    Heavy Rider Frame

    I have a friend who is 250 Lbs. I am a bit concerned because he's riding an aluminum canondale centurion, (one of the first ones, uh-oh).

    Right now I have no idea if that bike is okay for him. He rides in the city where it's pretty rough, potholed. So far his bottom brackets look okay. He also has a 1992 Bianchi Eros. All these bikes are 23".

    I've been looking at tubing spec. charts a lot lately. Most tubing seems to max at 200 lbs. rider weight.

    I am curious, would an old beater like a Raleigh Record (see my thread on that) or a Scwhinn varsity actually be the way to go? I'm thinking many of these carbon tank-bikes were built this way to deal with this newbie bike-boom issue.

    I have no clue about what's a good heavy-duty frame in a modern road bike, as all I've been seeing is carbon and aluminum. If anyone can post a pic or recomendation, that would be great. He might shell out 4-500 bucks for something decent.

    The Bianchi was sold to him by a bike shop, so it might be OK, but the Canny was a garage find.
    Thanks!

    We have a whole forum for the hefty rider here where they would probably happily answer the retail resurection side of this question. From a frambuilding perspective, for city riding, there isn't that much that needs to be done to create a heftoid frame. Mostly the triangle is strong enough regardless. If the rider is stronger and agressive in proportion to their weight, that is when stuff needs adjusting, assuming they are pouring it on. A heavy rider is not the test an agressive and dynamic rider is. Fat heavies don't always want to get the jiggle going, or agravate the sometimes painful joints or backs, and they may well not even minimally load the bike.

    Thanks, can you give me the title/headline/tag for this group? I can't find it, is it the "50 Plus"?
    I think I'd have to ask the moderator to move the thread for me, no?

    This rider can be a bit aggressive in his style, and he is extremely strong. but I'd like to hear more for sure.

    It would be the Clydesdale/Athena thread. The wife and I fall into those groups. Her Miyata MTB has normal tubing and has lasted for many years under her 250 + weight. My Bruce Gordon has tandem grade tubing and could probably hold 400-500 pounds. We have steel frames.
