    I bought a Homegrown Factory XY back in 1998, rode it , loved it, sold it.  Yeah the fork was a bit much, but long travel options were a bit more limited then.

    Wanted another one for years and lucked out recently.  Found a used BBO Frame on eBay for a steal.  Decided I was tired of the full suspension GT I was on so I stripped it of its XTR parts, added a few odds and ends and now I have my Homegrown again.

    After riding it this past week in the cold and snow I decided it’s time for a rear disc to go along with the front I’ve had for years.  Obviously this year didn’t have that option so it was time to get creative.  I researched the various aftermarket adapters out there, but not a huge fan of any.  Fortunately there’s really no warranty left on the frame, and I’m not afraid to modify it.

    I started with the intention of makig a bolt-on bracket to mount the caliper, but could see no good way to do it without ending up with a huge, bulky, ugly bracket.  After a couple hours of messing with it, I decided to make a weld-on tab.  Fortunately I had a nice piece of 6061-T6 and a machine shop at my disposal.

    Working with very precise tools (also known as paper, cardboard, and a pen) I had a bracket roughly designed.  I knocked the holes in for the 51mm ISO standard, shaped it to clear the caliper and then began the fitting.  It took some time to get the caliper just right,  but it’s pretty darn close now.  

    After cleaning off the 1/4″ thick paint I found clean aluminum underneath.  Layed the new adapter on there and burned it in with some 4043 filler to allow for some flexibility.  I was surprised with how well a 13 year old abused frame welded.  The welds aren’t perfect, but I also don’t do aluminum all the time. 

    I know what you’re thinking, how is it going to hold up?  Honestly, I don’t know.  The wall thickness of the seatstay is fairly thick, as is the dropout itself.  There’s only about an inch of the bracket on the stay, so unless the entire dropout deforms it should be good to go.  Also, it’s an XC hardtail.  The rear brake isn’t really going to see all that much stress.

    Just thought I’d share.  Sorry for the long post.

    If anyone has ideas on how to come remotely close to the BBO paint, I’m all ears.  Not taking it to a paint shop, I know that much.

    I say polish up the unpainted area to highlight the cool mod Cool

    I like your creativity and applaud the job well done.
