GT Tempest

I could be wrong but I think year 2000 or 2001. I think the two tone colour scheme is later than 1998/1999 but the "X" brace between the seat stays and drop out design earlier than 2002.

It's definitely a 1998. I had two of them. Both got stolen.

1999 in Team Colour. The 98 GT race team Zaskars/Xizangs were that colour but for some reason the 99 'Team' models of those were just plain white. The Tempest and Outpost Trail both came in this colour in 99 (I have both !).

This is a 98.

This is a 98, in 99 it was blue, white with a black divide. It was blue at the rear of the frame too in 99.

Trying to work out the exact year, it was between 1998-2000 I believe, the frame serial number is MA4900421, any ideas?

Hi
I have the exact same bike. Got it new in -98. And I got inspired to do the same gear upgrade!
Is it a hollowtech2 BSA 68/73mm bottombracket?

Ah excellent, go for it, I ride mine weekly and love it. Send me some pictures when it's done.

That's correct, I've got a SM-BB52 bottom bracket fitted:
