Sea Otter 2016 – Bontrager Tires, Wheels and Dropper Post

by Brian Mullin on April 23, 2016


Bontrager’s LINE product suite has some dandy new stuff for this season including the trick Drop Line Dropper Post, 35mm bars (carbon and alloy) and alloy stems, Line Pro flat pedals, XR4/SE4 and Barbegazi fat and Chupacabra Plus tires and finally LineXXX and KoveeXXX carbon wheels.

Drop Line Dropper Post

Their new Drop Line dropper post uses an Air sprung hydraulic locking cartridge and has infinite adjustability within the travel range. To prevent shaft rotation and wiggling it has an internally keyed chassis design which provides a secure and stable saddle platform. The internally routable post uses remote cable actuation with an under bar lever, comes in only a 31.6mm diameter and 100, 125 and 150mm of travel lengths and costs a reasonable $300. The Drop Line has a well thought out design for cable positioning and how the cable clamps at the remote so that installation and removal are simple and easy.


During some twiddling with the Drop Line at the show, I found the under the bar remote had a nice feel and good actuation and the upward movement of the saddle was swift and powerful.

Tires and Wheels

They have several tire models with highlights to the XR4 Team Issue and SE4 Team Issue. The tires come in 2.4″ widths and 27.5″ and 29″ sizes and my favorite the semi-fat 29er in 2.55″ width and all of the tires retail for $69.99. Both tires tread is fast and grippy and made with a softer compound and are Tubeless Ready (TLR).
