The only thing around here that is slower arriving than tomorrow is me. I did get the back wheel off the tri car a couple of days ago and managed to get the hub adapter and sprocket changed around. I can't say enough good things about the Sportsman Flyer hub adapter but brace yourselves because I'm going to try hard to.
When I bought the motor from Rick at Rick's Rides I asked him what sprockets he'd used on his bike. Since Manic Mechanic doesn't make custom sprockets I had Rebel Gears make one for me and since I couldn't find out where I'd put the paper with the gear ratios I took a chance and was ten teeth off what I needed. I ordered sixty two teeth instead of the seventy two I needed. My thought when I saw that are best kept to my self but I will admit to doing the "Not happy dance." Fred Astaire and Ginger Rodgers would have been proud.
I put off doing anything for the summer and then I became sick and didn't do anything for a long time. I visited the Sportsman Flyer site when I decided to get the pedal crank assembly. I looked at the hub adapter and saw that they did custom sprockets and when the time came I went with theirs.
What a fantastic piece of workmanship. Not to that Manic Mechanic doesn't produce fine work because they do and they work well for everyone for thousands of miles. It's just that Sportsman Flyer had taken it to a much higher engineering level in my mind.
First there are three parts to the adapter so you have the clamping load spread more evenly. The adapter is wider so there is more clamping surface and the bolts holding the sections together are heavier.
The towers that go through the spokes that the sprocket bolts to are longer so you have more reach. The hole in the sprocket is wider so the brake arm clears the sprocket better.
The 72 tooth sprocket and hub adapter cost me another $30 over what the standard set would have cost. I received the sprocket adapter and the sprocket for what just the sprocket would have cost me to have made to fit the Manic Mechanic adapter.
The adapter hub is over all more ruggedly built and the price difference between the two is less that $10 for the hub adapter and the standard sprocket sizes at the time I wrote this.
I am writing this simply because I'm impressed with what I received for my money and wanted to pass the information on. I feel if you purchase a Sportsman hub adapter and sprocket you will be equally please and happy with your purchase.
I have posted photos of both of the adapters on the tri car site. There are comments below the photos.
