General: Hub spacing/frame spacing

so i just bought a complete Vivalo bike. the front spacing is: 100mm /w 9mm axle
the rear spacing is: 110mm /w 8mm axle
the wheelset that came with it is a dura-ace 7600 hub set: front: 100mm
rear: 120mm or alittle less
i dont know if the original owner knew his rear spacing was 110mm and he was using 120mm and stretching out the dropouts. im worried if this is harmful to the frame. if so, could i adjust the spacing on the rear hub to make it 110mm? if you can, how is it done? i tried to loosen the bolts on the axle (not the end bolts) but they were stuck and i wasnt sure if i just needed more force to loosen the bolts or what, but i just didnt want to mess anything up that i wasnt aware of. any help/opinions would be greatly appreciated, thanks!

what is the frame made of?

where can you get the conversion kit?

thanks

steel is easily malleable. your lbs should be able to do it for not to much money. park makes very cool tools that do this, but they are kind of expensive.

Or just spread the drops when you install your wheel and call it good. It will not hurt a steel frame at all.

This sounds pretty typical. Someone buying something and not knowing anything about it. Good thing you caught it. Have you tried to put a 120 in there?

That sounds so dirty.....
