Just been thinking about this, i have a chain tool so this is not required. All the bolts on my bike are allen head and either 3mm, 4mm, or 5mm. My multi tool (lezyne rap 13) has load sof stuff on it i don't require.
I would ideally like a 3 way allen tool but with 3-5mm keys. DOes anyone do one?
The smaller Topeak ones are dinky and well made.
Crankbros ones are pretty much the best out there
but without any additional unwanted sizes, a multi tool with 3 allen keys and MAYBE a t25?
TBH I'd suggest a Topeak Hexus, and stop carrying your chain tool.
Topeak Mini 9 is the smallest tool I can think of with a T25. Mini 6 is smaller (tiny in fact, quite hard to use on some bolts, because it's so small- not much reach or leverage) but lacks the torq.
But, it's only about 20g lighter then their X-tool, which is much better in use because the tools and handle are just that little bit bigger
Again ditch the dedicated chain tool but got this free when i bought my Spesh about 5 years ago. Nice fitting allen keys so unlikely to chew out the heads which is a the mark of a decent tool IMO. The latest model is slightly different but pretty much the same. Small and has everything I need: (Even nicked the bolt out of one end for a ghetto rear pivot repair on some girls full sus who was semi stranded)

I've got an Alien II which I really rate. Good customer service too, when I lost a bit of it, Topeak sent it out free of charge.
If I was starting again though, I wouldn't bother with a multitool, I'd just carry whatever loose allen keys etc I need. More flexible.
