Just bought myself a new C'dale Synapse Alloy Disc 105 this week and want to change the seatpost (currently a C3) for something a tad lighter. I can source the C'dale C2 for £45 but was wondering whether the 350mm post length will fit inside the seat tube or whether it will need to be cut down. The current post is 300mm long and I'm struggling to find anything that has the stupid 25.4mm diameter other than the C'dale C2 and Thomson Elite (which I'm not keen on).

Any ideas?

    350MM Post will fit the seat tube fine, FSA do 25.4mm posts , they are used on most of the new higher end Evo Sixs and Synapses. Be careful though there are a lot of Fake Carbon FSA items on E Bay.

    Thanks for the info. Tim. Struggling to find anywhere that sells 25.4mm FSA seatposts. Found one place, here, which will have them in stock from mid-September, but no prices:

    If you know of anywhere else I'd be very grateful for links.

    Thanks also for the heads-up about ebay and FSA; probably wouldn't have used them anyway but a warning is always good.

    Hiya,

    I have a Di2 compatible 300m C2 seatpost that was fitted to my Synapse - incorrectly!

    It is surplus to requirements as I had to buy a 350mm one for my leg length, so has never been ridden on, although admittedly it has been fitted of course.

    PM me if you are interested - can easily send pics etc etc.

    My pleasure Ruth, hope it serves you well, and good luck with your stem search - don't pay too much for one though!
