    I would second those opinions, definitely the best clamp in it's weight/price range.

    Good experience

    with the clamp.

    the headset is lousy to the point of being criminal.

    I assume you are talking about the old headset or the integrated one, because the new alloy standard one works great. Though the integrated ones don't work well on some bikes.

    Yeah, the older model

    that looked like it came out of a candy dispenser. I don't know about the new ones...

    I'm sticking with Cane Creek - not fancy but it works and works and works.

    It's arrived

    Looks quite flimsy, you can easily squeeze it together with your fingers and there's a small 3mm Ti bolt. But compared to my Ti bolt Salsa Liplock it saves around 21gms! It's been installed and ride for about 1.5 hours and it's held up fine.

    It's Broken!

    JRA and heard a creak and seatpost slipped down a bit. The M2 Racer seatpost collar has cracked so now it's back to the Salsa Liplock until I track down a lighter one. Any suggestions?

    21g saving over the salsa? Might I suggest one of Zoom's carbon-wrapped alloy ones? The 31.8 one is 21 grams total as memory serves (I was picking thru my clamps last week while building Orange Doom, and the Zoom one won over the Haro Clamp I have by beating the 23g with 21g).

    Thanks for the suggestions

    I'll check them out a bit further, other options I'm considering are, Hope bolt on and the Extralite seat collar.

    The M2 Racer cracked through right on the center point in the cut out section, looks like a spot where a stress riser can originate from. I wonder if my use of a Moots layback post has anything to do with it, as the post flexes it may cause more leverage on the seat tube/seat collar.

    Why am I NOT surprised...

    Go with Extralite and use the steel bolt. That, in my personal experience, is the best compromise between light weight and reliability.

    By the way, earlier this year, there was a thread started by someone on the Passion forum regarding the biggest bonehead purchase.

    My reply to that thread was my M2 Racer headset. It's basically the biggest pile of sh1t I've had the misfortune of using.

    And, sure enough, just a month or two later, I get emails from the company about how it's defective. It's obvious those crooks are just are just covering their tails from a legal standpoint.

    I emailed them and challenged them to examine my Sid World Cup; the carbon steerer tube had a groove from the p.o.s. headset. To date, no reply. Surprise, surprise.

    M2 Racer is the biggest sham in cycling components. If anyone from that company reads this: instant karma is a b1tch.

    I got off lightly...

    at least the seatpost clamp failure didn't damage my frame or seatpost bar a few very minor scrapes form it slipping a bit.

    How did you get on with the SID carbon steerer?

    I'll take up your suggestion on the Extralite collar.

    Not sure if I understand your question, but

    Basically, the headset wore a groove approximately 3mm wide and 1mm deep into the carbon steerer. I never would have known about it except the headset felt "rough" and the mechanic called me when he saw the damage.

    I'm certain the install was correct. The mechanic who installed it (different from the one who saw the damage) had M2 Racer on the phone and was give specific instructions on proper install.

    I pretty much got F#$cked. If I blame the shop, they'll point their fingers at M2Racer. M2Racer will, of course, blame the shop.

    I'm just grateful that the issue was spotted before the tube broke on me during some 30+ downhill.

    Of course, M2Racer never did respond to my emails about the issue.

    Most component makers wouldn't cover damage to other components anyways. Its not like M2 is alone in that. Rockshox isn't going to replace your wheel when their dropouts fail in mid ride for example.

    I did NOT expect

    them to replace the entire fork.

    I did expect them to come clean and admit that there are design flaws in their headset.

    I also expected them to reimburse the cost of the headset.

    Those are certainly reasonable expectations.

    I have been using thier raod clamp on a road bike for

    4 months and that bike get's bike time riding time and I have had NO problems.
    Are you also aware that thier Headset was recalled and they are still honoring warranty on them, even though they closed down? yes the desgin has a flaw and they addmited to this with their recall.

    I e-mailed them last week and I got a response.

    Maybe trying leaving a voice-mail and callig them. they returned my call within a day or so and they are still supplying dealers with left over items.

    M2Racer Recalls Bicycle Headsets for Fall Hazard

    JULY 17, 2006 --

    WASHINGTON, D.C. (BRAIN)—In cooperation with the CPSC, M2Racer of Burlingame, California, has voluntarily recalled about 150 M2Racer Conventional and Integrated Lite headsets. The headsets were sold at bicycle shops nationwide and through the M2Racer Web site from December 2004 through May 2006 for about $130.

    The headsets mount to bicycle frames and fasten to the front fork assembly. A protruding component of the headset can contact the steering tube of the front fork assembly, score or scratch the steering tube, and weaken the structural integrity of the front fork. The front fork could break, causing the handlebars to separate from the bicycle during use and result in a crash.

    M2Racer has contacted all headset retailers and received 21 reports of the headsets scoring the front fork assembly on consumers' bicycles. No fork failures or injuries have been reported.

    The Conventional headset is constructed of an anodized black alloy housing, stainless steel, and polymers. The Integrated Lite headset is constructed of a black polymer housing and light weight alloys. The Integrated headset weighs 29 grams; the Conventional headset weighs 39 grams.

    M2Racer will refund the purchase price of returned headsets. For additional information, contact M2Racer at (415) 738-8186 between 9 a.m. and 5 p.m. PT Monday through Friday, or by e-mail at headset@m2racer.com.</paragraph_body> </paragraph_body>

    Bummer

    about the damage to the carbon steerer, you're lucky the headset didn't seize up on you or the steerer break.

    If what Dirtboy has replied with, recall on the headsets, it'll interesting to see if they honor your headset.

    Did you use a torque wrench when installing the clamp?
