• Hey all,

    I have a thomson elite seatpost, and an ergon sf evo saddle…
    The clamp of the seatpost is clamping closed on the front, but not on the rear of clamp, where there are a few mm of space between the rail and the clamp above, and below. Meaning that the saddle can flex at the rear and if you push on it you can see, from the rear, the rails move down towards the lower plate of the clamp.
    Any idea what might be going on?
    All clamp pieces are facing the right direction (front)… and as far as I am aware this was not happening on my previous seatpost (not a thomson elite). I don’t have another saddle that I can test to see if it’s the rails or the seatpost, but as the rails seem like they are centred in the clamp - it makes me think it’s the seatpost clamp that for some reason wants to tension at the front more than the rear, even if I tighten the front and rear bolts in small increments..
    I can’t understand why this might be happening. Any ideas anyone?
    I can buy a new clamp on the web, or try it with a different saddle… but wanted to ask if anyone has ever seen this before? Can’t find anything online.

    Thank you very much.
