Just a bit surprising not see boost spacing, is all. I had to convert all my 142 hubs to boost.
Yeah, about that. Rear triangle is a solid piece of 7075 Alu, machined from a single block of material. Those 6mm made a big difference in price.Just a bit surprising not see boost spacing, is all. I had to convert all my 142 hubs to boost.
Yes
So did I.Just a bit surprising not see boost spacing, is all. I had to convert all my 142 hubs to boost.
I thought the steel tubes bonded in to aluminum would raise more eyebrows, it's pretty sweet.
I can answer whatever question You have, go ahead, ask me!Pretty rad!
Is there more information somewhere? Curious about the thinking behind some of your choices, suspension design, how it's been working, etc.
Does a shark swim better than a cheetah runs?
Is dark matter real, or was it just added as a fudge-factor to general relativity and the equation is wrong?
orly
It doesn't matter if a shark swim better than a cheetah runs, because an owl flies quieter than anything else.Does a shark swim better than a cheetah runs?
Seriously, I guess I'd start with these: Why steel tubes and aluminum lugs? What were your goals with the suspension design, and have they been achieved? How's the weight? Stiffness/compliance? Plans for production, or more of a design/fab exercise?
And why don't the cables go through the bar, stem, and headset?

I've used Loctite EA 9466 and room temperature cure. I did a bunch of chemical treatments to alloy parts, and mechanical to steel tubing, as well as done some crazy cleaning of bonded areas for a greater adhesion strength. It was 2nd best option according to aircraft/military literature I've found. For the best one, I simply couldn't get the chemicals. They were all restricted due to possible use in drugs or explosives production
For the 2nd best option, it wasn't that much easier to get them, kinda expensive, doable tho.
Ok, thanks for the info! Awesome stuff you got going on here. Bravo!I've used Loctite EA 9466 and room temperature cure.

Parts after the treatment and drying (pics taken around 3:40 AM in the morning, as the solution baths were taking couple hours, and had to be done in controlled temperature/time/order and so on, then i had like 40 minutes to bond them, otherwise the bond properties would deteriorate with time). In the 2nd pic, if you look closely, you can see (or not) aluminium material grain structure, that become visible after the treatment, kinda like layers formed during rolling of the aluminium stock.
Rear triangle is solid. I've done a lot of FEA on that No internal machining. It is kinda heavy, at around 1150g. It is stiff. The biggest difference came from applying proper preload to the bearings and stiffening/bolting together the lower linkage.
Those fenders rock!
Dat head tube owl, so cool. So is the rest of the bike of course.

If they aren't, you can buy a Mullet Cycles one for 15000USD.Hey @troy are those head tube badges available on their own?
