Hello everybody
Much like the universe in which we all reside my ‘collection’ seems to keep expanding in every direction all at once.
A recent Yeti SB66 purchase means my previous ‘jack of all trades’ 2013 Orange Five AM is about to become more down than up focussed.
The trusty Fox 34’s are being swapped out for a set of bargain Boxxers from CRC but the question is what to do at the back?
As a serial tinkerer I’ve chopped and changed many forks but realised I’ve never swapped a rear shock.
From a few searches it appears the size I’m looking for is 190 x 50 (sound right?) and I want a coil for beefiness.
I’m a substantial lump so need a tougher spring too I believe?
All thoughts, comments and corrections greatly received.

Just a thought, but is the leverage ratio on that bike suitable for a coil? It might be, but equally it might not be. If it’s not you’ll find yourself blowing through the travel horribly.
Yep - I don’t know what leverage ratio means.
Sounds like band name to me!
How does one check?

Would it work?
The Five has a flat leverage ratio - it doesn't get any more progressive at any point in the stroke. This doesn't matter with air shocks, which are naturally proressive, but it can cause issues with coil shocks which generally aren't.
The only answer is to run a progressively wound coil, but these are few and far between at the moment.

Putting a Boxxer on a Five AM? A 200mm DH fork, on a 140mm trail bike?
As much as a bargain as I’m sure it was, that fork will ruin that bike. Either just it’s handling, by raising the front end/BB and slackening the HA & STA by about 2.5-3 degrees, or by tearing the head tube off on a big landing.
Some good points in this thread from 9 years ago.

As someone suggests in there, I'd give Orange a call. Used to see those bikes about with coils though. Could have sworn Rowan Sorrel used to run a coil in one 🤔
I’ve just put a coil shock on an orange alpine. I’m also a substantial lump. Best change I’ve ever made to the bike. Progressive spring from cane creek, no bottom out issues, smooth as. Only issue for you would be the spring rate you can go for with a shorter shock stroke - my shock is a longer stroke than yours so gives me a lower leverage ratio, and I still needed the heaviest spring available. Get on TFTuned website and see what spring their calculator recommends - some quick calcs if you’re 110kg kitted up, bike is 140mm travel, 50mm shock stroke, you’ll need a 700lb spring, which I doubt you can get in progressive form.
