Does anyone know when Trek will be releasing their new FX 2015 models? I was looking for a "Official Trek FX Thread" but couldn't find one to post this in.

I think there are a couple of them up on their site now. The Duo Trap models.

Assuming you're asking about availability in the U.S. market, the following 2015 models are currently available: 7.2, 7.2 Disc, 7.2 WSD, 7.3 WSD, 7.4 Disc, 7.4 WSD, & 7.5 WSD.

I just picked up a Trek FX 7.2 2015 model at Scheels today. Lucky as all get out... 3 days ago I bought a 17.5 inch frame, was too small. I took it back and asked to exchange it for a 20 inch. They didn't have any out, he went back to look if they had any, and came back out with the 2015 version. He said they just arrived ... plus, for some reason, it is $50 cheaper than the 2014 version. Rode it for 12 miles tonight and loved it.

So... to answer your question, they're out there

I got my 7.2 FX WSD on July 4 and my fiancé got his 7.4 FX disc last Saturday.

Do you know if there will be a 7.0 FX in the US market sometime soon? I keep seeing this model online: Trek 7.0 FX 2015 Hybrid Bike | Evans Cycles, which makes me very hesitant to purchase the 2014 model.

I really couldn't say for sure. My guess would be that they will all be available by the end of August at the latest (i.e. after the US "Trek World" retailer show), but there's no guarantee on the timing of each model's release.

I already picked up my 2015 7.4FX disc. I like the ride, haven't found the sweet spot on the seat yet but excellent bike. I got the bluetooth/ant + duotrap s sensor and I was told they are releasing a compatible phone app called Blendr for it but I haven't found any news or additional info when it will be released. Below is a picture of it as it is still not on the Trek website yet.

What does the colour look like in real life?

From photo's it looks inoffensive, but a bit bland.

It is also a bike that I will be trying in a few months time, as I am seriously considering getting it.

It's a flat grey? Color mostly. White lettering and almost a neon green accent. Wasn't crazy of it first but we got acquainted relativity quickly. I love this bike be careful because with this type of money you could get yourself into entry level road bikes. Do your homework and make sure you get what suits your riding style!

The 2015 7.5 is a Chrystal White, starting to be more available now... Ended up going with a 2014.

The website seems a little screwey. The 2015 7.3 FX is under the Road > Fitness section while all of the other FX bikes (including the 2015 7.3 WSD) are under the Town > Fitness section.

Looks like a signifigant improvement in aesthetics over the 2014 7.3 FX. (Though to each his own.) I like the matte black finish and the internally routed cables.
