There was a time that it was thought that suspension stem would revolutionize the bike industry. Predating most suspension forks, various linkage and parallelogram equipped stems from companies like Girvin and SoftRide graced the front end of rigid mountain bikes. As the elastomers dried up, so did the suspension stem’s popularity. TransX is revisiting the suspension stem concept, but with a much different approach. Instead of trying to provide actual suspension, TransX is just looking to take out the road vibration with a hinged stem that offers +1, and -2° of vertical movement to absorb vibrations. As far as we can tell, the Antishock technology simply relies on a mechanical hinge with the upper and lower steerer clamp bolts built into separate pieces of the stem. A hinge pin then connects the two, with what we’re assuming is some type of vibration absorbing material in between. In spite of the additional feature, the stem will still weigh in at around 200g for a 100mm.
The 6061-T6 aluminum stems will be offered in 80/90/100/110/120 mm lengths in April 2014 through their OEM clients with a suggested retail of € 99.00 (~$135).
