Front sprocket question

[Chris.L]

Since I bought my 2017Cube race with Bosch's crank drive I have lost weight ,I have dropped from 135.5kg to 94kg ( indoor bike,weights, rowing ,walking and on the ELYFB diet have all helped) I now max out my speed on the cube and wondered if a change of sprocket would give me a speed increase
Cheers

FSA CK-745, 15T ?

At 9.90€ a pop you could try a couple up to 20T to see which suits you.

18t will give you about 35mph with 120rpm at the cranks and 20t will give about 40mph at the same rpm if the bike is unlimited.

maximum effort is required tho so avg speed will differ depending how fit you are.

Thanks all , I have ordered an 18t to give a try , is there a specific tool I need to remove the sprocket
