Manufacturers.......... There surely is....... Many of these rear AIR SHOCKS on many mass produced bikes.
But we live in a contrived world. Were nearly everything is a paradox (Something negative, when we expect something positive, something good), a contradiction, or a trade off (The rear sus works, but not as good as we'd like it too).
I don't weigh alot (Less then 11 stone) and I don't ride really rough terrain, to give you an idea, riding my local terrain I'll get 8cm travel on my suspension front forks COIL/ELASTOMER ROCK SHOX JUDY II. Now knowing manufacturers, the MAX of these rear air shocks, maybe too LOW.
What do I mean? Over the next few years, we are bound to see further refinements to current rear air shocks, after being unimpressed by what's on offer at the moment, I know if I just bought a bike from the internet just on reading the specifications, I'm bound to be disappointed by the ride and too soft travel of the air shocks. Unlike hardtails whereas GEOMETRY doesn't differ much, just groupset, forks, frame weight/rigidity and price.
In my local bike shops, the full sus xc MTB's (Ghost, GT, Cannondale, Kona, Cube, Scott, Carrera) they don't have 16" (Or less) , just 18" or larger, and the rear shocks are too soft:
~ I ask can they set them up, they say what size you want, 16"
~ I ask if they have a smaller model, the reply is NO.
~ But we can order a 16" or small, but only if you pay for one here and now.
Obviously I'm not going to buy a bike if the shock is too soft, and they won't set up the larger model rear shock to give me an idea if it would be OK for me, because it wouldn't be the size I'd get.
A viscous circle, perhaps.
I could drive to non local bike shops that carry/have 16" or smaller in stock, but these are 150 miles each way.
Conclusion: That's along way to travel, to just sit on a bike!
Ha ha, no joke intended.
