    Srad forks K1 wheel?

    The caliper should clear a 320mm disc no problem. How much clearance do you have?

    As for the other bit. It's important to make sure the fork is unstressed. Screwing the spindle in the whole assembly can pinch the fork somewhat. Might affect disc centralisation. Given that the wheel should be 2mm narrower at the hub, the discs ought to be close to the inside of the calipers.

    Another issue could be disc offset. Stock TL discs for example have a very small offset. Something like 0,5mm each side. Not sure the discs you use have such a small offset, but it's worth checking.

    I guess you don't get sarcasm ;)

    Wasn't quite sure.. second language you see.

    Anywho, cool dude that Brock fella. Really into it and running a company, rare combo.

    That and the tube wall thickness are the key issues. The shock mount becomes a lever and the tube the pivot. As I mentioned before, think of stilsons on the tube, or a spanner on a bolt and it's easy to see how much force is being applied. That force is in a direction that nothing involved is designed or spec'd for, and also bear in mind that the tube which was under spec when new is now over 40 years old. It's a shit idea, based on piss all in the way of engineering knowledge or even basic physics. However, as always people are free to do as they chose and ignore what they don't like.

    It always makes me chuckle when you get the "I've done this that or the other for years and it was fine." comments. You get it on every subject from wiring, through engineering to structural design.  There's no point in arguing with it as if they didn't get it the first time round they won't any subsequent times either. The information is widely available, and these days you can even get engineering calcs done by simply inputting numbers. Still, the ubiquitous 'Bloke on the internet' will have his say and it's much quicker than actually finding the relevant information.

    There's this train of thought.. and there's the overthink everything and get very little done (my area of expertise 9_9). Learning = making mistakes.

    If you get the shocks in at exactly 45 degrees, in the triangle of the lower mount, upper mount and the swing arm pivot, the forces put on the shocks will "graph" linear as it goes through travel. It's easier to tune the shocks.

    I'm with @Gixer1460  on this one. If you want linear action the shock has to sit perpendicular to the swingarm. That way most movement is going 'into' the shock, instead of rotation the shock. With no spring or damping to limit that rotation.

    I can't see a problem with it :/ if its welded good and a gusset is behind it for support it ain't gona go anywhere !!!!!  

    With a big hole it does seem like a lot of the tube is replaced by a weld. Plus a mount that is offset from the tube.. will try and twist it under load. As well as the usual load from what the subframe needs to take on top anyway.

    A gusset that spreads that suspension load over a greater surface of tube.. seems like a good idea.

    That said.. it's steel.. and there are two shocks. If it fails it probably won't do so on both sides without any warning or cracking what so ever.
