I need a nice light weight seat post with a 25mm offset and the ENVE post caught my eye.

The only problem is I want it to be under 150g! The ENVE is 400mm long so I can cut approx 150mm for my application which will help.

Beyond that are there any simple 'tuning' ideas to shave off additional weight?

Has anyone successfully removed the large white ENVE logo from the front of the post?

The other option would be to find a lighter post with a 25mm offset. Any ideas?

I have a zero setback and chopped 170mm off it which dropped 43g if it helps your overall calculations...

That is great info! Cutting off 150mm should drop approx 37g which brings the weight into a more acceptable range :)

Is the supplied through-bolt steel or Ti? If it is steel I should be able to drop at least 5g by swapping to a Ti bolt.

If the advertised weight of 190g is accurate (I use a 27.2mm) these mods should get it down to 150g!

So, other than whacking the stem, replacing the bolts, what else is done to "tune" a piece of carbon ?

As against ww-ism as this may sound, I'd say cutting it short is as far as I'd go.

Properly made products have to go through testing that simulate hard impact and wear and tear. Cutting/drilling fibers is more likely to result in cracks than in metal. Even if you are a 120lb spinner, it's impossible to guarantee you won't hit a big pothole one day. Just not worth it.

Don't worry, I have no intention of drilling holes in my CF post or reaming out the center or anything that extreme!

I will cut off as much length as possible and use a Ti main bolt. Hopefully this brings it under 150g.

Did it work, I wonder? How successful was the process with the ENVE post?

What about the new Ritchey Superlogic? It has a 25mm setback and I've seen those things come in and under 150g.

Also the Shimano Vibe Carbon seatpost has setback and is very light.

The enve post uses a Ti bolt with the standard rail clamp wedges and a steel one on the oversized (ie carbon) rail wedges.

I would strongly suggest against replacing the steel bolt for Ti in that case. It's smaller diamater and these seat post heads require a really high torque value to prevent slipping. Not worth the 4-5g you might save.

Ours purchased last August, came with the two sets of rail clamps but only the single Ti clamp bolt.
