Dropper Seatpost Internal Cable Routing | MTB Frame Build
HTML-код
- Опубликовано: 5 сен 2019
- This week on the mountain bike frame build, I'm doing the internal cable routing for my dropper seatpost. Truly, I should have done this cable routing step earlier-it would've been a lot easier. But I didn't. So you get to watch me hack my way through it.
Here is the playlist of the whole Hardtail Mountain Bike Frame Build-I'll keep adding to it as we go: • Building a Hardtail MT...
Dropper seatposts are relatively new, and there's no single agreed-upon standard for how to route the cable. The cable needs to end up INSIDE the seat tube. I decided to replicate what I've seen some other steel frame builders do: I brazed on a little reinforcing patch (cut from another steel bicycle tube), and then I made a hole in that reinforced area for the cable to pass into the seat tube. So the cable will come down on the down tube and then pass into the seat tube through that hole, and meet the bottom of the dropper seatpost in there.
This was a difficult task with the seat tube already welded into the frame and without the right set of tools at my disposal. In the end, I tried a few different tools to get the job done-drill, end mill, hand files, and Dremel.
At the end of the video, I also talk about what I'm doing for paint. I'm using some rattle cans from Spray Bike. They were nice enough to give me these cans free as a sponsor, so check them out: spraybike.us/

awesome stuff mate, if you get bored of the spray.bike spray job let me know I paint it for you happily, would be an honour. I recommend epoxy primer if you have access to it. adhesion is amazing and dries rock hard after a few day, best primer to paint on. Love all your build videos, I have started painting bikes about almost 2 years ago, it is a lot of fun but involves as much work and preparation as building the frame itself to the a proper job. Peeling off stencils and polishing are my favourite bits, love to see the bike come to life after sanding the clear. Keep up the good work mate!
Nice retro solution Joe. Really looking forward to your Spray.Bike paint job. I too am going to give them another go but this time with a black clear. I noticed they've since updated their site with more accurate color swatches which is wonderful. I think think they care about their customers and are responsive to them. Also they have a steel primer which wasn't around when I painted the long tail. The site says not to use Acetone for prep! So watch out for that. Cheers!
I don't know why they say not to use acetone but I did anyway and it was fine. It evaporates away very quickly so provided you wait a few minutes I don't see the harm. I suspect the solvent in the paint may be acetone anyway as it kind of smells like it. I found the main thing was to respect the spraying distance-- about 20-25cm away for the primer or it runs, but only about 10cm away for the actual paint or it goes too powdery, and then 20-25cm again for the clear so you don't get puddles of solvent dissolving the colour coats.
Love your vids and frames mate. And love the rattle can!! I have always rattle canned my bikes with good results, but there seems to be such hate for it in the bike community. It’s such a good way to do something stupid and loud and fun and not have to worry much about it. Rock on buddy.
Awsomnes 👊👍
How do you level the frame after welding?
Back in the old days we dropped our post with a quick release.
Back in the old days you didn't have RUclips either
I bought a frame and it didn't come with grommets for the routing so the cable housing slides into the frame ruining it. Is the frame useless or is there another way? My only idea left is to use a hardening epoxy putty and make my own grommets. I know it would work but it would be a permanent thing.
My opinion is that "Painting Is A Crime" when it comes to bike frames. Give her a nice clear coat with X2 clear metal primer. Its a great product and you and the rest of the world will be able to see all of your mistakes as you Shred the Gnar.
That would be fine, too, but I’ve done raw steel. I’ve never done a funky, fun paint job like this.
@@cobraframebuilding As long as your conscience can live with committing that crime...Of course I am joking. I am always torn because I love laying down beautiful paint but I also loathe covering up the raw beautiful steel. At the end of the day the discernible eye will see our mistakes anyway. Looking forward to seeing what you come up with.
