Orange Five shock size is 190 x 50, what would happen if I put a 200 x 51 shock on it? I assume the swing arm would hit the seat tube or someat?

It will also raise the rear of the bike slightly which will change the geometry. No idea how much as I’m not an engineer it’s a 5.3% increase in shock length so I guess by that amount.

You’ll get a steeper seat angle (but in a more permanent way).

Probably shouldn’t do then eh!!

There probably isn’t enough room to fit it in anyway, as the swingarm already runs very close to the seat tube. Not even worth trying to be honest.

Fair enough, i’ve got a crappy old manituo shock and my mate has an rp23 laying around so just thinking out loud really. Assumed it wouldn’t work otherwise they wouldn’t spec specific sizes!!
