Need new bike for commuting, canal towpaths and trails £600

Yeah found the basic one for £600 but was drawn to the tiagra equipped elite version for £800 2015 model

I have 105's on my Canyon, is it much of a downgrade? Also thinking I could sell the Canyon if the diverge is really that good on the road.

Diverge is a decent bike but it's certainly not the only option cyclocross wise. If by basic you mean Sora then yeah, that is a bit of a step down. It still does the job. I certainly wouldn't suggest getting something from 2015 with Tiagra, that groupset was updated this year and it's a lot better now, pretty comparable to 105.

EDIT: Ah, just realised, your canyon has flat bars. In that case any bike with drops will probably be better on the road, and ignore the advice about shifters, trigger shifters are a lot different to brifters.
 
Here's a pic of my Road bike it's the 2013 model

I like that 2nd pinnacle, accept for the colour but it is a good spec. Still leaning towards the diverge but why no hydraulic disk brakes? Seems strange to be using mechanical on a £800+ bike.
 

If a higher weight is keeping hydro off £800+ bikes, then by that logic we'd only see hydro on low-end bikes where people don't mind the weight as much.

Hydraulic disc brakes do not generally weigh more than mechanical disk brakes. The weight of the fluid and the pistons is usually offset by the lack of a cable-actuated arm on the caliper and the lack of a cable inner, meaning that high-end hydro brakesets often weigh less than the mechanical version.

So do Tour de France cyclists etc use hydraulics now?
 
How are UCI rules at all relevant to what spec you can get on an £800 bike or to how heavy hydraulic components are?

I'm completely baffled as to what your point is?

I don't know the stuff you know so please don't get cocky, it was a straight forward question.
Every body knows that hydraulic disc brakes are way better than caliper brakes so they would be more efficient on a road bike that is capable of going very fast and you need to stop fast.
If they are as light as calipers then are they being used on fast bikes in races now?
 
Ah, apologies - I took it as a sarky rhetorical question rather than an actual question :)

Disc brakes (hydraulic or not) are not in any UCI events yet, but disc brakes are expected to be race-legal in 2017. However, UCI compliance has little to no bearing on end-consumers - many bikes you and I could buy would actually be too light to be allowed in a TdF race!

Better in terms of stopping power maybe, but a lot of pros prefer the amount of modulation you can get with callipers. Aside from cost though, the main disadvantage of discs for both pros and amateurs is probably the increased difficulty of maintenance. Makes quick wheel changes a lot harder, and can be a massive pain to do on your own.
 
I'm sure I heard Carlton Kirby on one of this year's earlier tours say that a lower team as gone with Discs but had to go all disc because they didn't have the budget for both.
