added :
Pro Tharsis 100mm stem, for steerer-installed di2 battery.
Excellent stem, very strong, light and grippy that allows to intall a di2 in a steerer.
it comes with a special steerer expander that secures the battery, a hex key that preloads the headset and a couple of top caps.
I went as far as i could with this one but my whisky forks have some carbon residue inside the steerer, so cannot use it as intended.
With this, you can run a 1x di2 system with only one long e-tube from junction box to rear derailleur, avoiding water ingress from seat tube and a junction box floating at the bottom of the downtube.
