Continental MTB Cycling Tubes, 29 x 1.75-2.50, Presta Valve 42mm, Mountain Bicycle Tubes & Value Added Tire Levers. (Tubes and 2 Tire Levers) - Bulk, No Retail Packaging

Was worried with all the other reviews but these worked out perfect. Will be buying more packs as needed in the future.

Continental products have always been rock solid. I haven't had the need to use one yet but have no doubt of their capability.

Seller please make sure you are sending the correct sizes . I ordered 29x2.50 because that's the required for my bike. You sent me 29x 1.75. Although they do work but because of my larger tire size the tubes have to stretch out more when inflated making the tube wall thinner and weaker than the correct size

used these in some MTB 29” tireswas too lazy to fix the tubego me back on the roadordered some extra 😂

These tubes are identical to the individually boxed Continental tubes that I've been using. The only difference is that all four tubes are packaged together in a single plastic bag, instead. They are good quality and lightweight tubes at an affordable price.

I always carry a back up bike tube. Who wants to patch a flat when it is over 100 outside. Not me. Pack a spare tube makes it easier.

This is supposed to be a 29x2.50 tube, but compared to another 29x2.40 (see picture) it is very small. It will work, but when undersized tubes are stretched to fit a too large tire, they puncture that much more easily. Not happy.

I bought this product and never used it, when I needed to use it it came out defective and I was 3 hours lying on the road in the sun, very disappointed with the product they sold me, it no longer has a warranty?

Comparada con una Camara 29” 1.75-2.4 real estas se ven demasiado estrechas y parecen más bien medida 27”. No son la medida que dicen. Voy a devolver.

Use las 4 y todas se picaron o se rompía la válvula
