A comment from Altimis Nuel in this entry asked if I can provide photos of the American Classic 420 Aero 3 rim profile with the tires on. He wrote:
Mark A, I need your help please.
I want to ask a pic of vertical/frontal of the American Classic 420 aero 3. I want to take a look if tire/rim width is perfectly hooked with no "mushroom/muffin" bobhead effect or not.
Planned to buy one but I can't find anyone provide me a good close look of tire/rim section.
Thanks in advanced, your bike is really beautiful :)
Dear Altimis Nuel,
I have no knowledge of posting photos on the comments section of my blogs. What I can do instead is create a new one for the sake of your inquiry. I'm pretty sure you are not the only one who is wondering this matter. Like you, I do make extensive research about a product before making any big purchase.
The 420 Aero 3 is the 2016 model which is wider than the previous iteration. The sections below shows the difference between the 2016 model to the previous model.
Now that the rim profile difference is laid out, it is evident that the 2016 model is 3mm wider and a rounder. The bead hooks are noticeably slimmer. You'd wonder why how they'll catch the tire beads.
The tires mounted on my bike are Continental Grand Prix 4000 S II 700 x 25c. The following photos show the overall profile of the rim and tire together.
The tires slightly extends outward about 2-3mm. This is good for protecting your rims. Looking from far away, you'd think that they are flush.
From this angle, you'd see less rubber sticking out. You might have zero mushroom bobhead if you use 23c tires.
I hope this post will help you decide on picking up a pair of 420's. I would recommend this wheelset, having used it for some time now. These wheels are the lightest all aluminum set I can get locally. If not for the big price difference among other all aluminum rims here, the 420 Aero 3 would have won the best value for me. Fulcrum Racing Quattro LG's are sold here for about half the price of the 420 Aero 3. If you have more questions, hit me up in the comments section.
Thank you.
Mark A
