For any newer Domane owners-

A) is your left chainstay thicker than your right (drive side) chain stay towards the front where they meet the seat post? It seems my '17 Domane s5 has a duotrap placeholder and that whole chain stay is thicker in comparison to the right chainstay around that section. This also causes the tire clearance on the left chainstay to be a 1-2mm less than the right. I'm assuming this is normal to the frame design but just wanna make sure.

B) which brings me to my next question... what's the widest tire a S5 Domane can take? The clearance near the duotrap doesn't seem like it can take a much wider tire than the 25c.

Any insight appreciated.

Got a response from Trek: Thank you for writing in to Trek. The Domane does use an asymmetrical chain stay, so it is not uncommon to have the tire closer to one side than the other. It is still important to verify that the dropouts are aligned properly and the rear wheel is dished correctly. Your local Trek retailer should have gauges to verify both of these alignments.

So I guess it's on purpose?

I took it to the bike shop and had the dropouts verified and they are in alignment. Keep in mind the "off center" part is only around the Duotrap area of the chainstay. The tire is centered in the dropouts and seatstays, so it doesn't look like your typical off center wheel. Imagine a bulge on one of your chainstays that limits tire clearance on that part of your chainstay. Thats what its like. I only plan on running 28c tires so I think I can get over it. But yeah, its slightly annoying to people OCD like me.

As an update to this, I happened to go to another shop today. 2 2017 Domane S bikes both had the exact same thing. Also an Emonda ALR did as well, although not as bad. I agree it's kind of weird Trek does this.
