Control at Amazon Warehouse *by M***D on May 30, 2020* My rating of this product reflects my opinion of these tubes when purchased in new condition. Although the rating is positive, this review is meant as a warning to others that you might, or might not, get a great deal buying from Amazon Warehouse. So far, I've bought 4 of these tubes from Amazon Warehouse. The price is GREAT. I paid around two dollars each. I bought two each of "Condition: Used - Like New" and "Condition: Used - Very Good". The latter were described in detail as, "Minor cosmetic imperfections on the corner of the item. Item will come in original packaging. Packaging will be damaged." The "Condition: Used - Like New" were both exactly that: They looked and performed like new. No, I don't pinch my tubes when installing them. But somebody shopping on (and returning to) Amazon does. The two "Condition: Used - Very Good" tubes were both popped in the same place, where the N00Bs so often pop their tubes. Obviously, Amazon Warehouse doesn't attempt to inflate returned tubes. And the visual inspection skills at Amazon Warehouse aren't perfect. One of the holes made when N00B pinched his (Yes, I am certain. Any lady would have followed instructions.) tube was so large it created a flap of butyl. ## Frequently Bought Together - Continental 42mm Presta Valve Tube - Continental Ultra Gatorskin 650x23c --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.il/products/2173584-42mm-presta-valve-tube](https://www.desertcart.co.il/products/2173584-42mm-presta-valve-tube) --- *Product available on Desertcart Israel* *Store origin: IL* *Last updated: 2026-07-06*
