I'm hoping to install mid August and get some reliable miles on them before the fall big ride.

51 mile ride around the BWI airport and down to Annapolis. To get 50 miles I had to do the airport loop twice. It was predicted to be a hot day so I got an early start but still got to 90° by the time I wrapped up the ride. Still managed to average 14 miles an hour. Good practice riding in the heat. This is the longest ride in a long time on the Porsche Bike S.

My 2004 Porsche Bike X (large frame size)
2004 Porsche Bike X (small frame size) recently sold on Germany eBay
2004 Porsche Bike X brochure.
I ran across another Porsche Bike X that recently sold on the eBay site in Germany. The Porsche Bike X is an ultra rare Porsche bicycle with only 250 produced. The bike sold on Germany eBay was a small frame, mine is large. Interesting to see the subtle differences between the small and large frames. I still have my suspension forks and seat post if I ever want to convert mine back to a hybrid bike. Also attached is the original product brochure.

My new friend Andy from the UK rebuilt his 1996 Porsche Bike S. He completely rebuilt the forks with new elastomers and total clean up and installed new tires. We have been emailing and comparing notes for a few weeks. It's great to see others keeping their Porsche bicycles in top condition!
Trying to outrun Tropical Storm Fay, I set a new personal best on my 40-mile BWI to Annapolis and back course. That wasn't my original intention, but watching the clouds roll in I thought it best to get a move on. Riding fast worked out well as it poured rain the moment I got home! The newly fixed front derailleur performed well, but I did need to adjust the outside limit on the outer chainring. Other than the incoming rain, the temperature and cloud cover made a perfect morning for a long ride.

The chain fell off the outer chainring on the 1998 Porsche Bike S front derailleur during a ride last week. It was a nasty mess with the chain all contorted. Fixing the chain, I continued on my ride. From that point, the front derailleur seemed out of alignment causing the chain to slightly rub on the front derailleur cage in certain gears. The rubbing was a slight inconsistent mechanical grinding sound. I thought maybe the chain-off incident caused the front derailleur to go out of alignment. But after many attempts, I couldn't get it back into alignment.
Poking around I noticed the derailleur cage could pivot out away from the derailleur mechanism from one corner. It shouldn't do that! Then I noticed the pin that holds the cage to the derailleur frame mount had backed out slightly. Lightly tapping the pin back in through the frame mount, the derailleur cage snapped back into place.
The images below show the derailleur cage and pin.
NOTE: This specific pin mechanism system is only on the 1998 Porsche Bike S with the Sachs Plasma derailleur. The Sachs Neos derailleur mechanism on the pre-1998 Porsche Bike S is completely different.
Front derailleur cage should swivel out evenly and securely. If the right (front) side swivel's out more than the back, the pin has backed out.
I tapped the head of the pin completely back in with a screwdriver and mallet, see image above.
The image above shows the pin through the derailleur frame mount, as it should be positioned.
