Bike parts unfortunately happen to break, if you don't want to ever have trouble with your bike then better not ride it :)


Sure... but judging from your frame and parts why really did you choose this seatpost and saddle?

Hmm the frame might not be the lightest but it has some good parts on it - ITM The Stem, Deda 215 bars, Nokon cables, KCNC skewers etc.

I been using the Endurance saddle for months so decided to leave it on the cross/training bike (other bike has a Phoenix), and about the seatpost, i wanted to upgrade it as the original one was a Ritchey, not very light...

The KCNC seatpost was an option as it is light and cheaper than the AX, but went for the Daedalus instead as it has a layback, and the frame feels a bit too short (my other frame has a slightly longer top tube and i use a 135mm stem)...

Ouch. Not just any broken part but that's several hundred euros broken.

I looked at getting this post but worried about breakages which seem more common than in other posts. Maybe this is not the case but it's clearly not as strong as other posts.

But that is weightweenieism for you, sometimes you get expensive problems :cry:

One reason I only ride parts that I can replace. My lightest ebay saddle weighs 125 grams...a measly 50 grams difference and costs much less.

It's gotta be pretty tricky to build that "head " to the post in that shape. Looks as if this one may just have been a shade light on material up there. When the envelope is pushed, you periodically get to see the limit.
I'd happily use an AX pillar. If they ever build one that can fit over the addict isp, I'll buy it!

what he said

"I would never put such a delicate piece of equipment on a bike that's treated not particularly in a silky smooth fashion"

does seat post weight even matter in a cross race and why would you risk it hurting the man parts?

just use your brain to save your man parts bro! glad u made the post so everyone can consider the limits they want to push on delicate parts (those on the bike, and those on their body)

I know, well, happens, but not sure if should happen...

I've ridden two 12hrs solo XC races (with a different bike) using a FRM carbon post (160g if i remember right) and had no problems at all...

The worst of that is the thing that could happen with your body, that´s a very bad part to break

I talked with Madcow about this seatpost for MTBs and he told me that although it says MTB, AX specifically advises against off road use for the post.

Why would they put MTB? Your guess is as good as anyones.

That being said I have used the KCNC post for real cyclocross (dismounts and remounts not just off road riding) and have had no issues.

Glad to hear you are OK!

Actually, it says right on the back of the seatpost:

[i]Max. 85kg
Road/MTB


Max 85kg and MTB are contradictory.

I saw that in the photo and definately not the stem (or post/saddle) I would use for the abuse of cx...

between the bunny hopping, mounts/dismounts etc...

just installed mine , its scary light and thin
when looking at your picture u can see the crack goes threu the dimpled letters,that is/could be a weak(er) point
regardles of this case,85kg for road is not the same as 85kg mtb or cx in my book,but i dont to claime to be right
if u would get a new one for free i would still use a other one
