Likely not compatable. i haven't checked the actuation ratios of box, but as far as i know the box 7spd dh is not compatable with sram dh 7spd. I would stick to using box with box tho

Correct, Box uses a different cable pull that is not compatible with other brands.

from Box's website FAQ:

Q: Is the Box Three Prime 9 Derailleur compatible with other 9 speed components?
A: No, traditional 9 speed systems use a Cable Pull that is not compatible with Prime 9.

I plan on picking up one of those derailleurs and trying to make it work with my XO 9 speed grip shift.
Sometimes you can mod the cable pole ratio with spacers.

No Box stuff on there, but info that should be useful.

In terms of the box stuff a pretty decent article...
https://bikepacking.com/gear/box-prime-9-review/
The takeaway is that it seems to be a closed ecosystem much like the advent stuff from micro shift. That said I’m sure there’s some shed-ineering that could get this to work, just look at the shimergo abominations.

Has anyone had any experience with stripping the paint off of fork crowns and polishing them up? Im just wondering how much of a pain in the arse it'd be and how long the aluminium lasts before it goes dull again? Love the look and I'm not against putting a good bit of elbow grease in for it but I'm worried it'll be a never ending battle to keep it looking half decent if I actually ride the bike a decent amount

Polished a set of marzocchi z1s many years ago. They went dull after a few months. Actually really easy to polish though. Takes maybe half an hour to get them to a gleaming mirror shine.

A "polymer" type car polish helps seal out the oxygen and keeps it fresh for longer.

Sweet! Tbh I was imagining it would be loads worse than that so that's good news. Obviously I'd strip the while thing down for the initial paint strip procedure but for just a top up polish with a rag could I get away with doing that with it still on the bike do you think?

Thats sounds like a very handy tip, will definitely be looking into that

Ok, thanks for all that have commented, clearly I should've gone and read the FAQ more closely.

Automotive paint shops often recommend against polymer polishes because they're too good and complicate the process of touching up or repainting when factory paint is now so good that it doesn't need as much protection.

I don't buy that argument, as I've never repainted a car, but I've had paint get dull after many years. In any case, it speaks highly of how good a polish can be, which is perfect for our needs of protecting a raw aluminum surface.

Before I go out and buy a new chainring and cassette I wanted to come here to get a second opinion. So I replaced my chain after some shifting problems and after installing the new chain and dialing in the limit screws it was shifting well in my bike stand. However, when I went out for a ride and pedal hard a loud noise is coming from the drivetrain also when I pedal full out the chain jumps. I believe I need to replace the cassette and possibly the chainrings, what do you guys think?
