The time has come again to make another series of PROMAX PD Fork Valves.
http://store.suspensionshop.org/maico/mx/1970-1979/79-79-mc-250-pd-fork-valve.html That is also the time to tweak the drawings and make improvements, if needed. There are many out there globally and doing a good job already. I would welcome any CONSTRUCTIVE criticism or hints for improvements and changes from you, now, before the machining is done. The areas that can be changed (if needed), are:
• Ports
• Lift plate free bleed
• Size in OD of main body
• C of spring (at the moment we use 7N/mm and 12N /mm )
• Materials used
Thank you
