Get yourself a 16 front sprocket , 1 tooth on the front is almost like 3 on the back . I used to run 16/38 at a track that is similar to PI , for me it was 1.8km straight - 2 straights with a flat out corner . A few NSR's would clock 238km/h on the gps .

Care for a friendly challenge for next year ?
