Question about quality bike fit...(13 posts)

Question about quality bike fit...Triphop
Feb 14, 2003 10:39 AM
When getting fitted, is it necessary to be fit on one of the Serotta fit bikes? Or can you get just as good of a fit without one?

Opinions?

If the fitter knows what he's doing, any bike that's close to your proper size, with known geometry, can be used for a fitting. With open-face stems, it's a five minute job to change a stem. Any problem with the seat tube angle will immediately show up if the saddle is way off center on the seatpost with the knee positioned over the pedal spindle (the starting point) or you preferred KOP position (if you know it). Each degree of STA equals about 1.2cm of saddle movement.

The Serrotta fit bike allows the fitter to adjust the seat tube angle and top tube length, which is great if you have the option of a custom.

To get a truly custom fitting, you need to use the same type of saddle, seatpost, pedals and shoes for the fitting that will be on the finished bike. Changing the style of seatpost and saddle can make a big difference in the STA needed to center the saddle on the post.

C-40...Thanks for the reply. One more question, is it bad form to pay for a fitting at a shop to find out your needs, then go shop around and most likely buy from another source, beit a shop or a private seller?

I'd shop around first. If you find something you like, see if the shop can provide you with a fitting for free if you buy.

If you pay a significant amount ($50-75) for a fitting, then that's what you're paying for. You should be under no obligation to buy. If you're a beginner, the fitting will be nothing more than a starting point. It can take a year or two to fine tune your optimum fit.

Read up on fit procedures at www.cyfacusa.com.

If a fit bike or real bike is used, just a rudimentary check of inseam or standover clearance is all that's required to get started. Just don't forget the importance of the saddle, seatpost, pedals and shoes in the fitting.

I am asking for a friend, she is wanting to get a road bike, and one of the better shops, which is where I think she should get fitted, really only sells high end stuff, i.e. - out of her price range.

So, would you suggest her best strategy is to just use a standard inseam fit formula, such as wrench science, to get an idea of what frame size she should look at. Then find a bike that fits in her price range (new or used), then go get the fit on the bike she purchased?

I was on the Spectrum website and saw something that made a lot of sense. When you go for your fitting tell the fitter what handelbars you will be using and the reach and drop. I changed my bars and ended up needing a 1 centimeter longer stem. WWW. Mud Sweat and Gears has the measurement of many popular handelbars. They vary greatly with regard to reach and drop.

There's another thing that often is not addressed during a "custom" fitting. Without all the components that you intend to use, the custom fitting could be off by 1cm or more.

You can get some formulas off the internet, measure yourself, and figure it out theoretically. But actually getting on a fully adjustable stationary bike and feeling the measurements tells you more.

A great Serotta fit bike is nothing without an intelligent person to set it up and interpret it. I'd look for a fit tech. you trust, even more than the machine.

It comes down to the skill/ experience of the person doing the fit. Typically, a Serotta size cycle is proof that a shop (not necessary the person doing the fitting) takes proper fit seriously . However, it is not a gaurantee of a good fit(and only serotta dealers have access to the serotta fitting method. There are a ton of great shops who are not Serotta dealers). Many companies can build you a completely custom frame with only a few measurements off your old bike and your person.
Tell your friend to first find a shop where she is comfortable with the staff (experience levels, perosnality,service, etc) who will work with her needs. Typically, when buying a good entry level road bike, all the accessories, etc etc, you're going to end up spending about a $1000. If she's going to be spending that type of moeny this time of the year, I know a ton of shops that would be more than glad to fit the bike for her and help her get started on the right foot.
