Smaller front sprocket

The sprocket change has to do with the winter tire project. I`m not looking for any performance gains, only some more room for the rear tire. The problem is the gap between the swing and the tire. With the first tire (120/90-18) there was zero clearance with the mud guard attached.

The second rear tire (110/100-18) was almost good to go with no mods, but I wanted to make sure I got enough clearance so I spent the extra 12€ for a smaller sprocket.

The job itself is very easy. You need some slack for the chain, which requires loosening the rear wheel, but thats quicly done.

Original on the right and the new 13 tooth on the leftThe size difference is not that great

The gap should be enough now

  1. I’ve thought alot about this ‘mod’. I know you didn’t do it for performance gains, but how is it? I assume your top end is compromised abit. How is the acceleration gain?

    I know It puts the speedo further out…

  2. Arh I see, spikes, cool!

    No it appears to take the speedo feed off the crank as changing sprockets defo affects it. You can buy a device to correct it though…
