Yes, alpinestars al-mega.
It's a 1992 or 1993 though.
The 1991 didn't have the headtube gusset, it also had different chainstays and dropouts.
The yellow / white one above is a 1991.
I'd guess at 1993 as the 1992 model had a different seatclamp to this one. Possible it's been changed, but the change of finding a later clamp? Unlikely.
The front mech attachment is broken on it.
