doing a 7 or 9 speed, not sure yet, with front hand break and rear "pedal" break..

You know you can't run a fixie with a derailleur, right?

Sturmey Archer is the only way to do it AFAIK-

Not fixie the old school back break, metal bracket you attach to rear stay n hub. always forgot the name.. so you can not pedal and still move but push back on pedals and it breaks.. haven't seen anyone do it but I wanna try..

I've always loved old steel bikes with interesting bottom bracket cutouts; saw this one today at an annual "River Fools" party at a friend's business (cleverly disguised as a weedy lot covered with old Italian & British motorcycles, cool old bicycles, and, um, industrial sewing machines.

Anyone know more about this bike?

It was hanging above one of the shop doors, and Jim came in and whacked me with the door just as I hit the shutter, which is my excuse for the lousy photo. he didn't know anything about it beyond the fact that his wife had picked it up at a swap meet. Lots of very nice, handbuilt touches like recessed chainstays, brazed on cable guides, beautiful longpoint lugs and the only pair of vertical drop outs I've ever seen on a bike of that vintage. And, of course, the big "K.H"cut in the BB. Does it ring any bells with anyone?

Months of work with our city council & parks department by the Prescott Mountain Bike Alliance (I'm on the board & chair our Advocacy committee) have come to this:

The first three loads of high-clay content dirt went in this morning, with a couple of dozen more to go, that will become Prescott's first bicycle pump track, just two blocks from my house. For those who don't know what a pump track might be (I didn't a year ago), here's a sample:

I'm toast.

Rode 62ish miles on the roadie today, including 4K+ elevation gain. Had some nice winds too, just for fun.

We were in the Colorado Springs area, and the route included both Black Forest and Garden of the Gods, with Pike's Peak watching over it all. Needless to say, the scenery didn't suck.

Our very own Fresh Pants has a pump track (much smaller than what you're building) in his back yard.

Our pump track opens to "ride in" tomorrow - I rode the nearly-done outer loop for the first time day before yesterday, and man, do I ever suck at pump track riding! (and no, that's not me in the picture!)

FYI those are a little harder to learn than completely clipless (clip) pedals, since you usually have to flip them over before clipping in (plus I find mine are a little stiffer for clipping in and out of).

And everyone falls at least once while learning.
