Budget dropper post

[Zorro5614]

Hi guys

 

Sorry if the question has been asked and answered befort

 

Looking for a budget, reliable dropper post. 31.6mm and about 120mm of travel.  Know lots of you recommend Lyne, but here are my options.  Like Rapide components and the price is excellent, but uses a shim.  Would appreciate any advise

My personal opinion would be to go with the Satori!

Contact stoke. See what Droo can do for you. He has some droppers to sell

I have a Lyne Externally routed dropper and have not had any issues yet. As you mentioned the diameter of the post is 31.6mm so no need for a shim. They also sell the service kits and even replacement cartridges on their website which is a plus for me and they are not that expensive. 

 

I cannot comment on the other as I went with Lyne as they had the correct diameter post and the cable attaches to the collar of the post so no moving cables for the externally routed post.

If you are buying new buy Lyne. Have them on 2 of my bikes now (going to get a 3rd one for wifey's bike too). They work consistently well, easy to service, and Lyne's after sales service is excellent.

 

Premium product at budget pricing.

Both my son and I are also using the Lyne Droppers; for nearly a year now.  So far no problems.

Practically identical to the Lyne. I have one and love it

Darn good price at R1600!

I use the Rapide, you don't even notice the shim. I had a problem installing it and had an expert on the chat within 1 minute of going on the website. Also had a warrantee problem and the cartridge replacement was couriered to me.

 

With the Rapide you have to drill the frame, but I much prefer the internal. My frame is carbon out of warrantee.

 

I am very happy with it, so going to stick with Rapide for a while. I had a cheap ebay one for a few years, really not worth it compared to a better one like Rapide. Rapide also sell replacement cartridges, so after a year or two you are probably going to need one.

Thanks guys.  Been chatting to Wayne at Rapide and everything seems very positive.  The clamps will even fit my 7x9 carbon rails

 

Just want last thing regarding carrying spares in a strap saddle bag on dropper. I usually have a spare tube, Co2, multi tool and plugs.  Thinks this all adds up to close to 500g.  Will this negatively effect the dropper?

I would avoid a post that requires a shim. The shim will not allow even clamping force to the post and worse this will be distributed over a greater length of the post, meaning more of the post is ovalised. Result could be shorter life to bushes and key = frustration

if the bag contact the post at any point, don't fit it. It'll restrict the movement of the post, and rub on the stanchion. Not a lekker thing. 

 

If it's only on the saddle rails, keep it, it'll be fine.

I don't understand this, the shim is a sleeve that goes all the way around the post and made of metal. You can clamp it as hard as you want.

[DieselnDust]

when you clamp the post, pressure is only applied at one point. That pressure is transferred to the shim and to the post itself. If the shim ovalises it places uneven pressure on the body of the post, more so than if the post was clamped directly meaning that the post can ovalise down where the bushings are . If that happens then the post is going to see high wear and stiction.

This is why most dropper manufacturers recommend no t using a shim to size the post to the frame but to rather purchase the correct size post for the frame.

Maybe Wayne from Rapide can comment on this, its not something that I would worry about. Rapide are obviously happy with the shim concept. I did have a problem after a month with my post and the response from Wayne convinced me.
