Onza “Tensile” Freewheel: Out Of The Box
April 11th, 2008 by Guitar Ted
Onza: The name conjures up images of white tires, bar ends, and funky elastomerically sprung pedals. However; Onza isn’t in to that anymore. They have been busy the past few years doing business in the trialsin market in the U.K. One of their products caught the attention of J&B Importers who thought single speed freaks would appreciate it. A quick engaging, tough, durable freewheel.
This is the Tensile 18 tooth freewheel, (which is also available in a 16 tooth model) and it has some cool features. The freewheel spins on two sets of ball bearings encased in a hardened chromoly housing. The freewheel engages with two sets of three pawls ratcheting in a 20 tooth outer ring for a total of sixty engagement points. Quick engagement anyone? The housing has a hard nickel plating for durability and corrosion resistance. The Tensile freewheel is also fully user serviceable.
I have installed my 18 tooth example on a 29″er single speed and I will be testing it all summer. It replaced an ACS Claws and according to my digital scale, it weighed exactly the same. Cool! I’ll check back with some updates soon.
The Onza Tensile freewheel is available in 18 and 16 tooth configurations now and has a MSRP of about $70.00. Check with your local bike shop for availability.
