I think Canyon pricing is about the best value there is in the premium bike market among the major brands. Their pricing has also been pretty consistent.

The few personal data points I have from buying Canyon bikes (road and mtb) indicates that their pricing hasn't really changed much over the last 4 or 5 years at least. There are less discounts available now though. My 2019 Canyon Neuron SL9 Ltd was £4,500 (discounted from £5,000 in a sale). Same bike is now £5,749 but with electronic shifting, which I think would be great as cables on full suss mtbs are a bit of a mess. Or there is a GX AXS option for £4,800, which is what I would probably buy if I was in the market today. Technically it's a level down from my 2019 bike, but it's a newer, electronic groupset.

To put Canyon pricing in perspective, my 2015 Specialized Enduro Expert was also £4,500 with lower spec components. Going back a lot further to 2004, I paid about £3,500 for a similar high-end mtb. My late 90's Ultegra spec road bike with early Cadex carbon frame was around £2,000 built with discounted parts.

Bikes at this level have always been pretty expensive, but now there is a wider range of tier pricing with "halo" specs at the very top end that have nothing you can compare like-for-like in the past. Personally I don't think those "halo" bikes are worth the extra cost over their second tier specs, but the choice is there. It's just the law of diminishing returns, which I think is particularly high with modern road bikes.
