Triathletes like to analyze their gear to no end. One thing that sometimes gets left by the wayside is the humble bike tube. 

If you need the lowdown on bike tubes, hop on over to Trisports University and check out the Beginners Guide I wrote for them.

If you realize you need some tubes, Trisports has you covered there too. Hit me up in the comments or on twitter and I’ll give you a 20% off code to use!
