Update
I went back into
Decathlon today and had a good 10 minutes on the Triban SE and non-SE in both 57 and 60.
The non-SE is a tad nicer to ride due to complete SORA groupset (particularly the gear levers themselves). However, I spoke with the staff and they think the Microshift stuff is fine and that I should pocket the £80 difference and take the SE... I think I'm going to kick myself if I don't get the non-SE version though...
As for sizing, he told me that I would be a 60 and he was a different staff member to the one last week. I had the seat at the same height on both bikes and I think I preferred the 57. However, (again), I told the guy that I preferred the 57 and he said I was certainly a 60. He then proceeded to say I would get more overall comfort from a 60 but the 57 would be a faster bike (obviously).
All in all, it was a good experience and it was nice to get a few solid runs on each bike. As it stands, I think I'll be getting the Triban 500 at this point.
But with the sales coming up, I'm certainly go to wait until I get back from my Holiday in September. It's more or less only 30 days away but I'm itching to pull the trigger now.... It's a little sad that I'm looking forward to this bike as much as my holiday.......
