• Pondering dumping my rim brake bike and upgrading to discs but as the groupset is rim brake (ultegra 6800 di2 if that makes any impact on the question). I was going to use something like Juintech. Anything out there better?

  • Don't really want to have to buy new shifters if I can avoid it. Feels like the gateway to another groupset purchase as I can get a 105 di2 group for 800 euros.
