Due to popular demand I am gonna have a go at documenting a frame build.
Note: this is not a how too, I will not go into the minutiae of brazing, mitering, measuring, fit and all the shit that makes framebuilding harder than it looks. If you want to build your own frame go out and do the legwork, It was over a year of research and practice before I put my arse on a bike I had made.
This bike is my no excuses winter/commuter/travel bike, I intend to ride to work every day this winter (~37k return) and with this bike I shall have no excuses not to ride!
The frame will be made from KVA stainless steel, damn expensive stuff, and damn hard to work with, it will be a 60x58cm with:
-S&S couplers for travel duty
-Brake bosses for Paul Racer M brakes
-fender and rack mounts
-internally routed wires for the front and rear dynamo lights
-entirely made from stainless, except the fork, which will be replaced with a stainless one when KVA release their stainless blades
The whole thing will be peened with glass beads to give a nice satin finish
First things first is to brainstorm how I wanted the bike to function and handle:
-able to carry small loads
-able to break down easily for travel
Taking this into consideration I have built a stable, low centre of gravity road bike with nimble handling characteristics coupled with good road tracking and versitility.
- 75mm BB drop
-430mm CS length
- 375mm A-C fork for clearance with a 45mm rake
It is important to draw up even just a sketch to make sure everything works together. This is a 1/2 scale drawing to get everything to fit nice
You can see two big 660mm squares on the drawing, these are the fit templates for packing the bike down in an S&S case, the yellow highlighted zones are where the couplers can be installed.
Right, so stay tuned for progress on the build, with piccytures, it will either start this afternoon or tomorrow morning depending on how I go finishing the bike that is before it on the list.
