Hi All!

I just picked up a Ciocc Alelle frame with 126mm rear spacing. I would like to run semi modern (brifters) groupset and hence was wondering if I should have the frame cold set? I just picked up a mid/late 90's campy Veloce groupset with wheels as well. The rear hub is 130mm. When I took off 2mm spacer on non drive side, the hub is able to slide in easily. The LBS close to home can cold set it for $30 and adjust the drops. The owner of the shop did mention that he adjusts it using his hands and uses the tools to measure and correct any adjustments. Wondering if I should leave the bike as is and slide the hub without the 2mm space which sets it at 128mm? Appreciate any feedback and or pointers. Thanks
