Campagnolo Chorus

Price Paid:  $0.00

Bike Setup:
2006 Litespeed Tuscany with full Chorus (but not for long!)

Summary:
This is for the 2006 Chorus carbon post, purchased for a new bike. Don’t buy this post.

The problem is in the head design, which uses very fine grooves to (supposedly) help keep the saddle angle and fore/aft position fixed. They simply don’t work, and the saddle slips continually. I have cranked the fixing bolt extremely tight, to the point I worry about either breaking the hex wrench or stripping the bolt threads. It will hold for a couple of days or a couple of weeks, but inevitably when I hit a sharp bump there’s a loud and terrifying CRACK and the seat slips. After this happened a few times the grooves started to get worn and the slipping has gotten worse.

The problem appears to be that there are two sets of grooves, one on the left and one on the right. It’s impossible to tell if you’re in the “same” groove on each side because they’re so finely spaced. If the grooves aren’t exactly matched side to side, then the seat mounting plate is actually sitting at a slight angle (you can’t see this). That means the grooves aren’t fully engaged so no matter how tight that bolt is, the head slips. It may slip even if they ARE correctly engaged – I can’t tell as I’ve never managed to keep it from slipping for more than 3 weeks.

Strengths:
Pretty

Weaknesses:
Doesn't actually work!

Summary:
datona/centaur version with steel tube.
I used this for 1 year.
It provides large setback for cyclist.
Reliable. It has no fatal defect.

Strengths:
nice look.
It has specially designed surface so it prevents scratching.(from seat tube etc)
Lightweight steel tube is stronger than most aluminium seatpost.
Very secure seat clamp, it prevents slip.

Weaknesses:
It gathers some rust inside, so you have to greese.
Angle adjustment is quantized, so it can be a problem but I think that's enough.

Summary:
This review is for the steel shaft Centaur/Daytona version. If you are looking for a seatpost with a decent amount of setback this is a good choice. While the clamp design is not truly infinitely adjustable, I did not have an issue getting the angle I wanted.

Strengths:
strong and simple
clamp design resists slipping
decent setback
large clamp design very secure

Weaknesses:
not infinitely adjustable
not the lightest
