I had a trail breaker 2 from 1991, 19” which was comically large as my folks wouldn’t listen to my pleas for a 17” (thought I would out grow it)
Lovely frame which took years of abuse
Yes if you remove the long spacer then fit the short one it will all button up nicely, I have a pace mount in the same style which I fitted to a manitou fork with no issues
It’s not a narrower axle you need it’s a different end cap, they had a style that was much thinner and the axle still went through to the drop out the mount sat on the axle and the thinner spacer took up the slack
I spoke to the guy a couple of years ago about this and he wanted £700, told him £450 was more realistic and he never got back to me, glad it found its way home!
I’ll be starting to head up GT in the next few weeks, boring but new trails to be hit due to Buzzards removal…
Will be trying for 7:30pm runs as the nights get lighter
