dont do it! nobody makes a 20mm sprocket! i found it impossible to find a 25T

24/7 sprockets were 20mm.Trouble is with some 20mm spindle cranks is that not all of them taper to 19mm at the ends...ie older D20s

My son is running one of those conversion kits, And he is using a 24t Profile sprocket.
Bearing number is 6004, Just do a search on ebay.

A 6004 bearing is a virtually generic MX and trials wheel bearing - should be very cheap anywhere, but avoid buying chinese bearings. British or Jap for decent quality.

I've got some mid 90's fishbone 20mm cranks that, luckily are 19mm on the splines so no problems with sprockets.

the d20 bottom bracket from custom riders is tapered to fit 19mm sprockets as i fited one from them to my neices bike a couple of months ago :daumenhoch:
