Here’s my first frame that I designed and made last summer.

Bronze welded with mixture of Reynolds 853/631 main tubes.

It does have two bottle cage mounts but I like to run a bumbag!!

Really well done. Weight? travel?

Super nice, this looks a bit like a full suspended ESD (though not as slack).

But I think you're limited to shocks without piggyback (or short ones).

Thanks for all the kind words! I've uploaded a few more images onto my profile of the build.

My favourite detail shot (ignore the cable tie as I should be fitting an internal routed post soon!!)

The full bike came in at 15.8kg but it's running a coil fork and shock so it was never intended to be a lightweight. I chose the wheelset & tyres based on their weight as I believe that's a lot more important to how the bike feels than overall weight. The fully welded chainstay yoke is over 400g on its own so there's room for improvement there..!

I do have some nicer countersunk washers/bolts to replace the hardware that I need to get round to fitting as that will improve the overal quality of the build. Likewise, the aluminium rocker was only waterjet cut as I wanted to make sure I'd got my motion ratio right before commiting to a CNC'd part.

When I started the design process, I really liked the idea of having a continous line from the headtube to rear axle and I was against having any bent tubes so it took a few loops to get everything packaged. I always intended on fitting a coil shock and the Cane Creek Inline seemed like the perfect match so that's what it was designed around.

lots of pretty bikes with that uninterrupted line along top tube and seatstay, good choice. 15.8 kg is a totally reasonable weight, especially for a v1 homemade steel brazed full sus. Lots of bikes on my group rides are heavier.

Seeing people making viable brazed full sus at home is really inspiring.

I designed the jig to be simple and compact as I’m working out of a tiny shed. I turned all the cones on a hobby lathe and had the rest of the parts water jet cut. It was designed to accommodate anything from a small road frame to a large mtb incase I decide to make any other frames!
