What are your thoughts on the N9 which comes with 150mm of travel up front. Great review...Thank you.

[Scottslookingabout]

surprised you liked the stock that the stock seat?

Would love to buy it as frame and suspension only.

The parts it comes with as a built bike ain't bad but I think it could be more practical, I'd definitely cut corners on the drivetrain and put AdventX groupset there, a Rockshox Pike select+ for the fork then splurge on a better wheelset, maybe a 170mm crank too.

As for the dropper post and stem, meh.. it can be anything.

Would be a budget consience option to increase the fork it came with to 150.

I went wolftooth too, oneup guide and bash, edc lite, ergon saddle, I9 Hydras, fox guard, fox lsc dial. Ride wrapped out the box.

The stock stem is so ugly 😂 glad I'm not the only one. That jump trail looks super fun

I do not remember the full upgrades you made on this bike, but when speaking about fork you mentioned Performance Elite vs Kashima. Are you telling us that you upgraded from Elite to Kashima? If that is the case - what a waste of money for the same damper and a tiny bit of weight saving if at all.
All in all, the things you 'hate' about the bike were mostly esthetic (stem). Calling it hate is, imho, not correct term. If you'd buy any other brand bike with other parts - there would be still parts which would not suit your taste or length (crank).

I do not know, maybe it's me, but almost all videos I see from other side of the pond talk so much about UPGRADES to the bikes. Reddit is also full of threads about it, people buy a new bike and are like: what should I upgrade on it. Nothing bro, just go out and shred it for 2000 - 3000km then see if something needs upgrading or changing to same new.

Changing to less weight wheels is of course noticeable, but imho, only if 1-2k is burning your pockets - it's not an investment a regular MTB guy needs. Is it a nice to have? Definitely.

impossible to order this bike in France, too bad!

[EntertainmentByKV]

+i think that the jeffsy core 3 from YT is a better option for a little bit more money (3k) cause you get a carbon frame... not that aluminium is bad but

[CJGrand]

I'm sorry, but weight focus on a mtb is just ridiculous. Put on the bike what you like, but stop obsessing on the weight of parts. It just all creators new and old constantly blah, blah, blah about the weight of parts/bikes.

[chillsteplife]

I thought you loved this bike. You made so many upgrades to the bike. What happened?
