Found this picture of a TCX with 27.5 tires, something which I am inspired to imitate:
I was interested in the Giant TCX Line for a while and I've started to pay more attention to it now that they have both a lower end Alloy and Carbon model that I like. My number one interest in the bike is the large tire clearance given it's cyclocross nature; my number two interest is the 60mm BB drop which means less pedal strikes with my flat pedals (yes I run flats, fight me).
From looking around the web I've seen some anecdotal references saying that it can fit a 45-50c tire front and rear, however I've only heard of this for the alloy model and not the carbon. What I want to know is does the carbon TCX has more or less tire clearance than the alloy? I really want the carbon model as it'll be my first full carbon bike, however if it has less clearance than the alloy TCX I might have to choose that or look at other bike options.
This is true, however there are few stores near me and they don't have them in stock. What I want is to hear from people who may have had experience running wide tires in their TCX, specifically the carbon model.
Not sure I can go to a bike shop and ask them if they can put 45c tires on the TCX to see how they fit...

Any bike shop worth anything would know what size tires that should fit their bikes. Good luck on some replies and finding the right bike for you.
My 2015 TCX (alloy) easily swallows a 45 up front. The rear is a little tighter but it does fit. I had them mounted on the stock rims.
Right now, I'm using HED Belgium+ rims and 700 x 40 Maxxis Ramblers - not as wide but SO much better running tubeless with the +rims than the stock set up. Plenty of room. Good luck.

Thanks. With the 45c's in the rear did you know how many mm's on each side there was? Also was it QR or thru-axle?
My Rambler measures 40.5 at 35psi. I have just over 8mm gap on each side of the tire. That puts us near 56mm overall. It seemed tighter that that with the old 45's mounted. I don't have them anymore to see what size they were inflated on the rim.
When trying to fit big tires on a bike that is not designed for them, you need to be careful of pictures on the internet. They may "fit" enough to take a picture, but you can't really ride on them. I learned this back before 650b/27.5 mountain bikes existed so I was looking for a 26" frame and fork to do a conversion. I bought a Manitou R7 fork based off of pictures on the internet. When riding the tire would rub the crown on big hits and rub the arch during hard cornering. I personally have my doubts that the pic you posted is a rideable bike with 2.0 tires, unless they aren't true 2.0 in size.
That's true. That's also why I'm asking if others have attempted things like this. The fork is definitely not a problem area, however the rear is where I'd question clearance. From other sources, people said when the TCX switched to a 142mm thru-axle that rear clearance was increased by a bit so that's why I asked about the rear dropouts.
