Shock absorber 41"
Limited availability of only one pair, payment ONLY by bank transfer. In case of order with paypal payment the same will be canceled with Paypal fees charged to the customer.
The pair has signs of assembly because it was used for testing, but it is fully functional.
Reinforced bitubo pressurized rear shocks, fully Made in Italy, custom, pin/pin mount, 41"* all open length, 60mm body and 20mm stem.
The shock absorber is recalibrated and serviceable in every part.
Each Competition60 shock absorber has the following features:
- T.I.G. welds for maximum strength and refined aesthetics;
- double mechanical steel tube lapped internally, painted with epoxy powder and phosphated to prevent corrosion, the outer tube has a diameter of 60mm and a thickness of 3mm to withstand shocks, in case the body gets dented the shock absorber will continue to function normally;
- steel rod diam.20mm coated with CrVI free hard chrome with tolerance according to EN ISO 286-2
- polyurethane bushings very resistant to deformation and wear, they are molded with 80 shore thermoplastic polyurethane specifically for automotive use inacceptable to grease, oil and fuel;
- sintered internal components for maximum control over wear-free calibration;
- graphited Teflon sealing band to improve the smoothness of the suspension; compared with cast iron bands, they are much quieter.
- dual polyurethane and steel limit switches to stop rebound travel in a controlled manner and not burden frame and bridge attachments;
- ROTHEN shock absorber oil specially designed for off-road use with high viscosity index that ensures smooth calibration up to 200°C essential for heavy use such as races or desert raids;
- double adjustment of rebound and compression calibrations at both high and low speeds with translation reed valves preloaded with star springs in compression and coil springs in rebound;
- double seal with o-ring and oil seal with metal base, the high quality of the seal makes it possible not to use rod seals which in the long run create dirt accumulation and damage the shock absorber, any debris that settles on the stem is cleaned by the double lip of the metal oil seal;
- calibration on a 10-speed test bench, from 5 to 500 m/s to have the perfect calibration under all conditions.
HM4X4 shock absorber overhaul is guaranteed at a cost of 50 euros each.
AIR DRYED pressurization is an innovative two-stage pressurization technique that allows pressurization with inert gas after creating a high vacuum, completely extracting air and moisture inside the shock absorber so as to minimize the phenomena of oil emulsion and rust creation that moisture inside a non-pressurized shock absorber inevitably creates.
In addition to enhancing the performance of the shock absorber, Air Dryed pressurization greatly extends the life of the shock absorber and ensures consistency of calibration even after years of use.
*It should be noted, since this is a handcrafted shock absorber, that the measurements may vary by a few millimeters due to the thickness of the bushings, washers, softness of the internal limit switch or welds, the measurements shown are to be considered +/- 5mm.
