I'm building up a new gravel bike and I'm wondering if there is a website where you can enter geometry numbers and compare fit side-by-side. I would like to get close to my usual road bike, but the new frame has slightly slacker HT and ST angles (more of an "endurance" road frame). The reach measurements are nearly the same, but the effective TT on the new bike is .5 cm longer. I'd like to be able to visualize my fit on the computer so I can get an initial dail-in on stem length, steerer tube spacers, saddle fore/aft, etc.
