Just wanting to show all the Mary bar enthusiasts what can happen when you are JRA. I'm posting this here because of all the rave reviews of the Mary bar and singlespeeding. I have been using the Mary bar much to my enjoyment on my single speed for about six months and transferred it over to my 1X9 because of an ankle sprain for the past few months and it failed by snapping off at the stem on a downhill section, I had just a second to tap the front brake and grabbed a tree limb to keep me from pitching over the edge of a nice singletrack. No scrapes, no pain except in the wallet since I'm going to a new downhill-type bar (31.8mm). Any suggestions for a strong bar? The stem was torqued to spec, so it probably was due to fatigue from pulling on it when climbing. Only 1,000 miles on it so I'm now suspicious with all the fancy tube bending. The bar is kind of flexy so this is the result. So if you're a big guy and kind of strong and riding with Mary, you better check it! I've got a Titec Jones bar on the SS now and its giving me the hee-be jee-bees now. Here's the link for the full story forums.mtbr.com/showthread.php?p=3970798

im still a believer of mary bar and obviously most of caucasians weigh more than asian does......... so i think there's a very huge difference in how they handle their bikes and in terms of their JRA (just riding along) is concern.....and of course our consumer rights (what consumer's rights?) hahaha

Wow .... anyone can tell that the biker holding the Mary bar is one Big Guy
I dont want to give the guy's story too much credit....for one: dont you think that he is too big for his bikeframe? pretty flimsy looking bike for the man
just doesnt add up
If you re that big ...use a hi-rise DH doublewall Hbar for 1x9ing os SSing IMHO

Awww. I was thinking of getting a mary myself. Well, I guess every part has a breaking point. I've even seen a thomson stem break on this very forum. I sort of remember reading an article long ago that handlebars should be changed every two seasons or so, since it is a highly stressed component. Cant remember where I read it. Maybe it was stressed indeed because of the weight and possibly aggressive use. Anyway, this is just a reminder to always use appropriate components for your riding, inspect your stuff before a ride, and always wear a helmet.

been following this thread on MTBR closely...
there are too many variables are involved here. One, some or all could have contributed to the part's failure. Could it be a manufacturing error on part of On-One? Maybe the way the stem's faceplate clamps on the bar gave it enough stress to reach its eventual breaking point? We'll never know, BUT(as coby said):
it's the rider's responsibility to check for wear and tear on his equipment. From handlebars to something as small as a crank bolt, we should give them a once over. Even Jeff Jones' titanium H-bars have had breakage reports.
I've been using the Mary for 2 years now, and so far so good. It's been on 3 different bikes too.
Thanks for the heads-up. All it takes is 5-minutes to give your bike a once over. As they say, an ounce of prevention...

wow i've never seen any Al bar break like that though. especially one that thick. shouldnt they bend first? looks like some sort of corrosion or metal fatigue.

if we can rely on what we can only see in the pic, both sides were white and fresh...suggesting it has no crack before it snapped...alum is pretty thick too in that area...the guy was prolly not telling the whole truth...maybe he crashed the darn thing.

in the MTBR thread the OP said that he noticed scuff and scratches where the stem faceplate had worn itself into the bar (like a saw or a file, I guess)...maybe slight manufacturing errors in either the bar or stem could have caused it...
and yes, according to On-One, the Mary is designed to bend before it breaks.

some facts: the guy calls himself a clydesdale, 220-230 lbs probably he used his mary bar on a full rigid bike. shows on the pic that it's not a suspension fork. SO... for people who weigh less than that, you're still safe using a mary. having front suspension helps in stressing your parts less (stem, handlebar, wheels, etc). fine fine, you probably noticed a defensive tone there. i like my marys. hehe

good points. But there is no published weight limit for these bars. There are a lot of 'cylde' riders who bought the Mary, and have no reported issues. Luck of the draw I guess. Best to inspect your bars (Mary's or otherwise! the rest of your bike too) before you ride, or whenever you wash your bike. some facts: the guy calls himself a clydesdale, 220-230 lbs probably he used his mary bar on a full rigid bike. shows on the pic that it's not a suspension fork.

Bossing, too bad for me... I am 6'2" and I weigh 230lbs... Maybe, in the near future, I will experience the same thing... mary bar is not intended for aggressive riding style.... meaning DH, Freeride or Dirtjumping are not allowed.... if you ride that hard then stick to riser for DH, FR or DJ specific hbars......

If you ride down like king kong you tend wear down or break your components faster. Coby and Agu already mentioned the importance of inspecting your stuff before/after rides. This will lower the chances of accidents. Malas nalang talaga if you get a lemon that wouldn't manifest cracks, dents or bending. I'll be closely watching the B&S section for a cheap mary bar. Hope I get first dibs. I weigh more than the MTBR guy and I would be glad test it on my full rigid ss. ;d

Well this is the first time I ve read that a mary bar broke ...so its doesnt seal the case for me ...I say use that Mary until she dumps you for another ;D I dont see how you can just break a Mary bar unless you re going fast on a downhill section and it hits a tree but hard (like a friend of mine a bonafide "tree hugger" ;D). Use the Mary brad Wow .... anyone can tell that the biker holding the Mary bar is one Big Guy I dont want to give the guy's story too much credit....for one: dont you think that he is too big for his bikeframe? pretty flimsy looking bike for the man just doesnt add up If you re that big ...use a hi-rise DH doublewall Hbar for 1x9ing os SSing IMHO Bossing, do you suggest for large bikers, we should use a high riser bar???

i think its a freak thing. havent heard of any other mary's breaking.
doesnt look like it broke at the bend so iwouldnt blame it at that.
