Billy's modification (essentially a larger-diameter pipe that accepts the one on the stand), allows the stand to be raised and lowered, which is a nice feature that lets you put bikes in the best position to work on them regardless of type, or where you clamp. This week I made another modification: I switched out the old clamp for Park's relatively new one, the 100-3D (+/- $130). Watch for a full review in Jim's Tech Talk, my weekly column in RoadBikeRider's free e-newsletter.

But even more impressive is that the clamp jaws open to a gaping 3 inches wide (76mm) and can clamp right down to 7/8 inch (23mm). That's the main reason I got the new clamp: so that I can finally put my Cervelos' with their aero seatposts in my repair stand (the old model opened to 1 3/8 inches).
The clamp also has a combination screw/quick-release action that lets you carefully fine-tune clamp pressure so you won't damage whatever you're clamping. And see that blue part? That's rubber so you can rest your delicate carbon seat rails on there if you're doing some quick job and don't need to clamp the bike. A nice detail to protect your equipment.
Now the only problem is not getting emotional about retiring the still-going-strong original clamp, which has been so reliable all these years. I think I'll give it a place of honor on my workshop wall and switch out the clamps when I'm working on something deserving.
If you've got an older Park repair stand or are purchasing a new one, you may want to consider getting this clamp.
