Small Lobo built up and this is the first time the shock has had the ring on the bottom, so previously I've been guessing/measuring to find out if it would fit. I was pretty accurate but not enough. It will work but when it bottoms out and tilts back, I think it is going to hit the 'arch'. The shock is longer than stock and the spring wider. I can't get the original spring to fit over but with some metal work I could, this would slim but height wouldn't change. The original shock sits lower and bends with the arch, so missing it. I do need to lower the trunion a bit, which will gain me a little space, maybe the medium frame is different also?
Measured stroke before I think it will hit is about 1.8", so 5.4" travel at the wheel. It would suck but I could limit it to that if I had to.
Everything else fits fine, my trunion adaption is good and it all moves like it should.
Frame with shock and all bearings etc weighs 5.7kg or 12.5lbs. The Coupe shock is 780g and the Pro 1150g.
It will fit!! I will make it work, somehow, I'm too far in now
I lowered the trunion a bit and put the shock back the correct way. This gives me more travel before the spring touches the arch. Almost full travel, I measure 2" of shaft now so it did gain me some. It might now be ok but very close at the front.
The shock looks great! I've been talking to a few people about the old team bikes and it seems that they used a coupe deluxe but with a longer stroke and a much bigger wider spring. Each one custom tuned to suit the rider. I've attached a picture of Nolvenn Le Caer's medium team bike. The length of stroke and spring looks similar to yours but without the piggyback!
