We have had a lot of requests for a group buy on these and with the blessing of Supersprint Italy here it is.
I am sure these need no introduction but here is some information to refresh your memory.
These are the step design headers from Supersprint that provide the highest gains from the Supersprint range. They require the Supersprint section 1 (cat or decat) or a custom section to fit.
