Bicycle Mechanics - Nitto S65 Seatpost for MTB

Everything I read about this post http://page8.auctions.yahoo.co.jp/jp/auction/h144222058 describes it as being for fixed gear, single speed, track apps. I'm looking at it for my old MTB (1984) to replace a cheap Kalloy. My MTB is set up for commuting and light touring, and I like the saddle set back a bit with the nose tilted slightly upwards. Can anyone tell me whether the pictured post will (or may) meet my needs? That's a pretty good price (about 40 USD) for a slightly used S65 ; they seem to go for about 80-85 USD new.

As always, thanks for reading.

It's a seatpost, unless the one you have now is giving you trouble, a new one wont do anything different. I'm pretty sure the pictured S65 will do just as good of a job at keeping your seat in position as your current kalloy.

Thank you. I didn't know that all seatposts are essentially created equal.

When I go over big bumps the Kalloy will sometimes slip backwards, pushing the nose into my tender parts. And yes, it's on there tight.

It's a single bolt post, meaning it can slip as you Kalloy does. But, I doubt it will, properly tightened. Nitto also makes 2 bolt designs(S83), which will not slip under any circumstances. These run about $100 USD. See the difference here ...http://www16.ocn.ne.jp/~nitto210/newpage1.html

Velo Orange makes a nice one for about $45 though.

The most important thing not mentioned yet is does it have the same diameter as your Kalloy and is it long enough? Some road posts are only around 240mm long and may not be long enough for you so best to measure first.

The S65 is a very nice post, like most Nitto products, and will work great for you if it's the correct length and diameter for your frame.
I've got the Ritchey Logic version of that post (made by Nitto) and it's great. Will not slip. The interface between the clamp and post is as good as a Campagnolo Record.
