This is an N+0 story.

2 disclaimers: I don't have a white garage door to photograph in front of. I've spent most of my riding life on MTB's.

This is a remake of my old (2003 Diamondback Response) road bike into something I find comfortable at the age of 67. It was made up in part from stuff laying around the shop and may get some new bits as time and money allow.

Aluminium Frame from 2003 Diamondback Response.
Wheels from a Diamondback Master.
16 speed New generation Sora flat bar touring bike gear (easier to buy from European sources than to find at the LBS)
Sora 9sp compact double external bearing crankset.
Shimano 8 speed road/touring cassette 11/32 with evenly spaced gears instead of the large jumps between the lower gears that mountain bike cassettes have.
25mm tires that seem to take much of the edge out of the ride that the former 23's had.
Tektro racing division RX40 brakes (roughly ultegra equivalents)
WTB mountain bike saddle which has always been one of my favorites. It fits and it's comfortable.
Ritchey adjustable stem which will get changed out when I find roughly the same rise/length that pushes the bars out about 1 bar diameter. (its one heavy slug but it works to find the right bar position)
The bag is replaced by a light duty seat post rack when we travel.
Eventually the MTB bar grips will be replaced by bar tape because I am running out of bar room and I think I'm going to need bar ends for heavy climbing.

Not bad for an old geezer road bike for an old MTB geezer.
