In reply to Removed User:
I have a 2010 Secteur (triple) and am very pleased with it. I've not done triathlons (tho' I may have a go at the sprint distance this year) but I have ridden it on several 100k sportives.
I find it a very comfortable bike for longer rides - the slightly shorter toptube enables a more upright (or less 'stretched out') positioning compared to the Allez. Several friends of mine have the Allez in the same size as my Secteur and I certainly notice the different position.
Downsides:
Mine has Alex rims and cheapo hubs - comparatively heavy and, as others have said, the hubs are not well sealed, so may not last as long as higher quality ones.
Brakes - unbranded (I'm told they're Tektro) are fairly pish! Quality pads improved them somewhat, but I bought some S/H 105s off Ebay which are a whole lot better.
Finally - shifters. My Secteur is equipped with Shimano 2300 groupset. The brake lever/shifter in 2300s has a small thumb trigger on the side of the hoods for shifting to smaller ring. Consequently you can only make such changes with hands on the hoods, not on the drops - might not be great if you're trying to stay aero in a triathlon. I don't know if current bikes still have this system.
As ever, best to have a test ride before parting with your hard-earned!
