Wow a blast from the past!
I've got most of the bits off one of those still, had exactly the same bike for my 14th birthday and Christmas present.
Alivio groupset save the YST headset, very early Gripshift SRT-300 and Taiwan Alloy brake levers. Also fitted out the Flex Stem clone and a 26.2 mm Kalloy seat post.
Frame pretty much came out of the Saracen stable and were really well specced at their price points. Tange Cromo tubeset and fat 1" Tange forks.
Managed to fold the fork blades clean over jumping a concrete paddling pool.
Still use the 1" Zoom cable hanger on my Cinder Cone.
Looks like you upgraded the heavy Black steel bars and moved to Rapidfire shifters at some point, I went down the Tranz-X Purple Zanzibar handlebar route as that was the cheapest alloy bar about. V cool in 1993.
I'd forgotten the name of the bike after I rattle canned it so thanks for the memory.
