Early Bontrager race lites are not corrected for the fork i saw in pictures. Problem is not even taste: it will not handle well. If you want a hardtail w/100mm of suspension dont build an early 90s classic frame. That is a very small frame, suited for 1m 65cm at max.
The other day i was watching on youtube an early Bontrager race light build. The shop was lovely and i could feel the love from the owner/ mechanic for the frame. The list of parts he chose for the build had great high end parts like Ringle hubs and Ritchey cranks but other than the salsa...
Check the bb height against Ibis specs. It's all about that number. 420 is ok. I would look for 430 but 420 could be fine.
Stem is too short. They used 120/135/150 mm. A 71 degr. head angle w that short stem will make the front too nervous. A longer stem will calm things down.
I believe that generation, built w/ Prestige, is the lightest Mojo frame. My favourite color as well. I would buy another frame just for this color, and build it all NOS shimano m 737.
