We found these to be a good price but were hesitant because there were no reviews. I rely heavily on customer reviews to help me decide if it’s worth the purchase or not. My husband said these are all the same thing regardless of reviews as long as it’s the right size. So we ordered them. One tube was ripped upon arrival and the stem sizes weren’t accurate. Shipping was fast but I returned the product due to sizing and one tube being ripped. I gave 2 stars because the item did arrive quickly and the product was correct except for stem sizing. The stem was smaller than advertised as we measured it and even compared it to the tube that needed to be replaced.UPDATE:The company reached out to me and actually sent me out the product again. This time the product was correct so I changed my review from 2 to 5 because customer service was AWESOME! They went above and beyond to make sure we were satisfied. We decided to give their company and product another try and now we are happy we did. Product itself is great quality and it ships quickly (all sizing is correct). Super happy with the company and the product. They truly care about the customer experience! ### ⭐ All defective *by A***P on Reviewed in the United States on April 14, 2019* I've been replacing my bike tires for years, and I've fortunately learned to always pump the tires to at least 20PSI before installing for this very reason. I took a try on switching from Qtires to Projekt but will be switching right back after this experience.Open box + Inspection: Poorly folded tires with ashy, very old looking tires. These tires looked significantly older than the 2yo tire that got a flat that I'm trying to replace (last picture, old tire on right, 4 Projekt tires on left).Tire 1: Pump to 10PSI and see a pinholeTire 2: See a bubble defect, pump to 25PSI and tire blowsTire 3: Presta valve defective even after checking pump on multiple bikes and multiple pumps, tire won't let air in or out, valve looks poorly made and must not be sealed.Tire 4: Presta valve defective even after checking pump on multiple bikes and multiple pumps, tire won't let air in or out, valve looks poorly made and must not be sealed.This is absolutely unacceptable and ridiculous. Never in my years of fixing bikes have I ever had this before. 2 hours of my Sunday wasted. ### ⭐⭐⭐⭐⭐ Worked well for a first round go at 33 miles *by O***Y on Reviewed in the United States on September 10, 2018* So I got the 2-pack 700x28-32c tubes and combined them with the Schwalbe Marathon HS Wire Bead Tires listed below.https://www.amazon.com/gp/product/B004JKIUD6/ref=oh_aui_detailpage_o01_s01?ie=UTF8&psc=1My original tubes were Kenda along with my tires and one poppe, so I decided to redo them both. I got the tubes pumped up to 80psi with those Schwalbe Marathon tires and rode my bike from Capitol Hill in Denver 33 miles to Boulder. I lost about 25psi of air after 15-18 miles. This is no fault of the tube as the altitude is over a mile high and breaking in the tires and tubes needed to be done. On around 18-19 miles, I found a bike pump station and then pumped them up to 100psi and was then rolling quickly and efficiently. . They worked really well. So good review on a newly listed product. Hoping this review is helpful for others. Everyone needs bike tubes so go ahead and buy some bike tubes.Ol' John Boy --- ## 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.hr/products/72057110-projekt-presta-valve-bicycle-inner-tube-700c-iso-622-27](https://www.desertcart.hr/products/72057110-projekt-presta-valve-bicycle-inner-tube-700c-iso-622-27) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-04-22*
