Review on 🚴 Sunlite Bike Tube, 700x18-23 (27x1) with 32mm PRESTA Valve by Mark Patterson

I bought 4 tubes from Niagara Cycle Works and 2 of them were defective. 1 had a flat tire right out of the box. I aired it on the outside of the tire to make sure it would hold air before installing it and it wouldn't hold air. Another was fitted and on the second attempt to fill it the presta valve broke. A very disappointing experience. Don't buy these tubes. The only reason I give it 2 stars is because the other 2 tubes worked fine. There is one good thing though. If you buy from Niagra they are very friendly and helpful and have replaced two tubes with another brand. Will definitely buy from them again!
