Need advice/opinions - wrong size bike(5 posts)

Need advice/opinions - wrong size bikecking17
Apr 18, 2003 1:31 AM
To make a long story short:

After years of mountain biking, I bought my first road bike last year with the intent of racing CAT 4/5 - 58cm GT ZR 3.0 with 105 group. Turns out the dealer sold me the wrong size. GT's run big to begin with and on a standard road bike I should be on a 56 or 57 at most. Questions - should I:

A) Sell the GT take the sale money, add in another $1,000+ and buy an Ultegra level bike (?)

B) Buy a new frame (GT, Pinarello Galileo, Cervelo Prodigy, etc.) and have a new shop that I deal with tear down the components and build up the new frame?... which leads to two other questions:

1) What will a typical dealer charge for tearing down/building up the bike if I swap frames?

2) Is it a sin to put Shimano components on an Italian frame? If not are there any compatibility issues - I've heard the bottom bracket/drive train fit could be an problem.

Thanks in advance. Lesson learned: get a fit session with an experienced dealer before you buy.

Personally, I'd sell the whole bike and start over. Used 105 components are not worth a lot, but neither is a used bike. Expect 50% or less. While you're at it consider giving Campy Centaur a try. Costs about the same as Ultegra.

You could sell the frame only and have the new frame built with your components. The only item that would not be compatible with an Italian frame would be the bottom bracket. Most Italian frames have Italian threaded BBs. Other than that there is no difference.

I would expect a shop to charge about $150 to build up a new frame, but the charge would depend largely on where you bought the frame. The LBS might do it for free if you let them gouge you on the frame price.

your 58 is not really the 'wrong' size. Most 'experienced' shops size bikes WAYYY to small, IMO. What discomforts are you experienceing that makes you think the bike is too big?

Couplea questions to your questions:

1. If your problem is in sizing, why are you considering spending 1000 bucks on componetry? Ultegra provides a de minimus of benefit over 105. At a high cost.

2. Why pay a dealer at all to tear down/ build up? A free saturday is plenty of time to not only do it yourself, but also LEARN how to do it. Plus you'll be all the smarter and be less dependant on shops in the future.

You missed the obvious option; buy a used frame. There are plenty of barely-used frames out there from people in their never-ending search for their 'dream' bike. whatever that may be.

Thanks very much for the three posts. I have been scouting used frames for the past few weeks and only mentioned Ultegra since my budget finally allows me to move up to an "Ultegra level" bike. I wouldn't just swap 105 for Ultegra as I agree with you that it won't accomplish much except for a few grams here and there and a much lighter wallet.

I had a fit through a Serotta dealer - highly experienced in sizing. The stock 130 stem was swapped for a 100 but for proper fit the stem is "rising" which looks stupid and the stem police on this site would kill me (haha). After the fit, my upper back had far less strain on it while riding - none in fact. Top tube hits my crotch when I'm standing (shoes off). Bottom line is to keep costs in line I'll likely swap frames. Little kids prevent the Saturday build sessions. Haven't had a free Saturday in over 7 years... but that's a completely different discussion.

I would agree with Steve O, a 58 Cm. frame may be big for you but not unrideable, by any means. More racers end up with frames that are too small, rather than too big.

Check out the sizing info at the Rivendell website. A larger frame provides a roomier cockpit. You can stretch your upper body and move around on the bike better than on a smaller frame. If the saddle is three or four inches above the top tube, the frame isn't too big. You can always put a short stem on, if you feel the reach is too far. A year from now, you'll appreciate that a long reach enables you to rotate down to the drops without scooting back on the saddle, and ride with your back flat.

Alot of discomfort perceived as too much reach is really, as Rivendell says, too much handlebar DROP. A large frame puts the bars higher relative to the saddle. That's good.

So give it a chance. You may find this frame has advantages a smaller frame wouldn't have.
