I was at the LBS last weekend and was introduced to "lock out" forks...at least I think that's what their called. What $400-$500 bikes come with lockout forks? The salesguy explained that I could "lockout" the fork and have it be like a rigid, in essence, for city riding or when I didn't need the suspension. Is this correct? I can get a 2008 Cannondale F6 for a good deal, but it doesn't have this type of fork I don't think. If the deal is really good(I think for like $300) should I just buy an aftermarket fork that does have this feature? Also looking at Giant Rincon, don't know if the 09's have this feature either. I've got a Marin now, but may swap out parts, or just sell it.
