The Zimbale Leather Saddlebag is just the right size to hold a Lezyne Pressure Drive mini pump, an inner tube, and some tire patch supplies and still maintain the leather and steel retro look. (www.zimbale.com/Front/Product/?url=Product&product_no...)

 

Finally, a couple of somewhat unusual features of the bike include:

 

(1) the M179 STI handlebar is designed specifically for Shimano STI levers (store.somafab.com/nittom179bar.html), and it flows very nicely into the Ultegra controls. It also maintains a “classic” look for the bike.

 

(2) a 46/30T Sugino Compact Plus+ OX801D crankset (www.suginoltd.co.jp/english/ox801d_main_english.htm) was mounted on the Cinelli Supercorsa frame along with a Shimano FD-CX70 cyclocross front derailleur. (In case you are wondering, the Sugino Compact Plus+ OX801D crankset is a higher end crankset and costs more than an Ultegra 6700 crankset.) According to the Shimano web site (bike.shimano.com/publish/content/global_cycle/en/us/index...), the FD-CX70 is designed for use with top gear chain rings of 46-52 teeth and has a maximum capacity of 16 teeth. So, it works fine with the 46/30T crankset. The FD-CX70 is also compatible with current Shimano ST-6700/ST-5700/ST-4600/ST 10-speed road shifters as is the Sugino Compact Plus+ OX801D crankset. That means that the combination of the Sugino Compact Plus+ OX801D crankset and the Shimano FD-CX70 front derailleur works with Ultegra 6700 shifters and the Ultegra 6700 rear derailleur and an 11-28T cassette.

 

The combination of a 46/30T crankset and an 11-28T cassette gave a top gear of 109.9 gear inches and a low gear of 28.2 gear inches. For comparison purposes, a standard compact 50/34T Shimano crankset with a 12-30T cassette would have given a top gear of 109.5 and a low gear of 29.8 gear inches.

 

A 12-30T Shimano cassette could have been substituted in the Supercorsa build, which would have given a reasonable top gear of 100.7 gear inches and a low gear of 26.3 gear inches. That gearing is on my De Rosa Nuovo Classico and is great for general riding up and down hills.
