Cyclocross Advice

Hello All, 

I'd be very grateful for some advice. I'm looking at getting into cyclocross with plans of doing some CX sportives and probably some racing as well so need a bike that can do everything. My budget is around the £2,000 mark but can go over if the bike is worth it. In terms of frame, I would imagine aluminium would be the best to go for as I can beat it around a bit more than carbon and I'm apprehensive of falling off. I do own a carbon-framed road bike so know the difference carbon makes - if any of you think carbon would be a better option then please let me know. In terms of groupset, I really like the idea of SRAM's new 1x but would perhaps need to play around with ratios a little bit to tune into my riding. I would be willing to consider Shimano as well and I have Shimano on my road bikes. Also do thru-axles make a big difference or are standard QR's still ok?

Specialized Crux E5 X1

The best bike at the moment looks like the Specialized Crux E5 X1

It has a SRAM Rival 1 groupset and is aluminium and looks pretty neat. It does use QR skewers though. 

Fuji Cross

This also looks like a good bike, but frame wise probably not as good the Specialized. It has a Force CX1 groupset which is an upgrade. However, I've heard bad reviews of Fuji's in-house brand, Oval's wheels.

Norco Threshold

Stepping up to a carbon frame now, but it's 'mid-modulus', so is aluminium better here? This does use thru-axles though and spec is pretty good.

Trek Boone

I own a Trek road bike and know they are very good, so perhaps the Trek is the best option with the IsoSpeed decoupler as a sort-of suspension and a 600-series OCLV carbon frame. This is over-budget though - do I need this as a first CX bike or is it overkill? I would also look at upgrading the FSA chainset and wheels here again as the Bontrager wheels that came stock on my road bike are shocking. It is also a Shimano groupset. Trek is also one of the best brands when it comes to warranties.

Trek also do some cantilever options in both their Boone and aluminium Crockett range - any thoughts?

I'd be really grateful for some advice and would be interested to hear what you think which bike would be most suitable. Thanks in advance.
