Fat bikes are known for using larger tires but that also means they use larger tubes, and they weight more. Most fat bikes can shred some weight by changing the tubes in their tires.
We spent some time looking at different tire weights offered by different brands and we were surprised by how much difference a tube can make in the bike’s weight.
|Brand||Model||Valve||Weight (in grams)|
|Surly||.9mm XC 26×3.0/4.0||Presta||555|
|Stock||Mukluk 3 tubes 26″||Presta||400|
|Specialized||26×2.3 – 3.0||Presta||290|
|Q-tube||Super Light 26×2.4/2.7||Presta||259|
Consider Converting to Tubeless
Some of the newer carbon fat bike rims are tubeless ready but keep in mind that most aluminum rims available are not technically tubeless ready, but they can easily be converted. You won’t depend on fat bike tubes anymore and it will save some weight.
Here’s a setup video
Just don’t forget to carry an extra tube and a pump if you convert to tubeless. Pumping a fat tire tube will take a considerable amount of time, though.
