Bolt, maybe, in small piece of office equipment (8)
I believe the answer is:
sprinter
'bolt maybe' is the definition.
(Usain Bolt)
'small piece of office equipment' is the wordplay.
'small' becomes 's' (abbreviation - e.g. clothes size).
'piece of office equipment' becomes 'printer'.
's'+'printer'='SPRINTER'
'in' is the link.
(Other definitions for sprinter that I've seen before include "Athlete" , "Fast runner" , "one promising a fast run?" , "Short-distance runner" , "one running" .)
