Welcome to the new and improved Proflex / K2 Tech Forum!
Steerer tube sizes for Girvin AL fork with 1" steererSteer Tube Standard for bikes with head Tube 90-125mm is listed as 222mm part number 15003-5Steer Tube Long for bikes with head Tube 125-160mm is listed as 259mm part number 15003-6there is no size listed for the fork legs but they did come in two sizes.These forks were available aftermarket and were sold as a Girvin Linkage Fork.There is no listing for a 1 1/8" Long steerer either, only the standard ones, these are actually 1" steerer tubes its only the crown race seat that's 1 1/8" so a headset shim is still req.http://www.k2bikes.com/PDF/techLibrary/1997/vector2_assy.pdf
show us some pictures if you do manage to make one
One thing to note about the earlier Girvin forks...though they had a mostly 1" steerer, the bottom of the steerer had a step-up ridge, and these forks still used a 1 1/8" headset (you had to use an adapter to make the top part of the 1 1/8" headset work with the 1" section of the steerer). At least that's the way it is on my 856s. Is anyone out there running a 1" headset with a Girvin fork?That said, it seems logical that one might be able to machine off the step-up on the bottom of the steerer, so it truly used a 1" headset.Thoughts?- Doug :-)
