Hi there people,

Got a quick question regarding chopping down a seatpost.

Going to look at a Kinesis frame tommorrow whereby the minimum BB to seat rails measurement is 4cm too long for my little legs based on my current setup.

Its a TT frame (KT-415) ans has its own aero/intergrated? seat post.

Is it a simple case of getting this seat post down to allow it to go in further?

Below is an actual picture of the frame

Any advise would be great, don't wanna buy it if it can not be done.

Regarding sizes, its a small, which is bang on my size based on the geometry.

Cheers,

Dru.

    If the post slides up and down in the seat tube and the seat tube has a clamp to hold the seat post at a particular height, then yes you should be able to cut the post to length.

    I'm led to beleive that it has - thanks.

    Is this job that should be done by a LBS or can you literally cut the alloy seat post with a hacksaw?

    Hacksaw if you have the skill. Bearing in mind it has a profiled shape and will require careful clamping in a vice.

    Wrap tape around the post and mark the cut line - and use a new, fine tooth saw blade. Measure twice and cut once! Because of the aero profile you can't use a fork steerer saw guide, but a carpenters mitre-box might help to hold it firm and square. Careful using a vice, you could crush the post.
    Make mine an Italian, with Campagnolo on the side..

    cheers guys for the replies.

    I'm guessing that the LBS might do a better job - what sort of price do you think they could charge - or rather, what would be a reasonable charge for this service?

    To cut a steerer tube, I was quoted £40, I don't think it would be much more than that!!

    you might get it done for free if you go back to the shop you bought it from.

    Here in Australia I'd be unhappy if it cost more than $30 (15 quid)

    You'd be more unhappy if you cacked it up.

    Pay, and let them take the risk for you.

    Its at most a 15 minute job (realistically though, 5 minutes). So £40 for (at best) 15 minutes is £160 per hour labour charge. You were robbed! :roll:

    Agreed - to get a fork steerer on my TT bike cut down recently cost £5 labour at a shop where I have a good relationship with them.

    I did it myself, I couldn't afford £40!! And it turned out perfectly, but I was bricking it beforehand in case I mucked it up!!
