How it Rides :
The mantra as with the websites say : Steel is real.  Hard to argue this 
This Zunow is old school steel in every respect ! 
The ride is best described as “plush”. It’s a result of tubing diameter, 80’s technology and the longer relaxed wheel base geometry
Z-1 was considered a state of the art racing bike - Bottom line - a great retro ride that still thrills

About Keirin :

In Japan, a strict system of standards was developed for bicycles and repair tools. The Nihon Jitensha Shinkōkai (Japanese Bicycle Association or NJS) - now under the JKA Foundation - requires that all keirin racers in Japan ride and use equipment that meets their standards. All riders use very similar bicycles, so that no rider will have any advantage or disadvantage based on equipment.

All bicycles and equipment must be built within strict guidelines set by the NJS, by a certified builder using NJS-approved materials. The products are then stamped by NJS and only equipment bearing this stamp may be used.Frames must be built by a very limited number of approved builders. Zunow is certified for Track Frame / NJS Keirin

Since its beginning, the bicycle frames used in Keirin races have been made from chromoly steel. NJS approved equipment often sells for more than comparable equipment because of its specific use, build requirements, and limited manufacturers.. The Italian cycling equipment manufacturer Campagnolo has, though, received NJS certification.
