I mean you can get a full Kashima build for £6500 and at that money it’s a no brainer really. If your swapping out to the EXT then I’d look at the £5500 mode on green, slap that shock in and maybe at some point swap the front fork, cockpit etc. It’ll even come with MT7 brakes and for the money it’s a bargain. At the spec my bikes rocking it’s somewhere between £9k and £10k when you factor in the replacement wheels, better cassette and chain, rental cockpit and Hope brakes.
Having played with the Amflow I would say the amflow has a more “wow” as you ride it due to the power BUT that’s a trap, the novelty wears off, you very rarely use it and the rest of the bikes geo and less burly components so get noticed.
I personally wouldn’t bother with the SC as you’re looking at around £11k for the same spec which is wild. The Levo4 if you consider that in S-works is also £11-12k and personally I think that money is just a massive waste when £8k gets you 95% of the bike.
If you went with the lower spec Amflow and swapped out the fork, shock, wheels, potentially the transmission, cockpit… it’ll be up there with the cost of the top end bike but with parts you want.
The come is headset routing. I hate that. Besides that it’s a fantastic bike and a huge surprise.
