Merckx AX or EX, major differences?jeff27

Anybody have any experience with the Merckx titainium AX and EX frames?
I was wondering what the differences were. Saw a late 90's (98 or 99)
ti Merckx AX frame for sale. Was considering it.

Thanks in advance for any info.

You might want to do a search on this topic at the Velonews forum, this question came up and there was some conflicting information.

I rode a EX for several years looked at the AX back when I bought mine - 1996 or so. The EX had ovalized and tapered sections on almost all of the tubes as well as massive chainstays. The early AX's had less shaping of the tubes and smaller chainstays. Some people on Velonews reported that the AX gained some more tube shaping later on but I can't confirm this claim.

Overall, my understanding is that the AX is similar to the current Majestic excepting some braze-ons differences and head tubes are different - Majestic is oversize now although I don't think it was always this way.

Nice frames either way. Built by Litespeed by the way.

Check the following link to some EX photos.

The AX you saw is probably the one I'm advertising on RBM. The EX is definitely the stiffer of the two, if that's a priority for you. The earlier AX frames were reported to have some problems with high speed shimmy, so in '97 or so they changed the tubing to stiffen the frame and I never saw any similar reports on the later frames. I certainly haven't had any shimmy with my '98 and I regularly descend in the mid-40 mph range and occasionally faster. I'm about a 165 pound non-sprinter and ultra-stiff frames have never been a priority for me. I don't get any derailure rub on the AX, but a more powerful rider might.

As Ed said, the later AX frames were basically identical to the Majestic except for the head tube (the '98 is 1" threaded - I believe they went to 1 1/8 threadless with the Majestic).

Hope this helps,

yes, it is.jeff27

Yup, that's the one. You advertised a little while ago (couple of months, i think?)
We exchanged emails about it, and you had decided to hold on to it for a while.
I'm interested, but unfortunately this isn't the best time for me, goldarn it!! Timing
is everything. Ahh well, good luck with it, hope you find a lucky buyer.

I've been pretty back and forth with that bike. Every time I decide to sell it, I ride it a few times, like it, and then I firm up in my negotiations and blow whatever reasonable deal is out there. But I just don't ride it enough to keep it (I have a semi-custom steel frame that's a bit heavier, but the ride with my own personal 165 pound configuration on it is just crazy perfect).

So if I get an even half decent offer, I'm gonna part with it this time. But it's gonna hurt.
