A lot of the gadgets will come to you in the field when using the things you need on the trail. A saddlebag still comes in handy, but modern telescopic seatposts are their enemy. How to reconcile these two different worlds? Plain and simple with this slip-on delrin reduction. It prevents the seatpost from rubbing, damaging the bearing and in case of emergency, when the seatpost starts to slip due to a malfunction, it can also be used as a safety stop to keep the seatpost extended.
