SB ONE Boner LOOSE RIDERS Singlespeed tensioner

SB1 BONER is a single-speed tensioner instead of a classic rear derailleur

1st generation – more affordable

Very strong tension spring

LOOSE RIDERS edition (LRGA logo on the front)

Use: Bike park, freeride, gravity, slope style, pump track

Weight: 170g

Tested and approved by Freeride Elites LOOSE RIDERS

Recommended load for singlespeed tensioners:

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 chainstays are attached in the classic way as crossovers and are combined with singlespeed kits for 9/10/11 speed chains (one sprocket and washers), which replace the classic cassette.

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

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

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

Also suitable for pump track, slopestyle, and dirt bikes with classic dropouts (not horizontal).

Recommendation:

The manufacturer recommends using a sprocket (e.g., AbsoluteBlack, REVERSE COMPONENTS, etc.) designed for 9-11 speed chains (width 11/128").  *Seller's note: a sprocket from a removable cassette may also work (beware of chain drop!).

Sprockets for 6-8 speed chains (width 3/32") and single speed chains (width 1/8") are not recommended.
