Hey guys, still kinda new here so not sure if this is the right forum so apologies in advance if so!

So title says it all. Im putting 26" or 650c on a 48 cm road bike and was wondering if, since the bike is gonna be lower, i'm gonna have to switch out the crank arms as well. Any thoughts?

Also, am i gonna have to get my gears re-tensioned for the new set up? I feel like i would but im not sure. Please let me know!

Thanks!
