    big dude and a road bike (vs 29er on the road)

    so i'm a 300# guy... a MTBer at heart... but with the family and job i can't make it out to the trail as much as I'd like... i've started to spend a lot more time on the road as I can do a 20 mile loop in the time it would take me to get to and from the trail (not including the time to ride)

    I'm starting to enjoy the road miles more and more... did a 62 mile ride for the tour de cure last week, planning to do a full century ride come october when they have another fund raiser ride.

    I've got a 2nd 29er that i've setup more for the road/commuting duties...i've tossed some slick centered cx tires on my rigid 29er (700x40 kenda kross up front and 700x32 specalized borough cx out back)... set it up with a little narrower cassette (11-28) and a titec H bar for the extra hand positions (it was GREAT for me on that 62mile ride)...

    now i've got a dalema (SP?)... my bike as it sits is about 30#... it is after all a MTB... the weight would come down a bit with some true road tires (thinking 25 or 28's) and that requires different rims... replace the discs with canti's but even that wouldn't be much in the way of weight...

    so i'm thinking about the possibility of a road bike... i'm not realy comfortable with drop bars so i'm considering building up a road bike with the titec H bars... (would also save a bit of money as I wouldn't need to use STI controls)...

    the other option I'm considering is an inexpensive CX frame... overall either would be a good bit lighter weight.

    so the real question... would I be noticeably faster on a flat bar road bike over a similarly setup but heavy MTB?

    i'm keeping my eyes out for an older road bike but thanks to the fixie craze they go quickly

    Go for a drop bar road bike, they are not nearly as intimidating as I thought they would be. I got my CAAD9 when I was your size. I love it, and could imagine riding anything but a drop bar roadie.

    Road bikes are for The Road.
    I would try to take weight off of the motor before making the bike lighter.

    Does the 29er have a suspension fork? Does this fork lock?

    I would also get a regular road bike. Models that they call "plush" these days have higher stem/handlebars and longer wheel bases than pure race machines. They ride much smoother than race bikes, and you won't be all folded in half when you ride.

    All bicycle companies make them these days. Popular ones include Specialized Robaix and Sequoia, Giant OCR series, Trek Navigator and 7300, Jamis Eclipse and Quest and Satelite, etc. I have a friend that really likes his plush Windsor bike from Bikes Direct, and it was really inexpensive as well.

    If I were looking for a comfort road bike, I would also get one with rear rack mounts and with 26 or more spokes on the rear tire.

    Good luck!

    If you put 28's on your Redline it would be the same as riding a flat bar road bike. If you want a new bike, get a road bike with drop bars. The weight of the bike doesn't really matter.

    I'm 290ish and I went from a heavy hybrid with suspension front end to a heavyish cross bike. difference in speed is very obvious. I built up a Surly Cross Check with Campy parts (mirage/veloce mix)

    do not be intimidated by drops - most of my time is riding on the hoods - love it.

    Have you looked at a Kona Jake? Good entry level CX bike

    Don't let the drops intimidate you. The biggest differences are in the wheels and the positioning. Road bikes tackle both of these and give significant gains. Light'ish 700c wheels with some 25mm tires and a decent fit to a road/fitness/endurance-fit frame and you'll be laughing.

    300 lbs person, 30 lb bike. Bike is 9% of rolling weight. 25 lb bike...bike is 7.7% of rolling weight. Changing bike types to a road bike will probably result in better speeds due to decreased wheel weight (easier acceleration), better aerodynamics (on hoods vs. flat bars), and skinnier higher pressure slick tires (decreased rolling resistance). The slight decrease in weight is unlikely to make a noticeable difference unless you spend a tremendous amount of time climbing hills.

    My recumbent bike when outfitted for commuting with a day's worth of clothing supplies, tools, fenders, large bag, and lights tips the scales at 50 lbs.

    I suppose it was a mix of if it's more the aero from the seating position or the bike itself or the low rolling resistance of the skinny tires that make for the biggest differences...

    this is what I have for my current "road" bike


    an older trek popped up on CL... going to look at it after work if it's still there...

    Drop bars only work if your gonna get in the drops. Seriously, look at all the people you see out riding, how many use the drops.

    H-Bars or Moustache Bars are the way to go.

    I did a 100k on a mtb, that gets old quick. On a road bike 100k rides are routine.

    ... went and bought an older road bike... '92 trek 400 to be specific... last of the lugged steel frames... parts aren't anything to write home about but it's a nice bike for the price... I test fit my 700x32 cx tires on it and they fit fine (although getting them though the stoppers isn't so easy... so must go in/come off flat so thats good to know

    need to tweak the fit a bit more... but sure feels fast and seems like the frame size is spot on... will upgrade with more modern parts with time... not a huge fan of down tube shifters, so i'll have to decide between STI or bar end shifters... but for now i'll get a good fit on it and log a bunch of miles on her.

    BTW you and your friends in the pic have great taste in bikes. I love the Titus and the Salsa, and looked into buying a Redline 29er(single speed) for myself. I really do love the Titus, and there MTB's are bad ass.

    Easier to say, than is to do for many.

    Slowly I have been dropping, was almost 300# two years ago, now 265#, and following a more natural diet that includes; grains, plenty of water, avoiding processed foods and meats, and cutting back on diary, no fat only. Actually feel sick if I do eat a burger or a taste of fried foods.

    Road bike with drops is the way to go, finding a sturdy frame and well built wheels and quality tires will provide you a more relaxed and enjoyable experience.

    I rode a century last summer on my hybrid, upright position, and it was fine with the wind at my back and on the flats, but hills, and head winds made it very tough, even when I positioned myself lower using elbows on the grips. Kept telling myself brought the wrong bike.

    I was not happy with my time that day, so I returned a month later with my trusty Schwinn Continental (26" frame, with alloy rims, bike weight 34#s). Same hills, almost same wind, just 10 degrees warmer.

    The total experience was much easier, drops were great for better leverage on climbs, and a very slow incline into the wind. Plus the 52 tooth front sprocket provided better rhythm on the flats.

    Rebuilding a Super Sport presently and hope to have it good to go for the same event this July, or a same size Superior if I convert to bar end shifters by then. (Both 26" frames.)

    I have all three of these road bikes set in a touring fashion, with the top of the drops even with my saddle top. I also have a lighter bike (24#) with the bars set lower, but it does not feel stable underneath me if a strong cross wind is present. It does climb hills nicely.

    This is my effort to save steel from FG conversions, as I just added a LeTour to the stable a couple weeks ago, because I loved the condition of the 25" frame and its Sky Blue paint.

    Have fun and enjoy the Trek, hopefully you can dial it in for comfort as well as performance.

    You are doing good.

    with my weird praportions (long in the legs and short for my height torso) and lack of flexability I think the trek is about as close to the right size frame as I could hope for... stand over height is near non existant however the short seat post is nearly maxed out... I think when I bring my bars up a bit more the fit will be just about dialed in... need to swap to a decent saddle... going to use my WTB for now but I think a brooks is in it's future... I think it'll be a good bike for me... and if I end up not getting it to where I want it's easily swapped to a fixie which will make it easy to sell for at least what i've got into it

    I'm just shy of 300# and have been riding one of these since last fall/late summer.


    VERY happy with it.

    As a matter of fact, I'm waiting for my wife to get her gear on and we're heading out for about 15 miles.
