Came across this cool gearing calculator… and it includes Raptors!!!! I couldn't find any previous mention of this site here. Apologies if it is old news.

(The reason for coming across it will become apparent with my next posting Hint: I'm thinking of upping the front sprocket to 17T.)

Re: Speed, RPM, chain and sprockets calculator
Err… well, I did buy the sprocket but still haven't fitted it (I just tell myself that I'm saving it for a special occasion ). My personal view is that the lowest gears are pretty low and one extra tooth may be interesting, given the flat torque curve of the 1000 above 3000rpm. If I ever get around to fitting it I'll comment further.

The raptor will pull it now worries for sure. I thought the stock gearing was quote good but I went a 15 on the front because I like wheelstands
