KCNC Ti Pro Lite Seatpost – Why I bought one

Seatposts: Carbon not always the Lightest Option

As some regular readers may already know, I am in the process of building up my new lightweight Viner Maxima RS 4.0 Frameset into a complete bike.

As the frame I have is ultralightweight, it makes sense to try and keep the weight of all the components that I place onto it as low as possible.

However like most amateur cyclists, my main problem is that I do not have an unlimited budget, in fact I would say that I am attempting to do this on a very limited budget. Thus I can’t afford to simply go out and buy all the lightest parts without really thinking about price and so instead I try and make sure that each part that I get offers a good balance between performance, weight and price and thus you can understand that A LOT of research goes into each one:

Seatpost Search
Now I will agree, as far as bike components go, seatposts are not the most exciting. however I would also argue that as they support almost all of your body weight and form part of one of the major contact points on the bike, they have to be one of the most important.

Like most people I began my search filtering out and ignoring all aluminium seatposts as in my mind they were bound to be heavier than even the cheap carbon ones surely?

Well as it turns out, not necessarily so. Most are, but there are some like the KCNC Ti Pro Lite Seatpost that is made from an aluminium alloy called Scandium. Along with titanium bolts and a minimalist saddle fitment system, works out to be every bit as lightweight as many of the best high end carbon posts… and the bonus is that they are MUCH cheaper:

Main Features & Highlights

The KCNC Ti Pro Lite Scandium seatpost is available in a comprehensive array of lengths, diameters and colours that should cater for most road, cyclocross or mountain bike needs and wants:

KCNC Ti Pro Lite Seatpost - Available Colours

Colours

To match my frame I decided on the black version, but there are plenty of options should you wish to match your post to your colour scheme:

  • Black
  • Blue
  • Gold
  • Red
  • Plain Aluminium – not pictured

Sizes

Produced in either 350mm or 400mm lengths, KCNC also supply this post in the following diameters: 27.2mm, 30.9mm, 31.6mm or 34.9mm, so you should be able to find one that matches the requirements of your frame.

Weight

The weight of the unit will obviously vary a little depending on what length and diameter you get, but will also depend on how it is weighed:

To explain what I mean, the image below on the right shows a 27.2 x 350mm KCNC Ti Pro Lite Seatpost at 164g, however it still contains the steel placeholders in the cradle (these keep the fixing bolts in place in the packaging, but are removed once you attach your saddle to it.

Whilst you can also see that the image that German Bike shop r2-bike.com use on the left shows the same size and diameter post at 137.4g. Either way it is still very lightweight.


My Seatpost – weight
On arrival, I quickly unboxed and weighed my 400mm long, 27.2mm diameter one and it came in at 180g (see Image below) and just remember I had not yet removed the two steel placeholder bars from the clamp at the top, so the actual weight is just at little less than this, which once again for a 400mm seatpost is very good.

KCNC Ti Pro Lite Seatpost - Weight

Compared to Carbon Seatposts

Below are some weights and prices of other carbon seatposts that I was also considering:


Shannon Carbon Seatpost– Price Approx: 130 Euros
142 grams (27.2 / 300 mm)
195 grams (31.6 / 370 mm)
A very lightweight carbon seatpost from Shannon, uses the same type of mounting system, but is almost double the cost of the KCNC Scandium Ti Pro Lite Seatpost

ROSE Race Attack SL-160 carbon seatpost– Price Approx: 100 Euros
Length: 350mm
Weight for Ø 27,2 mm is said to be about 160g
Available in Ø 27,2 or 31,6mm
Again, another carbon seatpost, this time from Rose that weighs about the same as the KCNC Ti Pro, but which costs more.

PROCRAFT Seatpost PRC SP2
PROCRAFT Seatpost PRC SP2– Price Approx: 100 Euros
Weight: About 150g, but not sure which size they are referring to, my guess would be the smallest (27.2 x 300mm)

Super lightweight and was very tempting for me, but again just cost that bit much more than the KCNC seatpost and I could only find it from online shops that charged A LOT for delivery (18 Euros) – hidden costs!

Saddleholder / Mounting System

There is no doubting that the very minimalist mounting system or the way of holding the saddle with it’s simple hooks and titanium mounting bolts makes for a very lightweight option.

However I have read that many people experience problems in that it is apparently very finicky to set up and that you may need three hands. Once I have installed it onto my new frame, I will be writing a full review and I will include details on how I found it to be.

I decided that because once correctly setup, I hardly ever need to adjust my saddle, so this inconvenience was worth all the other benefits that this post offers and so went ahead with the purchase:

Price & Where To Buy KCNC Seatposts

Before finalising my choice, I searched most of the online sites out there and I have to say that not many of your usual suspects (wiggle, Evans, etc) stock it.

Where I did find it, I noticed that the price can vary quite a bit (especially on amazon, where I saw it listed for over £200!), but the cheapest option that I discovered was from AllTricks, which is who I opted to buy from:

  • KCNC Seatposts on AllTricks – This is who I bought my seatpost from as AllTricks had it on at the lowest price at the time. They also have a wide selection of other brands. Whilst not that well known in the UK, AllTricks are big brand here in France and is a online bike shop that I highly recommend and which I have used often with nothing but good things to say about them.

I also discovered that Ebay had Buy it Now listings for new KCNC Ti Pro Lite Scandium Seatposts at good prices, however delivery to me here in France was a little too much, but it may be an option for you if you are in the UK/US or other country:


KCNC Ti Pro Lite Seatpost Review

As I mentioned earlier, once I have built up my frame, fitted this KCNC Scandium Seatpost to it and had a chance to use it, I will be writing a full review on it and will update this page in time. Until then, I hope this has helped you a little is supplying you with some of the info and thought processes that I went through whilst researching my options.

Love to get your feedback and opinions of this and other seatposts in the comments section below.

    I have one of these posts on a Giant TCR carbon zero.I cut it down to about 350mm.It’s been on the bike 4 years now.Can’t fault it, size is 27.2 mm and it grips the rails just fine.

    • Thanks for the info and that is good news. I installed mine yesterday and have to say that despite what I have read, it was not really difficult to mount the saddle. However I did do it before attaching the post to the frame, which I think makes it easier.

      • some one

        Hi there, I am reading your posts about your lightweight Viner Maxima RS 4 – & am very interested in this project. I too have great faith in the KCNC posts, (got two older styles ones). I’ve been toying with buying a carbon bike for a while (but just a 2 year warranty on the frames is off putting). However, I will look forward to your posts, as you progress on this… Cheers!

        • So far I have nothing but good things to say about the seat post and the frame. However in my experience the general helpfulness and customer care from Plantet-x is a bit of a lottery. Good sometimes, bad others.
