Previously under our radar, it wasn’t until this year’s EUROBIKE that the Italian rear shock specialists, EXT RACING SHOX, were revealed to us along with their two new steel spring shocks. Design for enduro, the STORIA is reputed to unite the advantages of a steel spring shock with the featherweight of an air shock – and weighing in at 620 g (including spring), it already looks like the lightest shock on the market. Equally as promising is EXT’s newest downhill shock, the ARMA, whose array of set-up options mean that it can be tuned to suit any rider.

Based in Northern Italy, Extreme Biotec have been creating damping systems for motor vehicles for more than 55 years, kitting out a host of two to four wheeled vehicles from off-road rally cars to Formula One. Over the past three years, they’ve extended their repertoire under the name EXT RACING SHOX to develop and manufacturer mountain bike shocks, and their goal is to become the industry leader with their distinctive dampers. While we can only ascertain whether the STORIA and ARMA have the capacity to perform at the highest level after vigorous tests, here’s an introduction to the products:

Links der DH-Dämpfer ARMA und rechts der Enduro-Dämpfer STORIA.
Left: the downhill-specific shock ARMA. Right: the enduro Storia.
Der aus der Aluminiumlegierung 7075 T6 und Titan gefertigte STORIA soll mit einem Gewicht von 620 Gramm (inkl. Feder) der derzeit leichteste erhältliche Stahlfederdämpfer sein. Zusätzlich verfügt er über ein Lockout-System, um so das Klettern zu erleichtern.
Created from 7075 T6 aluminium and titanium, the STORIA tips the scales at 620 g (including spring), which renders it the current lightest spring shock on the market. A bonus: the STORIA features a lock-out function to ease climbing.
Sowohl der ARMA als auch der Storia sollen dank ihrem niedrigen Reservoirdruck im Ausgleichsbehälter ein äußerst geringes Losbrechmoment bieten.
Thanks to the low pressure in their piggybacks, both the ARMA and the STORIA are sensitive enough to absorb the small bumps while diverse enough to take the big hits too.
Der DH-Dämpfer ARMA verfügt zusätzlich über eine extern verstellbare Endprogression.
The ARMA downhill shock also allows external adjustment of your end progression.

STORIA and ARMA from EXT RACING SHOX are due to be in shops from January 2016. The ARMA, weighing in at 690 g (including spring) will come in a 241 x 76 version, while the enduro-specific STORIA (620 g including spring) has been designed as 200 x 57.

Both rear shocks are set to retail at 725 € plus VAT, including two springs from SA RACING SPRINGS.
