Narrative:

After a lengthy delay due to an unrelated maintenance issue; we taxied out and were finally cleared to line up and wait for takeoff. We received a stabilizer and mach trim caution message. I taxied clear of the runway and contacted maintenance control. I wrote up the malfunction and was directed by maintenance to perform a reset procedure. While on the phone with maintenance; we reset circuit breakers as directed. The stabilizer and mach trim caution messages were resolved and we got back in line for takeoff. We ran our checklists as normal and began the takeoff run. At approximately 110 KIAS; I noticed that the v-speeds were no longer set. We continued the takeoff roll and departed normally. The threat in this event was not being made aware that the v-speeds would be removed when we reset the circuit breakers per maintenance control. The error was that while we did complete a before takeoff checklist; we did not notice that the v-speeds had been removed. I was forced to choose between a high-speed abort or taking off without pre-set numbers. We should have been made aware that the speed bugs would drop out when maintenance control walked us through the reset procedure for the stabilizer and mach trim caution message.
