Java Freccia Carbon Mini Velo: Part 7 - Dura-Ace 9000 Groupset

The Java Freccia carbon mini velo is almost completed! All that is left to do is to fine tune the adjustments and it is ready to go.

Looks great!

During my test ride, I found that the riding geometry is really low and aggressive, due to the low handlebar height. In fact, after comparison, the handlebar height is even lower than the Merida Scultura 5000 road bike! It is too low for comfort, which is why I decided to flip the stem to make it more comfortable.

Controltech 80mm stem was originally installed with a downward tilt

After flipping the stem to be upward tilting, the geometry is better and almost the same as the Merida road bike

Full bike weight is only 6.7 kg inclusive of pedals!

Full specifications of the bike. I did not use any boutique super lightweight components, all can be found easily. Theoretical weight is equal to actual measured weight. Only 6.3 kg without pedals!

Same for the rear wheel. Braking power is better than expected.

Yet another bike building project has been completed, and I am very pleased with the results. This mini velo is very lightweight at only 6.3 kg without pedals. Also, it rides really well, despite the short chain stays. Braking power using the Ridea brake pads is actually quite good, and I don't miss the SwissStop brake pads. Shifting performance with the Dura-Ace groupset is of course top class, while the Wheelsport Smart 1.0 451 wheels roll really well.

Despite my initial worries, there has been no creaking sounds from the press fit bottom bracket, while the integrated seatpost clamp has not given me any problems with slippage. Other than the insufficient reach from the road brake calipers and the slightly tricky internal cable routing, there has not been any real issues with the installation.

I have tested it while riding with some road bikes, and this mini velo actually feels just as fast as my Merida road bike! The weight difference is felt most during climbing, where this bike just keeps moving instead of dragging you back like on some heavier bikes. Carrying the bike up the stairs or anywhere is a breeze due to the low weight. It is currently my favourite bike to ride as I have rediscovered the joy and fun of riding a mini velo!
