Still have three 650c wheeled bikes and raced back in the day on spinergy wheels. Good wheelset but plagued with issues early on, seeing that they are the wrong size I would sell them. You'll get your money back if not a tad extra because there are still people out there looking for them (650c) because I sold an old set about a year ago for more than that. Just post in the right spots and you'll recoup your money, good luck with whatever you do.

For what its worth I'm going to put the spinergies on a bike for me (6'2.) I also have a 47 frame bike which I'm probably going to fix and give to one of the girls I work with (the one im thinking about has a boyfriend but her bike is hella slow she could use it) because its just taking up space and I don't want to give myself the opportunity to ride it anymore, and im not gonna put the spinergies on that bike even if they are more suitable for a small bike.

John,

I hadn't known of Ken M until your post. His Wikipedia page says:

Kenneth McCarthy (born c. 1980),[1] popularly known as Ken M, is an Internet troll known for his comments on news websites such as Yahoo! and The Huffington Post. Unlike the more common associations for the term troll on the internet, Ken's comments are usually benign, with his comments displaying a complete lack of understanding of the featured topic, while other commenters take him seriously.

and:

Ken M worked as a copywriter for Comedy Central and a columnist for CollegeHumor[1] and started posting to comments sections as Ken M in 2011 on various websites, mostly Yahoo! and The Huffington Post.

This is how I perceive Larry; somebody's creative outlet. Thanks for the reference.

Toni Rominger was a Swiss professional rider (he won both the Tour of Spain and Italy) that used 650C wheels during some stages of the Tour de France. Production companies use 700C wheels for small bicycles because of accounting reasons and not because they work better. In order to get around the toe overlap problem, they design the frame with a steep seat angle and very shallow head angle. Toes will avoid hitting the front wheel with that design but it doesn't avoid that it is a poor design. Companies may compromise other frame design aspects like raising the BB height too. This makes no sense as it is likely they will prefer shorter cranks that will allow a lower BB height.

There was a time when some Japanese bicycle companies were making production bicycles with 650C wheels. These were phased out for inventory reasons. There weren't enough short people buying them to make it worthwhile to continue making them. Too bad.

The way that I make a frame is to 1st do a proper bicycle fitting. I then design the frame around their seat and handlebar position. If I am making a frame for a good recreational rider I want their BB height to be as low as possible (unless they ride in fast pace lines pedaling through corners). Their BB height will be based on their crank length. This BB height will be the same whether they are using 650 or 700C wheels. Often small riders want to have toe clearance and this is where smaller wheels becomes essential. Women in particular find that they are not comfortable riding a bike with a steep seat angle.

Here is a picture of the 650C bike I made and painted for my daughter. She is tall enough at almost 5'4" that I could have made it with 700C wheels but 650C work better for her.

The 2 tone gray paint with white and yellow pearl accents I thought worked well with the Dura Ace colors.

Larry overpaid for those wheels. I have a 650c rear for one of my lowracers. I got it about 15 years ago for $175. Note that these wheels have a rep for disintegrating, especially the front for some reason. Probably why I got a read only and not a set. If they hit a pothole, the joint between the rim and blades can loosen and eventually cause a catastrophic failure. If you use them, inspect them before every ride. Although I really like the wheel, I have a backup wheel that's ready at a moment's notice.

Yes, you will need a 26" bike, most likely a tri bike or maybe a road bike for a smaller person. The brakes on a 559 mountain bike will move far enough to work on 650c, but then it'll be the wrong geometry. Anyone who questions that they might be 650B is a newb and just doesn't know better. Forgive them.

On my daughter's frame, I carefully positioned the rear brake bridge (and the length of the fork) so that by taking off the 39/49mm brakes used with her 650C wheels and replaced them with 47/57 mm brakes instead, I could use 559 wheels that would allow for wider tires. Of course it is a bit of a bother and expense to make those switches (but not that much bother). However this change makes her bicycle more multi-functional so she can use it as a gravel bike instead of a fast road riding bike if she wants.

Nice looking frame, did she get to pick the colors? Do you make forks or is that a cf fork? Would you use a different wheelbase depending on the wheel size?

Doug Fattic 

Yes she picked the colors after listening to my suggestions. Yes it is a carbon fork but I usually make forks. I have my framebuilding class students make their own forks as well. It is a skill they will need to know if they want to make more in the future. I did make the chainstays on her frame a bit shorter than if I was using 700C wheels. She is a very fast and fit girl and I made this bike to fit how she likes to ride.

Are you qualified to repair carbon fiber wheels? Given your track record if you mess with them then please don't sell or give them to anyone but the garbage man.

They already sound like a liability, and I'm not looking forward to your post about how they failed on you mid ride.

This is not that kind of forum, guys. You must have a paid membership to sell anything on these forums, but even then you can sell items only in the marketplace forum.

I have nice epoxy at work and am set up to degas it, shouldn't hurt and it should give a visual indicator for if the nick is getting worse.

Looks like I picked the wrong week to stop sniffing glue.
