Attempting to install a 700C wheel on my 26" rear frame
 
As my name might imply, I have built a DIY recumbent using a 26" donor Huffy mountain bike from my youth (>20 years old) and a smaller 20" freestyle bicycle for the front. I think this is the right forum to find some friendly folks to help me figure out this customization issue.

The rear wheel's axle has seen better days and has about 3/4" of play. I could still test ride it, but I know it's not safe that way and have only test ridden it about a half mile total.

For an upgrade, I bought this 700C rear rim from Amazon and a free wheel gear cassette to go with it with some nice gear ratios for the recumbent.

I know that the 700C is larger diameter than my older 26" rim, and I am prepared to move the brake mount location to accommodate the new rim.

However, here is my question, the threaded axle does not stick out far enough for me to put a nut on either side. Does this mean I need to buy a quick release (e.g. this one) or is there another solution?

I don't know much about bicycles.

Lastly, the recumbent weighs in at 62 pounds. I am about 215 pounds. Can the 700C rim handle that kind of weight? It is possible that, aside from being old and well used years ago, the weight is what destroyed the old rim axle bearings.

Thanks in advance!

might just need a longer axle and re assemble the axle cones and etc. around it.

I'd have to see what kind of wheel you are talking about , and how craptastic or better it may be.

Seek out a Bike shop since your knowledge is lacking.

I linked the rim I bought in my first post. Please have a look.

I'm a pretty productive general DIY'er. Will swapping out an axle cause little ball bearings to go flying or are they in a bearing race?

I'm trying to avoid a bicycle shop because I probably won't be buying anything from them to save a few bucks. This project has been on the cheap for my wife. I listed my weight because I test ride before she gets to risk herself on it. :)

That is a quick release wheel, so you just need a quick release. The one you linked to is for a front wheel. You need one for a rear wheel, which is longer than the front one.

Thanks dsaul for the reply. Was a "duh" moment as the quick release I linked says it is front in its title!

Here's another. The wheel is for an 8 speed so I think this one will work. I didn't notice, but it looks like the center of my new wheel's axle is probably empty and this quick release will go through it. This eases my mind a bit on mounting that rear axle to the recumbent if I am correct.

The only other piece I need to fab up is a gear spacer because my gear cassette is only 7 speed so there is 1 speed worth of slop in the assembly.

Better yet! I was looking at the wheel I bought on Amazon, being a bit annoyed by the picture showing the release but my not getting one... Well, I went outside back into the garage and looked in the bottom of the box and there it was!

Looks like I can continue this project tomorrow! Time to go buy a new 700c tire and tube and fab up that gear spacer.
