Dropper Posts: Things are hotting up

[slickandtyred]

Ordered an internal routed dropper. Going to have to drill hole near bottom of seat tube or possibly drill through bottom bottle cage hole.

 

Advice from those who HAVE done this would appreciated. Would you do it again?

Isn't Pro Koryak owned by Shimano?

yes, it's their accessories and non drivetrain componentry

love the idea of an electronically actuated dropper. Makes so much sense.

Also makes swopping one post between multiple bikes a breeze, is the wireless via Bluetooth?

Thanks AlanD. I read the other thread. I note you drilled on the back side of the seat tube. Have you not had debris ingress being splashed up from rear wheel ?

I think so, yes.

What i did was tape the hole as well as i could to prevent debris getting in there. You can buy grommets to try fit in the hole. So far i have not had any issues with it. Can send you a pic of how i taped it up if you like

[slickandtyred]

All good thanks. Will probably do the tape/grommet option. Drilling into the back of the tube is a whack easier as far as access for the drill goes.

 

Awaiting delivery of the dropper I ordered

So much easier at the back and the routing can be done neater. I route the cable under the bb, piggy backed on the rear RD cable and up into the FD cable guide thingy. Worked out lekker

The Tmars mechanical dropper. 110mm travel.

 

Can you get the service kit?

So its been 18 months using this thing. Never took it off the bike since I installed.

Not one service. I figured I'd do that once its starts giving issues. Which it did...

 

The last few rides I noticed some side to side play. Then on Saturday. Poof!

Side to side play turned into a full rotation of the stanchion. Massive amount of twisting till you somehow manage to click it in one of the 3 settings. Which minimized the play but still a bit of a nuisance. 

 

Turns out the 2 plastic guides inside were destroyed. These guides slot into the stanchion and travel along a groove inside the actual post. Acting as kind of a washer between the two. Its purpose. To keep the stanchion from twisting while moving the post up and down. 

 

If When they break. You'll need to buy the service kit to replace them.

But importing them takes forever and they too will break eventually.

So here's what I done...

 

Fashioned some home made replacements out of aluminium. Just a little grinding and sanding to get them to size and presto

Since I stripped the thing I noticed one or 2 other things as well.

First of which. How ridiculously simple this contraption it. There's no way you would struggle to put this thing back together. Its pretty straight forward and anyone with common sense can throw it back together. 

 

Secondly. The amount of mud, grime and sand that gets in here is astonishing. Well, at least 18 months worth. It mixes with the grease and cakes everythin into a gritty soggy mess.

I recomend opening this thing at least every 3-6 months for a good clean and re grease.

 

Get rid of the plastic spring cover too. Its suppose to protect the ferrous spring from rust and damaged but what it actually does is collect mud and moisture allowing your spring to be exposed to moisture constantly. I noticed some slight surface rust on my spring because of this. Not enough of it to worry though. Managed to polish most of it off. Its also a pretty simple spring and a non-ferrous replacement should be easy to get just about anywhere.

 

Moving on. Cleaned everything. Re greased everything with copper slip and everything was back to normal. The post functions better that ever and there is no twist or side to side play.

A mechanic made the guides for me. Took him a while to get them fitting snug with enough tolerance to allow free movement.

 

If anyone else wants the same cheap as chips mod and service to their Tmars/Forca dropper. Please let me know and I'll forward you his details.
