'''96 Litespeed Catalyst, '05 Litespeed Firenze, '06 Litespeed Tuscany, '12 Surly Pacer, All are 3x8,9 or 10. It is hilly around here!
Do you have the tools to remove the old and install the new bottom bracket? I have no idea what spacer you have since Sora was a road group and the bottom bracket was intended for a 68 mm shell. Spacers typically come with cranks that can go on either 68 or 73 mm shell widths.
