Clearance For 700 x 45 = 27.5 x 2.1?

Cyclocross and Gravelbiking (Recreational) This has to be the most physically intense sport ever invented. It's high speed bicycle racing on a short off road course or riding the off pavement rides on gravel like : "Unbound Gravel". We also have a dedicated Racing forum for the Cyclocross Hard Core Racers.

Clearance For 700 x 45 = 27.5 x 2.1?

Hey everyone. I currently am using 700 x 45mm WTB Riddlers on my Giant TCX. Going 650b is always a temptation. Here are my 2 questions:

1. If I can fit a 700x45mm tire does that equal out to a 27.5 2.1 on 27.5 rims fitting in my frame?

2. Those of you that have gone to an around 2.1 650b tire, have you been happy with the investment?

Thanks!

45mm is a few mm larger diameter than 27.5x2.1.

You're probably aware, the TCX clears a 2.0"+ rear. 2.1" front.

Am on 27.5x2.1/2.2 mostly due to the majority of riding I do; heading out to rougher tracks at a more casual pace.

Also have a (mostly) 700x44 setup, but stick to a filetread on that, for road and milder gravel.

The 700c does roll a bit faster, if that's something you prefer.
