Haven't gotten to the scary/good stuff yet, but here is what has happened so far.

Package arrived today, opened it up for a quick peek, new parts are so Pretty!!!

Went for one last ride without a dropper post.

Then I decided to open up and inspect everything, which included weighing things, of course!

Original Carbon 410mm post was 226grams, I had 7+ inches of post inserted in the frame, so I could have cut this and probably dropped it closer to 200grams.

Now the New post is not just the weight of the post, but also cable, lever and bracket.

The post itself weighed in at 479 grams, when advertised was 467 grams.
Lever was 27 grams, bracket was 11, for total 38, advertised was 35.1g.
Cable and connectors came in at 76grams.

So total weight is 581g, compared to advertised 550g for the 375mm with 125mm drop. This equates to a gain of 355 grams. EEEEEK, oh well, I can personally stand to lose 20 lbs, so I guess .78% of a pound isn't terrible.

Because this will require drilling of the frame, I decided I would fit the lever first, and test fit the cable to decide where I want to drill. This is about where I got to this evening. I have now decided where to drill and will do that and the remaining install tomorrow evening.

NOW for pictures.

Hole is going to go in the center of the red pin striped area. Gives good range of motion and I think will look clean.

This is from the Santa Cruz cable guide kit. Shouldn't require anything fancy, I think either a round or slightly oval hole will work fine.

Picked up today after work and went right in for the hard/scary part, drilling the frame.

Image20180727_172001.jpg by Matthew Kogan, on Flickr

1. Picked a location that seemed logical and had good cable routing.
2. Taped to prevent chipping.
3. Started drilling. Started with a small pin hole size drill and worked my way up to 1/4". Once I was at 1/4" I did one last pass at an angle that matched that of the cable grommet.

4. Test fitted Grommet.

5. Inspected frame and tried a few methods to get the cable routed internally. Ultimately ran the cable from the seat tube up to the new hole in the downtube.
With this model seat tube you end up cutting the end off the cable so direction wouldn't matter much, although I found it easy to put a slight bend in the raw end of the cable to help make the turn at the bottom of the seat tube. Then gently pushed the cable up until I could see it through the new hole. I then used a magnet to "guide" the end of the cable to the hole. Once I had the end of the cable, I ran the housing down over the cable, being careful not to kink the cable at the turn from downtube to seat tube.

6. Attached the dropper post connection hardware.

7. Test fit the post, pull extra housing length out the front end, measure twice and cut the housing.

8. Insert cable and connect to post connection hardware. For this post you end up cutting the normal shifter "ball" off the end and using set screws to attach.

9. Add air per this dropper post instructions.

10. Rough fit post to height.

Image20180727_190910.jpg by Matthew Kogan, on Flickr

11. Connect cable to lever, trim cable and install cable end.

Image20180727_190913.jpg by Matthew Kogan, on Flickr

12. Lightly grease seat rails to avoid squeaking.

Image20180727_191110.jpg by Matthew Kogan, on Flickr

13. install seat

14. Final Fitment, Up, down and with saddle bag. Might end up adding a Wolf Tooth Valais https://www.wolftoothcomponents.com/collections/accessories/products/valais-25

1. You are a funny mothereffer Mathew
2. Thanks for the post
3. Don't fret about the extra post weight. Just think how much you dropped by drilling out all that carbon...
4. You got any race vids posted? (car, not bike).

Yeah, cause that 1/4" hole removed a lot of carbon.

Here's a couple track videos. Haven't actually "Raced" lately, but have done a few DE's.
This one is most interesting at about 20 seconds.

And back to the post that this post was posted about.

I should have done this a LONG time ago. It's like a new bike. So much more fun and lively on the descents with the seat dropped. As a secondary, it seems to have resolved some noises from the saddle. I had a 0 setback post before and my saddle was mounted about as far back as possible, causing creaking and popping. The new post is a 25mm setback and the saddle now mounts in the center of the rails.

Some Pics on the trail.

I know! Biggest issue was this was kind of a weight weenie build and the frame had no provision for either internal or external cables.

Heck, I was actually an early adopter of dropper post on my 2013 Santa Cruz, with the first gen externally routed Reverb.
