Im looking at getting a good deal on an older E Merckx TSX frame to set up as a winter-beater/fixed-gear ride. I've heard from some that these tubes give a harsh ride (for steel) and from others that you end up with a smooth ride (esp for bigger frames like 60cm). Any comments?

I think they might just be a tad stiffer laterally through the bb than some of the lighter ones like my Reynolds Merckx (which I also use as a winter bike). I think in terms of "ride quality" they're about the same--it's mostly about the geometry and how it fits/works for you. Merckx bikes have slightly longer c-stays, slacker STAs and lower bbs than most bikes. Regarding the supposedly "harsh" ride of certain tubesets--I personally don't believe in this who "verticle compliance" thing. Check out what Sheldon says under "verticle stiffness" below.

One's a custom Marinoni and the other's a Pinarello Gavia. For reference I also have bikes made from Columbus both SL and custom drawn nivachrome, Reynolds 531, Ishiwata, and Deda SAT 14.5.

A lot of the ride is dependent upon the frame builder and the frame size/specifications. That being said, in my smaller size 50-51 ctc, the TSX is my least favorite tubeset due to its weight and harsh ride. I would guess that in larger sizes, these factors are not a factor. TSX didn't have a long market life as it was quickly supplanted by EL/OS which was lighter, as stiff but allegedly gave a more compliant ride. Keep in mind that Andy Hampsten won the alp d'Huez stage on a TSX Merckx.

For a winter beater bike, it would be fine. The TSX Merckx's used the 'Century' geometry which gives you the lower bb, relaxed seat angle and longer top tube. The SL and SP models of that era from Merckx had more of a criterium geometry.

Good luck.

I know it's been said on this forum before, but I'll throw it in here again: wheels make a huge difference in perceived "ride quality." Rim stiffness, number and gauge of spokes, tire type, size and pressure all have a huge effect on what the rider feels. There really is no such thing as a categorical "TSX ride."

Actually, wheels have little, if any, vertical compliance.

Tires, like you say, make a huge difference.

I had one of these years ago. It was a nice bike. TSX was basically beefed up SLX. It was a frame designed for bigger riders. It is heavy by today's standards, but a good bike. It would be a great fixed gear bike. I can't remember if the drop-outs are horizontal on it. Are they?

As far as harsh ride, its not true.
