Update: Time for a new bike; Canyon Ultimate vs Endurace vs BMC...

Thanks so much for the comments.

Yes I hope to ride a Canyon at the show, if possible. 

The Ultimate CF SL 8.0 Disc is probably all the bike I need and well within budget. 

I just can't stop myself thinking about that Mason though. 

The Canyons are very different bikes to something like a Mason, but if I were looking at the Mason I'd also be looking at the Fairlight Strael.

I have a Canyon Endurace SL Disc 8.0.  It's a nice bike, but I'm already looking for a wheel upgrade after only 3 months of ownership!  It's quick and compliant but not a whole lot of "fun".  It also feels a bit heavy on the climbs (even though the stated weight is around 7.5kg).

All things considered, if I wanted a year-round do-it-all bike, and wasn't too bothered about weight, I'd be going for a Fairlight (and in some respects, wish I had!)

Hi, my first post here and I'm in a similar position.

I'm looking for a bike upgrade. A similar spec to the OP - Ultegra, discs etc.

I'm not going to race it so weight isn't of major importance to me. I mainly do fitness rides and sportives.  I want something comfortable and built to last.  

The Canyon Ultimate/Endurace and Mason Resolution/Definition are curently the models I'm most  interested in. I'm attending the bike show at NEC this month for a look at whats on offer. 

I'm wary of ordering a Canyon without having a proper look first. I've only seen older spec models to date.  The Mason can be ridden first, so  a bit less of a risk. I haven't seen the Mason in the flesh, but I'm feeling it could be a good multi-purpose bike for my needs. I also really like the look of it.

Any thoughts on the above bikes and anything else I should consider please?

Budget up to £3.5k. 

Thanks. 

one word...... Bianchi

I recently had the same dilemma. Argon18 Krypton was high on my list (apologies for adding to your list...) But I couldn't try it. I did try a BMC and wasn't wowed either, but probably great bikes of they suit your style. Ended up with a Synapse SE ultegra  and love it...

Of the ones you listed, the Bianchi: bikes should be celeste.  And there's heritage.    I was browsing in a pretty high end bike shop today and what struck me was the number of blancmange bikes they had... lots of bikes, but somehow so little choice. Their most interesting piece was a single Factor.... almost celeste.

Another one for Giant Defy. Mine is fast and comfortable, but has rim brakes as I bought it before discs were a thing on road bikes.  My other road bikes are newer and have discs;  I’d always choose hydro discs now.

Di2 If you get the correct derailleurs, you can have a wide range of gearing options with very little adjustment.  The ancillaries allow visual displays to show gear indicator battery life etc.

Disc brakes, I personally dont know of anyone who once tried out discs for a little while would then want to go back to rim brakes

Bike, unless you're a lightweight a few grams here and there arent going to make huge difference

Personally I'd want one bike with 2/3 sets of wheels/tyre combinations, so that can be ridden on most surfaces. Wide tyre capability- 40mm and eyelets for mudguards, racks etc.

I use Di2 and love it. Luxury, not at all necessary, not even remotely and if you are worried about weight then why drag a battery around?

Hydraulic disk brakes. I use them and love them. Rim brakes are perfectly adequate, but I like my carbon wheels unadorned with a braking surface and I prefer the look of disks on a carbon frame.

After that, and only you know how important such things are to you, it's what physically fits, what you can actually find to buy, budget, brand image, aesthetics of frame design and whether you like the colour. Personally I wouldn't be fussed by ~1Kg weight penalty for the bike I liked over one that maybe technically superior but didn't float my boat as it were.

Yep, that's certainly worth repeating.

You don't need a power outlet near your bike to charge up Di2 - you can use a battery/power pack to do that (it's much easier as you can just leave it charging overnight).

I don't think that the height of the head tube makes this a bike with particularly aggressive geometry.  How about something like this Giant TCR Advanced 1 Disc 2018?

Except for the carbon frame requirement, your list is similar to what I'm looking for as well. I've also heard that the R7000 groupset is good enough although the cassette is heavy, so replace with an R8000 cassette instead to get within grams of the R8000 weight with similar feel but cheaper. Comments on this piece of hearsay is welcome

You don't give a budget or size, but there are sizes 51 and 54 of a di2 cervelo C5 at Sigma Sports for a big old discount

Otherwise, my list looks like this:

• Rose Bikes Team GF Four Disc
• Mason Bokeh 105
• BMC Road Machine 02 Two

• Canyon CF SL disc

• Cube Attain GTC SLT Disc
• Cannondale Synapse Ultegra

Cannondale Synapse 2018/19?

Discs

Light

Eyelets

Looks ok for an endurance bike

Mechanical or Di2 options

New Giant Defy? Typically a lot of bike for the money and I can't remember the last time they weren't right up there with the best review wise.

Personally, I'd go Di2 with hydraalic brakes.. becuase the hoods are so much nicer (and lighter). But I get the simplicity of not having to worry about messing about with sockets.
