Makes sense but I mostly road cycle now anyway, but on a 15 year old mountain bike. I think I’ll be even more keen with a more suitable bike. What are the most stark differences between an mtb and rb that may put me off?
Well that Cube I have is the first road bike I've owned since 5 gears with downtube shifters were the norm, and I bought it just overa month ago to switch from the Boardman hybrid I had been riding.
Not
quite the same as a mountain bike, but not too far off, particularly since it had front suspension.
The first thing I noticed was how twitchy the road bike felt. The first time I went out on it, I wondered if I was going to be able to cope. But the 2nd time was much better, and I was past the twitchy feeling within 4-5 rides. That now translates to it being much more responsive
The riding position is a bit different - I still don't feel very comfortable in the drops for long, but I think most road cyclists spend most of their time on the hoods, so that doesn't bother me. On the hoods, the position isn't different enough to be uncomfortable for me, but it is possible you would find it so.
The ride will also be firmer, even relatively wide tyres on a road bike will be narrower than you have on a mountain bike, and you need to have them inflated a bit harder to avoid pinch flats. Though again, having gone from 38mm at 80psi on my hybrid to 28mm at 100psi on my road bike, the difference wasn't really all
that big. And having just switched to tubeless on the road bike, I'll be dropping the pressure back to 80-85psi.
And then gearing. The lowest any of your examples have is 34/34, while your mountain bike probably has a lower bottom gear than that. Although the road bike will be lighter, if you have hills around where you are regularly using the lower gears on your mountain bike, you may find it hard at first. You almost certainly want a compact (50/34) chainset, unless there are really no significant hills where you ride, and an 11-32 or 11-34 cassette. But I think all your example bikes come with that.
Yep, been on the lookout second hand lately but nothing that takes my fancy, it’s one of those where I think how long do I leave it? I want to get into it now so feel I need to make the jump.
Yes, there is always going to be the issue of timing, and do you wait for something better. You really have to make a decision and just go for it at some point - then stop looking at others once you have decided, to avoid regretting your decision if something better comes along.
