    Is this true about 29ers?

    Quote Originally Posted by cyccommute View Post

Giant has recalled some and Trek is reported to be having lots of warranty claims on them. It seems they pushed the idea before they had worked out the kinks.

    The other reason not to use a 29 with front suspension is that the 700C wheel has more side deflection than a 26" wheel. This allows the front suspension legs to work independently which isn't good with the kinds of forks we use now. Add a load over the front wheel and the fork could get real noodly. You can solve the problem by going to a 15mm or 20mm through axle but that's a bit extreme for a 'touring' bike.

    The 26" wheels use hubs that have been optimized for 26" forks so they tend to be more solid and less noodly.
    Would you still get a 29er with front suspension?

    Thats weird - when cyccocmmute makes the occasional foray into the mtb forum he typically gives solid advice.

    The quoted post, however, is faulty reasoning supported by utter nonsense.

    I just read the Giant recall in Bicycle Retailer and it was from Nov. of 2010 about 2011 model Anthem X 1,2 & 3s. Frame crack at the junction of the seat tube and top tube. That could happen with any production run of any size - - had nothing to do with 29ers specifically.

    It's all about perception with Cyccocomute. He once stated you needed more light to ride in town at night than in the woods. His reasoning was that you have to compete with the ambient light from street lights signs and auto lights. If that's true you would need to be brighter than the sun to ride streets in the day time.

    This is the only part of that whole thing that I would say is true. It is also common sense and can be solved with proper engineering. The reason they flex more is because they are longer. Torque is equal to force X distance, meaning that a taller rim will have a larger torque on it (while turning b/c the force has to be perpendicular to the thing it is acting on) however, this can be fixed by designing the rim, spokes, and hubs to work together to handle these forces (which is what the engineers get payed to do). As for the fork legs working independently due to this......... There are forks that one leg is just for dampening, and the other is for the spring, if this was the case, these fork systems wouldn't work even on a 26" wheel.

    So you hate the engineers that design the bikes that you ride? Because that is my future goal, to be an engineer for a bike company such as Trek or SRAM and I only have 1 year left before I graduate with my BA in Mechanical Engineering which is the first step to meeting that goal.

    Yes, I hate you. (I forgot to put this at the end of my statement: ) I was kidding. Congrats on your goal BTW...now design me a freeride 650b with about 7" travel, 67' HA, 24.5" ETT, and 16.5" stays.

    It wouldn't even work with a 20" wheel.

    Aside from manufacturing defects which do happen, the only way a frame is going to break is from a hard crash or using the bike in a way it was not intended to be used.

    The one with the Giant has been addressed, and knowing that the treks are failing at the chainstays because the original inner sleeves on the superfly's were carbon and were not holding together as well as an aluminum sleeve would. The 2012 superfly's have the aluminum sleeves in instead of the carbon.

    Get me a job for any good bike company such as Trek, Giant, Specialized, or any of the smaller ones like Raleigh, Kona, or Jamis, and I'll do my best .

    I learn something new pretty much everyday here on the forums and feel that I already have a pretty good understanding of bikes, but I still have a long way to go before I know enough to feel that I can design a bike from the ground up (which is one of my other eventual goals "I have lots of goal")

    Go with Jamis, they seem to be pushing the 650b (or maybe that's just Ed brainwashing me again with his "New for 2012" thread...)

    Only issue is location. The only bike company I've looked into (until now) for employment was Shimano, and their only US location is in LA and they do not do any engineering there. I just looked into Jamis and their only current open positions are in England. I would like to stay in the US. I'm open to moving, me and my fianc้ both plan on moving as soon as we graduate, so that is not an issue. But finding an american company who would keep us in the US is a big deal. BTW, she is also going into mechanical engineering :lol.

    Sad part is I still have a year to a year and a half before I graduate. Also, most of these jobs require 3-5 years experience in the engineering field, but this is what I would like to be doing eventually. I've known for a while that it will take me around 5-10 years of experience before I can pretty much choose my job, so I've known that this will be a long term goal. However, thank you for the link, and giving me another company to consider when I do graduate. Thanks for all the support. Like I said, I still have a long way to go, but I feel that if I continue trying, I'll get there eventually.

    I'd take a job there. I ride what I ride b/c it's what I can afford. When I recommend something from them, it's either b/c I know it works ('05+ Komodo /'10+ Parker) or I'm intrigued by the idea (650b).

    Another thought: You might pursue an engineering internship in the cycling industry - - it may help get your foot in the door as well as getting you credits toward your degree. Kyle Thomas, a young friend of mine (and Pro downhill racer) interned at Transition Bicycles for a term. He's now working in the aerospace industry in Seattle instead; but had he chosen to stay in the cycling industry, I'm sure it would have given him a leg up.

    That would be awesome. I am planning on just letting the cards fall. Obviously in the current economy, the first decent job offered to me is what I am going to take. I already have a years experience working as an intern for a company who designs electric motors, so I have a foot in the door there and if worse comes to worse I'll go there until I get enough experience for somewhere else. Working for transition sounds like it would be awesome. It would be amazing to be able to be the person that gets to test the new bike designs.
