Merida Scultura 5000: Full Ultegra Di2 6870 Groupset

On two of my bikes, the Wheelsport Fantasy mini velo and the Merida Scultura 5000 road bike, there is a mix of Ultegra and Dura-Ace components. This is mainly due to me getting these parts at different times, and trying out different setups, which is why there is no complete groupset on these bikes.

I decided to switch the components on these bikes, so that I can get a full groupset on each of these bikes. The function would be similar, but the appearance would be more consistent and coherent.

Starting with the Merida Scultura 5000 road bike, the current setup is mainly Ultegra 6870 Di2, with Dura-Ace brake calipers and Dura-Ace crankset. Since the Ultegra Di2 system will remain on this bike, I would bring over the Ultegra crankset and brake calipers which are currently on the Wheelsport mini velo, so that this Merida road bike has a full Ultegra groupset.

Before switching the components: All Ultegra except for crankset and brake calipers, which are Dura-Ace.

52/36T Ultegra crankset installed on the Merida road bike. I would have preferred the 50/34T crankset, but I had already sold that crankset.

Full Ultegra 6800/6870 drivetrain! Looks better with components from the same series.

Dura-Ace brake calipers are also changed to Ultegra. Quite a straightforward swap.

The brake pads had to be adjusted, but otherwise the swap is easy. Performance is almost equivalent to Dura-Ace.

I think that I have finally settled on a good setup for the Merida road bike, with a full Ultegra 6870 Di2 groupset. Having experimented with a mechanical Dura-Ace 9000 groupset on this bike, I still prefer to have the Ultegra Di2 groupset.

This also means that all the Dura-Ace 9000 components will be going onto the Wheelsport Fantasy mini velo, but that is a story for another day.
