More and more, twinshock and pre-65 riders are looking for more sophistication from
their bikes than was ever anticipated with the revival of these classes. Having experienced
the performance of modern bikes, and developed riding techniques to use it to advantage,
they are looking for more than the old equipment can provide. Nowhere is this more
obvious than in the suspension department.
Monoshock suspension has revolutionised the handling of Trials bikes and made impossible
hazards possible with the right amount of skill from the expert rider - and the novice
has gained from such developments. Shock absorber manufacturers are being asked to
provide similar characteristics from Twinshocks but it has been difficult to provide
the wide range of spring rate variation which is required in the travel which is
NJB SHOCKS have been developing the damping characteristics of their products consistently
to reflect the demands of their customers and now they have introduced a new range
of ‘TrikShox’ which has addressed the need for a wide range of spring rate in these
limited travel applications.
Development revealed that the search for lighter initial springing was inhibited
by the torsional resistance of the rubber bushes used for the traditional end fixings.
Bearings can be fitted but these are unhappy in the environment in which trials bikes
operate, the ingress of mud and water leading to rapid wear. Therefore, NJB SHOCKS
has commissioned the manufacture of special low-friction fixings to overcome this
problem and allow the softer initial springing riders want.
Riders are individual in their requirements, so a degree of adjustability is needed.
‘TrikShox’ provides adjustments for preload, spring rate and the proportion of soft/hard
travel required. Two grades of damping are also available with the new’Supersoft’
damping being particularly popular in rocky areas.
They are available in lengths from 330 to 390mm (13 to 15.35” in old money) with
fittings to suit most popular Pre-65 and Twinshock bikes.
