Excellent piece of kit. In the past I would have put my bike into the local bike shop to get my gear and brake cables changed. Now with this kit I've saved a small fortune in replacing both set of cables on all of my bikes...well done Park tools.

Just worked a treat on getting housing for an internally-routed dropper post through a carbon hardtail frame. BB area was impossible without the IR-1 (or removing the BB, probably). Whoever designed this tool deserves a Nobel Prize!

Calvin ran out of patience on the Focus, and decided to cut the down tube...

I didn't know Park Tools had this kit--thanks so much! Do you have a video that shows a complete installation of Shimano Di2 on a road bike? I plan to install a complete Ultegra Di2 system on a frame.

Just solve my problem with that! Excellent!

there is always a way, a little heat shrink, string trimmer line, neo magnets, crazy glue make your own( unless the park tool is cheap-unlikely) magnetic couplers will a rough time in a steel frame( thats why He said everything but steel) if your bike frame has a lot of "reluctance" the locating magnet may not work.

Hello, on video Minute 0:51, I am unable to screw the IR piece into my hydraulic brake cable. Any thoughts? Looks so straight forward on video, but I can’t get it to work for the life of me.

my Cube bicycle has a brush in the down tube, am I supposed to remove it before wiring a new cable in? I cannot move cables easily with the brush inside, but I do not have a large opening for operating pliers either (I would need to enter a small fissure and reach some 10 cm inside)

Great kit; a life saver. Anyone else have a problem with the small magnets coming out of their holders? How to prevent this?

If you want a challenge, you should try it on a 2016 Ridley Fenix SL - the bottom bracket area routing is a real PITA

Made my dropper post installed internally by a piece of cake.

[neilfroggycrompton]

do the hydraulic tubes ever get punctured/leak by the metal edges in the frame holes?

[andyvan]

aha thats how you give a bike a colonoscopy!, always wanted to know how they got those cables in there.

[guitarman]

How about Titanium? Will the magnets function against a Titanium frame ? If I remember correctly titanium is not magnetic, but I could be wrong. Thanks.

[lifestyle]

how do you kno if the frame requires outter housing cable?

[Duraltia]

Heh... That Di2 Adapter wouldn't have worked with the ports I had to use to get my Di2 wiring done.

Because of the preinstalled Wiring Guides inside the frame ( CF tubes inside the frame ) and the necessity to have the 4-Port hub located somewhere inside I was forced to route the Di2 wire coming from the Handlebar through one of those tubes exiting behind the bottom bracket and then back into the frame via port JUST barely wide enough to fit a Di2 connector wrapped ONCE with a super thin electrical tape.

Maybe make use of the actual connection inside?

[FloridaBikeVlogger]

if needed, could I just tape the wires together?

[Bonky-wonky]

Excellent piece of kit but having to resort to magnets in order to route cables is just lazy engineering on the part of the bike manufacturer. Either do it right (santa cruz comes to mind) or just use external routing.

For my bike, the tool was of no use. Luckily, it (the tool) was a gift. My cables are stainless steel, barely magnetic. The frame holes are barely large enough to permit the passage of the derailleur cables. There is no tool in this kit that would pass through the holes and grasp my derailleur cables.The brake cables passed with a tool made from a bent and ground down spoke to grasp them and fish them out. The IR-1 was of no use. For derailleurs, I passed a cable backward and superglued a length of thread to it, then glued the thread to the new cable and pulled it back through. No cost. Still a pain in the butt.
