Anyone fitted a stealth dropper to an 2018 Scott Spark RC and can advise on the cable routing?
I assume RC is the same as my 2017 plus frame aside from revised grommets.
If so, your bike should have come with multiple rubber inserts to allow you to configure what cables go where you want them
Routing is into ports behind headtube and internally above BB up seat tube.
You get a bit of extra jiggery pokery by removing the rear brake/shifter cable port and even more wiggle room removing the BB.
With any cable post, set the cable outer level with the top of your seat tube and mark where the cable meets the dropper lever at the bars. Now, remove the dropper lever from the bars, measure the amount of cable you need to chop off the bars end (i do this by measuring my BB to rail height then measuring how far the seatpost base 'cable outer stop' is below the seat tube top) then chopping that length off the end of the mark at the lever end.
Run your cable, tighten everything then insert the post and ease the outer through as you drop the post into the frame.
Thanks Bearback, useful advice. I feared it wouldn't come to removing the BB! I'll give it a go.
I did it a couple of months ago to mine... Be prepared to be patient if you don't want to remove the BB!
Mine didn't come with spare grommets to allow more cables so I bought some (around £6-£7 from Pedalon).
I managed to do it without taking the BB out, but I loosened the grommets near the head tube, fed the cable down the seat tube (tried both ways).
I made sure the cable had a bend to somehow go around the tight curve near the BB. Eventually mananged to fight the cable through all the others and feed it towards the headtube. Then I grabbed it and pulled it through!
It's never coming back out now!
