Hi Folks
Been reading about the use of biopace chainwheels on recumbent bikes and it would appear the power cycle points are not the same for a bent as an upright , anyone any more ideas on this or do I have a play and see
mine has 5 bolt holes and if I remove the crank ident pin I could move the timing by 72 degree increments ( 360/5 = 72 ) reversing the chainring would allow 36 degrees with a bit of a mod .

any thoughts

regards emma
