SB ONE Boner Singlespeed tensioner

The SB1 BONER is a singlespeed derailleur instead of a classic rear derailleur

1st generation - more affordable

Very strong tension spring

Use: Bikepark, Freeride, Gravity, SlopeStyle, Pumptrack

Weight: 170g

Riden and tested by Freeride Elites LOOSE RIDERS

Recommended singlespeed tensioner tension:

REVERSE COLAB/ SB1 CT - medium load (Dirt, Street, Pumptrack)
SB1 BONER - high load (Bikepark, FreeRide, Gravity)
SB1 G3C - extreme load (Freeride, Rampage, LooseRiders)

SB ONE tensioners are attached in the classic way like shifters and are combined with Singlespeed kits for 9/10/11 speed chains (one sprocket and washers), which replace the classic cassette.

Such a solution can save up to 500g of the total weight of the bike!

A very popular gravity solution for riders riding Red Bull Rampage, LooseFest , SlopeStyle , etc.

Ideal for bike park riders , where classic gears are used minimally.

Also suitable for pumptrack, slopestyle and dirt bikes with classic dropouts (not horizontal)

Recommendation:

The manufacturer recommends using a sprocket (e.g. AbsoluteBlack, REVERSE COMPONENTS,...) designed for 9-11 speed chains ( width 11/128" ). *seller's note: a sprocket from a detachable cassette may also work (be careful of the chain falling!).

Does not recommend sprockets for 6-8 speed chains ( 3/32" width ) and singlespeed chains (3/32" width) 1/8") .
