A bit of a random question, but one that would really help me out: I have a frame (size M) on order and I slowly but surely getting all the parts together.
For the brakes/shifters I am thinking of getting some GRX ST-RX820 which come in a "J-Kit" version which come with a pre-cut, pre-filled hydraulic brake line - this would be convenient because I don't have the tools for working on brake lines (yet).
Since I am trying to avoid trimming the brake lines, I'd like to make sure to order the right one - so if anyone has any recommendations for brake line length (especially the rear) please share - thanks!
If i remember correctly there are two options for the rear brake hose. One ultra long for tandems maybe and the other one you should order.
But bear in mind even this break hose is too long. So a cutting tool or super sharp set of pliers should be at hand.
An easy way to get the rough lengh you is to take i.e. a shoestring and work your way from caliper position back to the handlebar.
