The Thomson Dropper Covert remote is one of the smallest and most ergonomic levers on the market today.
The lever works on the side of the handlebars and is shifter friendly.
Works with Covert and non-Covert cable actuated posts alike using a grub screw to firmly hold the cable in place.
Cable tension can be adjusted from the remote meaning removal of the post from the frame is not necessary to tension the cable.

You want the increased control a dropper post gives you but you had to give up your Thomson post to have it. Not any longer, you can put your Thomson post back on the bike! Our cartridge based system is designed to have the longest service life in the industry. If repair is needed it is fast, affordable and simple. Every single component is the best available. Custom made Norglide bearing bushings, custom made Trelleborg O-Rings and seals, Thomson saddle clamps and fasteners, Motul Oil. This is the drop post good enough to be called a Thomson Elite.

Side mount of actuation mechanism means we can keep all the critical dimensions of the Thomson Elite cradle, bolt and clamp geometry. One piece forged inner post for strength and reliability, no joint to loosen and fail. Actuation is by cam so rider gets smooth, variable speed and height without resorting to a complicated, damage prone hydraulic actuator; no bleeding required.

Return speed is damped in the last 15mm of upward travel to be gentle on your “seating” area!

The Thomson Elite seatpost is the standard by which all other seatposts are judged. Forged clamps, integrally machined head, and an elliptically extruded 7000 series aluminum body have made the Elite and the Setback Elite the industry models for strength, light weight and ease of adjustment.

Over 40% stronger on ultimate strength test than the strongest production seatposts on the market.

Lightweight – approximately 188 grams (250 length) for road bikes and 228 grams (330 length) for mountain bikes. Natural ellipse bore inside tube for optimum strength to weight ratio.

The Masterpiece is Thomson’s ultimate seatpost. It combines incredibly light weight with the characteristic strength and function of a Thomson. Masterpiece seatposts weigh approximately 40 grams less than an Elite seatpost of the same size, while maintaining high strength and durability.
