For this trimmed down sportscar ride, I tightened up the geometry to get the overall center of gravity lower and a sharper steering angle.

Using a frame with the stock tipped-back geometry intended for long suspension forks was an opportunity to use an old school, pre-suspension era, hence shorter, chromoly fork. I removed five pounds of low performance fork and replaced it with ounces of top quality fork.

This then tipped the geometry forward and slightly lowered the bottom bracket. For high rpm I used slightly short cranks for me, 170mm, and they helped with the ground clearance.

This all really livened up the handling. This is a sharp handling precise controllable machine.

To further lighten and simplify, and to eliminate poor performing components, removing the front derailleur and sprockets converted the bike to a 7 speed with a single on the front (46). A wide range 7 on the rear (11-30) with Deore XT derailleur.

For damn good security: a good mini u-lock, a bolted seatpost, and a locking skewer on the front wheel. The system is easy to use and protects against most thefts and almost all stripping.
