I love the little starling details on the gussets! They are very elegant and do remind me of my old BMX frames. I run all my cables through the gussets except for the brake!
As a former BMXer... It feels awkward that you may have to explain gusseting steel tubing to MTBers lol. Few ways to do it but the kinda classic bicycle way Starling does it is a treat to look at. Adds a little flavor. Arguably little more fun that just adding a chunk of extra metal on the top sides and down sides as simple, modern designs do.
To fix to headtube as well is much harder to do in manufacturing. It might add a bit more strength. But the design we use works well; we've had no head tube failures.
It's S275 steel. The strength is actually not that important. It's role is to transfer shear and all steels will do this equally well. It's failure mode would be by buckling, so again, steel type is not that important. But we've seen no failures of gussets, so the steel we use is plenty strong enough...
Love your designs. Wish your stacks were higher on your big frames. 6'6" dudes like me need a lot more attention to detail on these long reach frames. 648 is crazy low.
Stack is mostly a function of fork length. We have 130mm headtube on our XXL frames. We could go to 140mm, but any bigger and the bikes start to look really ugly, a bit like a gate!! So we think for taller riders who want more stack, a high rise bar is a better solution. There's plenty of reach, so you don't risk making the bike too short with the higher rise bars. Also, bar height is real personal preference. Some people like high bars, some low. It's easier to go higher with bars, than lower. So we tended towards this solution.

Nice one, Joe! (and thanks for the plug on our FEA work too!).
I, for one, think they're quite pretty! Especially the new assymetric ones. It gives the frame a rather unique profile. 😊

Love your gusset design!
Nice Video, why do you don‘t join the gusset with the headtube? Are there any pros or cons for doing this?

I do enjoy them. Is the gusset made out of 4130 or is it a different grade of steel?

@@joemcewan2950 Cool, thanks for the detailed response.
