Disc Brakes on Newton Gravity FS with no caliper attachment
Hi, I've got a Newton Gravity FS Mountain Bike. It's pretty old so it doesn't have the disc brake attachment holes. I had to replace my wheel about a month ago, and ended up getting a wheel with the disc attachment for disc brakes from REI. Now that I have that, I am interested in upgrading from V-brakes to disc brakes.
Now, there is an attachment point on the frame, but it is a lot smaller than the normal disc brake mounts. I'm trying to figure out what kind of adapter I will need to buy. I found something on ebay: http://cgi.ebay.com/New-Bike-Rear-Di...3286.m20.l1116
Will that ebay item work on my bike (see attached pictures), or if not, do you guys have any recommendations?
