I bought your fixie frame for $99, but found it difficult to purchase the necessary parts to build out the bike from your site, since I did not know the correct sizes to purchase. I ended up buying the Aventon fixie groupset for $160. I recommend building a groupset package that can complete your bike builds with handlebars, headsets, cranksets, peddles, a seat post and clamp, and bike seat. The Aventon kit did not come with tires or an inner tube, but that could be something to consider. Some of the Aventon parts did not fit the frame, so I had to purchase separate parts to complete the bike at my local bike shop after giving the build a try myself. Hope this helps!
