It's been awhile since I posted, but I'm trying to get back into shape and drop a few pounds so the Homegrown's are coming to my rescue.
I've found a few riding buddies and was tired of getting dropped because they're all on gravel bikes, so I decided to convert a Homegrown to gravel duty.
Stock 19" 1998 Bass Boat Blue with Hayes 22mm mount. Threw on some 29er disc wheels with 700x35c tires and had plenty of clearance. Next was fitting a rear caliper. I wanted to use drop bars, so I began the hunt. Ended up finding used Shimano hydraulic 2x11's. That required the use of a Shimano caliper. First tried the common A2Z adapter, but not even old IS mount XTR calipers wanted to fit. Next tried a Magura IS mount caliper, but the lever and caliper didn't like each other with regards to fluid flow. Lastly decided to go with a new style flat road caliper with a custom made adapter.
The adapter design was very simple and is an easy install. Unfortunately for me was the cost to get a machine shop to make one ($145). Oh well, small price to pay to get this fabulous frame updated with modern tech. If anybody is interested in the .dwg file I will gladly share it for free. If the cost to manufacture these could be reduced I would be selling them myself, but I have my doubts that enough demand would exist.
Update 2021: There has been demand for these adapters. I get them 3D printed out of Stainless Steel now. USA buyers are charged $60/ea which includes USPS Priority Shipping. International Buyers are charged $70/ea which includes USPS First Class Shipping. I will try and keep these in stock. Message me directly if you want an adapter and I will give you my PayPal address. PayPal is currently my only form of payment accepted. Thanks All,
