new frame, same addiction

I bought a far east frame for a few money, with his own carbon fork.
It comes with a soft gold anodizing and with many rough welds.
anyway it seems strong, with a quite tight geometry and not so heavy.
I'm cooperating with a guy, Christian, that builds amazing motorcycles: Plan B Motorcycle, and he use a chemical way to engrave aluminium. The aspect is really particular and we think to use that method even for my new frame, but before I have to prepare for the belt!
Yes, I'm yet addicted to the belt drive, so, after lathing a little the seat of the lower bush, I cut the oblique tube of the rear stay and I put an aluminium hanger with two M5 screws.

Now it's time to weld, then I would like to grind off a little bit the "oriental" welds and engrave.
I'm looking also for spokes, but with high flanges hubs and 88mm's deep rim I need shorts spokes.




The fork had the anti-slippery tips, no good for a fixed bike!

inglourious bastard

I'm looking for a magnesium wheel, maybe broken or to throw away (otherwise it costs much more than a used dogma...!) to redo the left dropout, and now the frame is in my office as a "post war sculpture"...

by the way I have noticed that Continental is making a good belt drive for bicycle!
 they haven't yet enough cogs and pinions, not yet many lenghts for the belt, but this means that there isn't only the Gates CDC System.




who filled with glue the crack? 
eeh, maybe a not properly honest reseller... 






the closeup of the welded dropout. while I removed the screw I heard a noise like of broken biscuits...
Magnesium couldn't be welded to aluminium, a good lesson to me!

say hello to the Hyper

I'm preparing the Hyper for another owner, maybe someone who will love and use more than me...

I really don't like so much the cyclistic specs of the Hypermotard, it's too high, too soft in the front-end (due to the huge Marzocchi RAC 50, a very bad fork compared to the cheap showa 41 or 43mm... ) but with a very good braking system and, thanks to the 2 valves-air cooled engine, it's really funny.
I'm also working on a cafè racer, based on a ducati 999. I went in a circuit with the 999, and I found it intuitive, comfortable and with a good dose of hp.

the dogma without magnesium is died!

The welder told me that wasn't a problem weld the holes and the crack on the frame and suggested me to introduce an aluminium plug in the seat tube to reinforce the cracked area.
So I done the plug and the new dropouts, the right is screwed and the left one to weld on.







But... the frame is in magnesium, and the dropouts in aluminium, so it's impossible to weld the frame with the left dropout. I'm looking for a piece of magnesium, but it's really really difficult to find. 
I asked to a local aircraft factory, but due to the high flammability they didn't use from far.

In conclusion: if I don't find the magnesium to do the left dropout, the Dogma is died!
I'm imagining  to weld by my self a full aluminium frame...!
