Damn, that’s a long ass bike. I’m the same height and found a 488 reach too long. Can’t imagine 515.

Sweet spot is 460-470 for me personally depending on type of bike and riding.

Looks sick though!!

im 5'11, with limbs of someone 6'3. saddle height is 785mm.

the seat tube angle and low stack height has a lot to do with how this bike feels. at sag the sta on this bike creeps towards 79 degrees. my dual susp reach is also 515, and it feels a lot bigger because of the 76 sta, and 35 more mm of stack height.

ive had a couple people sit on this hardtail that normally ride 480-490 reach bikes and thought it felt 'surprisingly normal'.

Anyone got experience with 6061 aluminium and brazing it?

trying to wrap my head around building a single pivot dual susp. so far the most daunting task seems to be trying to learn fusion360! built the shock in fusion first as it seems to be a good first project. eye to eye set to 230 mm, and max compression set to 60 mm.

the plan is to build something that doesnt require any machining, based off of the curtis xr650 - but with 29" wheels.

probably going to use a headset and steer tube as the pivot.

anyone else tackle a dual susp?

Hey Guys,
I've been a long time lurker. Only now started in on actually attempting to put my ideas into CAD. My big issue is finding standards that I can model parts off the shelf parts from. Where do I go to find CAD drawings of forks, shocks, hubs, etc? Or are there documents out there that give standard dimensions??? I just can't seem to find where to start. Seems like a dumb question but I just can't figure it out!

Fox, Rockshox/Sram, and some of the framebuilding suppliers have relatively easy to find part specifications/drawings. Shimano's drawing are for the most part much harder to find but they do also exist. You can also measure the actual parts on your bike.

I drew mine in Autocad Inventor. Only the front in 3d but i could at least see that it all would work Smile
Ridden the bike for about 1500 kilomerers now.

Got some dropouts laser cut through Fractory which I'm pretty stoked on. Files arrived yesterday so pretty much ready to start!

Hi,
Heaps of stuff here https://grabcad.com/library?page=1&time=all_time&sort=recent&query=mountain%20bike
Just double check a few key dimension before you go ahead and manufacture.

Fractory advert keeps popping up on my Instagram. How were they? Also how much did this order cost?

Super happy with them, barely need any smoothing or touching up. Tiny marks from the last bit of the cut but pretty clean otherwise.

They do instant quotes on their website, dunno if you've used 3D hubs or Weerg but it's pretty similar. Good to have a play about with different ideas/materials etc. I've tried a few things and the minimum order is around £70-80 plus shipping.
These are mild steel but you can also get stainless and aluminium. I think they can do stuff like countersinking and threading too.

Got a few spare if anyone's after some...
