Question on adjusting a suspension fork (suspension n00b)
My wife bought an '09 Globe Carmel 3 with a suspension fork and doesn't seem to be able to get it really stiffened up enough. I know essentially nothing about sproingy components, but she says the dealer's advice was that it should be adjusted so that it does not compress under the rider's weight but does compress when she hits bumps, and that the preload is adjusted by a knob on the right fork tine. Okay, makes decent sense so far. Except that the adjustment knob on the right-hand fork tine has been turned many full turns to the right and is now clicking every revolution as though it's at the end of an adjustment screw, and the fork still squats when she gets on. There does not appear to be any sort of adjustment on the left-hand fork tine, though if there were I imagine it would be for damping and not spring preload.
This particular fork is labeled SR Suntour NEX-4100, for what that's worth. I downloaded a couple of PDFs from the Suntour website, but the only relevant info I've found is that the right fork tine has the spring in it, and we already knew that.
Does it sound like we're doing something wrong? Do forks for "comfort" applications such as this bike sometimes have insufficient spring rates to provide the recommended performance characteristics? Or is there possibly some sort of adjustment procedure that we may be overlooking? The Specialized owner's manual is no help at all, as doesn't seem to even cover specific model ranges. I suppose (based on wild assumption) that it may be theoretically possible to disassemble the fork and substitute a higher-rate spring, but it seems silly to think that such a measure would be necessary.
