After having the Mojo in the shop for more than two months, finally the folks a Chelsea Bikes were able to finish up my disc mount break. After having ridden it for the last two years with a disc up front and v-breaks in the rear, I decided that I wanted the whole hog. A bit more weight, but for balance, it makes sense to have both breaks have the same feel. Plus, for the winter, having disc makes a tremendous difference in the snow- no build up under the breaks or icing on the rim.
Here you can see the final product. The weld quality isn't the best. The alignment on this was super tough- the thickness of the tubes I think prevented the guy who did the welding to space the mount slight further out, creating an incredibly close spacing between the actual disc and the mount itself.
By using a set of washers, I was able to space things out just enough to make the break not rub. I guess this is what you get when you convert a non-disc break frame to rotor. The other point is that on the chain stay, there is probably 1/8 of an inch between the rotor and the frame. Thankfully the frame is stiff enough to not close the gap completly to cause rub. Makes me consider that Hope Mini's with 140mm rotors might be a beter bet.
Regardless, the break feels strong and the frame doesn't feel any different. I got an old set of Real Levers to replace the crappy ones I used before. Makes everything feel really good. I rode all over the Brooklyn waterfront, hoping curbs and riding stairs. Nice way to enjoy the 60 degree January day.
