Could anyone with an AM9 or similar (doesn't matter which size) take a few measurements for me please? Need to get some things ordered ahead. Thanks in advance!
1. Distance between the outer edges of the seatstays at the wheel rim, and the same for the chainstays. Also the distance between the inside of the rim and the inside of the seat tube. These are for fitting a D lock at home as part of insurance compliance.
2. Chainstay circumference. This is for a neoprene chainstay protector which come in sizes 70-100 mm, 100-125 mm, or 125-140 mm.
I'd do it for you, except mine is a v1 and the clearance has since increased. Ensure any responses you get are from owners of the v3.
If you would consider an alternative chainstay protector, a road tire with the beads removed makes a more durable protector and you can make one for free.
Thanks. I did wonder about the versions but figured any would be close enough. I've chosen the model, need to choose the shortest from 130/190/260/300mm while remaining reasonably versatile for the future.
I've no road tyre to hand, and I don't mind paying a small amount for the tidiness of a fitted option (as long as it doesn't have logos plastered all over it, like so many do). I also considered 3M 2228 tape, but didn't fancy sticking stuff to my new frame.
Sensible on the lock and fair enough on the chainstay protector. You can almost always find discarded road tires at bike shops, if you want to pursue it; if not, it's not like the neoprene option is very expensive for a little convenience!
The difference in the requested dimensions from v1 to v3 could be as much as the difference between any mountain bikes, so if the difference between v1 vs. v3 won't affect the purchase, you can measure almost any mountain bike.
No, it's just that I've decided on a combination of chain and D lock. That Oxford chain with padlock was the cheapest solution I found for satisfying insurance. Looking beyond ticking that box, at security (10mm chain is bolt-croppable) and longer-term use I figured I may as well go for a stronger and more flexible solution straight away.

AM9 V3 large is 117mm at seat stay, 124mm at chain stay including the lizard skin wrap around protector. As a suggestion, get a ring camera installed in your lock up, got mine set that it alerts my phone if there is any movement in the shed. Also got and alarm fitted too, can't be too careful! Was also thinking about wiring the padlock up to a tazer but not sure on the legalities there!
I’m considering for bike park days either fitting the 160mm airshaft (not keen on) or maybe using the reverse components to slacken out the HA.
Concerns I have
160mm I believe is a warranty problem, also slacker seat angle and higher bb. Additionally a bit of a faff to change for just a one day trip. Pros though however bit more squish and slightly slacker head angle
Reverse components is only a .5 deg difference, doesn’t change available travel but is also slackening sa and raising bb (probably minutely) but pros is super easy to add and remove.
The spacer will increase stress on the frame more than the additional travel. Warranty terms may not explicitly prohibit such spacers, but if the warranty is your primary concern, check with Bird, as they both may have the same result.
