Gareth’s small wheel disk conversion

Gareth at Essendon Cyclery http://www.essendoncyclery.com.au/ aquired a small wheel Mojo and as you do, decided it would go better or stop better in this case, with a set of disk brakes and of course a pair of very nice Chris King hubs. Gareth removed the original dropouts and suplied me with both the new dropouts and the disk tab to braze in. We put the dropouts in forward facing to reduce the risk of pulling the wheel out under braking.No problem there

In typical fashion though when it came to the disk tab, something wasnt quite right. Clearly tabs are designed with the idea that the edge of the dropout is in line wth the inside edge of the fork blade rather than it being centred in the blade like this one.I sent him off an email with these couple of pictures and a couple of options

We could either move it to the centre and put a couple of spacers between the tab and the caliper, OR I could make up a new tab with longer legs and a bend in it to place it in the same plane and do away with the spacers. Gareth went for that idea.A bit of bandsawing,drilling, bending and brazing later, everyone was happy.
