I checked out the LBS and have found: Park PCS-1 $145 US Ultimate BRS 70 $125 US Wrench Force $125 US
My observations: Park - no vertical adjustment Ultimate - much vertical but/and has tripod stand Wrench Force - some vertical not tripod (cross between park/ultimate)
Regardless... With my Giant TCR2, I will always have to take the seat off and install a dummy seat post to do any maintenance. Most people including Giant say to hang by frame or carbon fiber seat post is not recommended.
I normaly just use my indoor trainer. It's not the best option but it's all I have.
With my older bike I used to hang it from a tree with a rope around the saddle. It's not very stable but allows you to work all around the bike and you can bring the bike to whatever height you want.
Being handy with a welder I built my own car cycle carrier. I also made a stand where the carrier fits in. It is at just the right height. I even service my tandem on this carrier/stand. The tandem sleeps permanently on this stand. Without tigthning the clamps I can do anything on it. I have removed the cranks, BB, service chains etc etc. I even wash my bikes on this stand. Works very well and is cheap. It might not have the versatality of a Park stand to swivel the bike but the bike is at eye level and you can work on the bike.
I just purchased the Wrench Force stand...and, for the price of 150 at my LBS, find it to be very solid and well made. I don't think you'd be at all dissappointed. I was impressed right out of the box, and have put it to use on one of my three bikes almost daily. <br />I too install a spare seatpost to clamp on, and would never let the stand bite any part of the frame. Too much possibility of crushing the thin-wall tubing or damaging the finish.
