I like riding single speeds on weekends since they give me a good workout. Here's my Schwinn Super LeTour that I had converted to single speed.

And my beloved Dawes SST I bought from BikesDirect. She came with a flip-flop hub so I can go Single-Speed or Fixed Gear but I left it Single-Speed. I just can't seem to get the hang of Fixed Gear.

There are afew group rides coming up in my area so I've ordered a Mercier Galaxy Steel which will be good for long hauls. I'll still use my single speeds for shorter rides but specifically ordered the Mercier Steel for rides of 60 to 100 miles.
I use SPD pedals on my Schwinn conversion and switched out the SPDs for CB Eggbeaters on my Dawes SST. My new Mercier Steel will get SPDs also.

PS: I'll eventually switch entirely back to SPD pedals for all my 3 bikes. I really just wanted to experiment with Eggbeaters. Eggbeaters are easier to click into but SPDs are (to me) more comfortable on the feet. It's best to use what you're most used to and works better for the long haul.
