Because of the era of production, the length of the bike is actually fine, and it's just the hight that is off. Where is the problem then? Saddle too high even when lowered as far as possible? The wheel size is completly irrelevant for that problem. Or are you unable to stand on the ground without your privates hitting the top tube?

Actually knowing if a bike frame is the correct size based on height is nearly impossible, they are best guesses. When looking at fitting a bike there are so many different things a fitter will look at. First lets look at what changes on the bicycle when you change frame size:- Top Tube (TT) - this is normally measured as a theoretical as this tube is not ...

At that weight it is 99% Aluminum. This is also backed up by the sizing of the tubes, as Aluminum has a much lower density. At the sizing and thickness of the tubing for it to be Ti/Steel it would be a considerable amount heavier. The uniformity and consistency of the yellow/bronze would lead me to think that this is most likely anodized.

Hard to tell anything from the photo but it's definitely a low level frame, most likely from the late 1970s. The giveaways are: The thickness of the lugs. Good quality lugs (such as Nervex or Henry James) are much thinner. A top level builder will thin the lugs even further. Those are cheap stamped lugs. The square ends of the bottom bracket lugs. Crimped ...

Falling off the bicycle would be far more dangerous when the frame is too large. Especially if you ride on ice, cross-country, or use clipless pedals. You posture also should be grossly wrong given the stated size difference.

The most important measurement is top tube length or how „stretched“ your position is. One can try to compensate with stem length. (I dont have any problems with reaching ground with my feet when I stop) That’s not necessary and actually often a sign for a too low saddle. Saddle height is usually not limited by frame size, unless you have very short or ...

That frame really is considerably too large. If at all possible the best bet would be to ask to exchange for a smaller size. Many companies now offer 30 day return policies for bikes that have not been used beyond a short test ride. In terms of fitting problems, the most likely areas to be effected will be the lower back, shoulders, neck, triceps and ...

I did a similar conversion of a woman's road bike (1975 Peugeot UE18) to a commuter. The main changes were switching out the handlebars from drop bars to porteur style bars, the inclusion of a dynohub, and the addition of a two-legged kickstand for stability. My Peugeot already had a nice saddle but in your case I'd add a good Brook's saddle since your ...

That's a nice looking bike, it seems like it would be a great start for your project. The big question is whether or not the bike fits you – if it does it will be worth considering what else you could do to make the bike into a dependable commuter / day touring bike. Start by trying to get the saddle and handlebars into a position where you are comfortable ...

That's the mount for the Flow Control valve on the Specialized AFR Shock. The shocks with flow valves came stock on the higher end models of the 2007 Stumpjumper FSR like the Expert, Pro and the S-Works Carbon frame:

So I asked the same question on the chemistry forums. They came up with interesting answers. For those who are curious: http://chemistry.stackexchange.com/questions/32831/how-to-detect-lead-paint-on-a-bicycle Btw, I've tried scratching a bit of paint off the frame. It works just fine without chemical stripper. Won't take more than a few hours!

Rough up the paint with sandpaper, and then use Aircraft Remover to get the paint off, if you try to sand it, you'll go crazy. DO NOT use aircraft remover inside, and wear a filter mask, it will make you sick if you don't. It will rip the paint right off. http://www.rustoleum.com/product-catalog/consumer-brands/auto/paint-chemicals/aircraft-remover

No. Generally, you need to know the manufacturer at least and then see if theres some code for their serial numbers.
