Helpful videos about frame geometry

6 Mar

Brought to us by the lovely ladies at terry.  (note this is for a road bike but much of this is still very useful to any rider)

They are still adding videos about geometry but this could be pretty helpful, you can find them here.  The bikes they sell may not be what a novice want but they do make well live bikes as well as saddles. (plus size cloths too)

On choosing a bike: Part 2

5 Mar

Wheels can make quite a difference. The most important thing for a larger rider to consider is wheel strength. If your wheels aren’t strong enough they can go out of true. When a wheel is in true it is perfectly straight. If the wheel takes a hard hit it can get slightly bent or a spoke can break. Breaking a spoke will also affect the tension of the wheel making it go out of true.

The rim material is also important for braking. If you live somewhere rainy you want to avoid steel rims because you wont be able to break as easily. Aluminium is a much better stopping surface than steel and pretty common with newer bikes.

The wheel size will affect the durability. The smaller the diameter of the wheel the stronger it is. 26″ wheels are stronger than 700c wheels. The main problem with the smaller wheel is something called rolling resistance. See Sheldon Brown if you want to get technical. Rolling resistance isn’t much of a problem unless your aiming for speed. It’s also easier to get going from a dead stop with a smaller wheel than a larger ones. There are other wheel sizes but these are the most common you will see.

A slick 26inch tire is going to be much easier to use than knobby mountain bike tires. Unless your riding off road you don’t need need the knobby tires. secondly keep your tires properly inflated and you should be in good shape. As far as pumps go, if your not going to carry one with you don’t buy a travel pump buy a floor pump they are much easier to use.
Rims:

When looking for rims try to find a touring rim. These are often double walled are really strong. Again made for carrying a load. The rear wheel is the most important wheel to for strength since it carries most of your weight. I am a huge fan of Mavic A719 for a 700c rim. They are super strong.

A strong rim is especially important if your buying a 700c because they are more fragile. If you have 26″ rims they are stronger and you may not have to consider further action.

Spokes: The more spokes you have the more your weight is distributed. If your can find a wheel set with double butted spokes they will be even better because they disperse the load over the spoke better.

If your are buying a brand new bike you may not have control over some of these thing if you get a bike that’s already built up. Wheels with double butted spokes must be build by a person thus making it much more expensive. Make due with what you think you’ll and if it becomes problematic you can invest in a new wheel or wheel set.

Fatties for Bikes?

22 Feb

Ok, after talking to my partner in crime we decided a wiki would be the way to go. I don’t want to skirt around the issue that it is a wiki for fat people on bikes to share knowledge specific to weight and cycling. I was thinking of calling it “fat girls on bikes” or “fat girls for bikes” but I don’t want to neglect fat men from the forum.

I suppose the info is the same for the most part. It could be directed towards women but have a men’s section. Yes I like that, I thing we know there are a few less things for women than men out there. My knowledge is centered around being a woman and those of future co-conspirators would be as well.

Things to discuss:

Choosing the right bike or parts

Plus sized clothing

pacing

respect from your local shop.

Oh, how I will miss the NAHBS + other events

8 Feb

For those of you not in the Portland area The North American Handmade Bicycle Show is this weekend. I was elated that it was also on Friday since I work weekend (the exact hours of the show). I look up ticket info and it turns out Friday is for press and industry only. It’s a pity but then I can’t afford one anyway. The good news is there is still plenty of fun to be had outside the show!

This weekend there will be plenty of bike fun,

Tonight is the Midnight Mystery Rides birthday and benefit ride for Leo Check it out here.

Saturday at Plan B (1308 SE 8th) there is a benefit for bikeportland.org that should be awesome. They have prizes and 2.50 New Belgium so I am going to be there. So if you see a fun looking fat girl feel free to say hi. info here.

There are a bunch of other things going on around town but these are the two that I’m going to rep. Look at the coverage on bikeportland.org if you want more ideas (roller races for frames, stuff like that).

Other upcoming events include some free workshops at Citybikes:

Sunday, February 10th: Bike Mechanics for Pansies (aka the non-mechanically inclined)
Are you afraid to take off your back wheel? Do you not know what a quick release is? Are you intimidated by bike shops, but want to learn more about how to maintenance your bike? We will cover flat fixing and q&a. fun!

Rebuilding the wheel

20 Oct

I was getting sick of being the broken spoke bandit so yesterday with a friend a new rear wheel was build.  We used a tough touring rim and butted spokes.  A new used hub and we repacked the bearings.  I also want to clarify that by “we” I mean mostly my friend.  I have never done these particular before so it was nice to see how in works in person.
