The way I look at it, If you like the way it rides and you want to ride it... upgrade it! This is the Cdale that was all black right? Someone else in C&V or mechanics might know about adding more cogs. I only know you cant cold set the rear triangle (because its aluminum) so that limits the size of hub. Im going to go out on a limb here and say you might be able to squeeze a 130 in there but I'm not sure. I would get a second opinion on that. Good luck! Hope this helps.
