The shim is 10cm long, and and at my saddle height there will be approx 12cm of unsupported post below the shim.

Wondering if it would be better for me to cut off approx 10cm of post which would leave me about 2cm of post extending below the shim and give an overall seatpost length of about 270-280mm. Or am I fine leaving the post full length? Since this isn't the WeightWeenies forum I'm not concerned about the weight of a 10cm section of 27.2 ti seatpost:banana:

What would you do? Run the post as is with 12 cm "floating free" within the seat tube below the end of the shim, or cut so there's enough left for adjustments but have more of the post supported.

Then why cut it??
