In most cases the Bontrager Standard tube will do the job just fine, striking the right balance between weight and puncture resistance.
If you really want to trim the weight off go for the Lightweight version, but these are more prone to punctures. The Latex tubes also offer a weight-saving, and a supple ride feel, for a super-smooth ride.
If avoiding punctures is the priority and weight isn’t an issue, use the Self-Sealing tubes for ultimate protection.
Unconditional Bontrager Guarantee - all Bontrager tubes come with a 30-day trial period, if you don’t like it, return it for a no-quibble refund.
