It seems common to have suspension pivot fasteners in such a tight spot that the normal torque wrenches just dont fit (head too wide and 3/8" drive bits too long). See pic below. My Ibis was like this, my new Giga is like this and a number of other FS bikes i've had.

Taking these apart and servicing is tedious with just L allen keys. Even ball drivers dont generally have enough angle to spin them. One answer might be using a low profile ratcheting wrench just for hex bits, then use a low profile torque only wrench (such as the Effeta Mariposa) to torque them. But that wrench is limited in its peak torque. A combo compact hex bit ratcheting torque wrench that goes up to 20+nm would be ideal

Any suggestions on such a unique niche tool? What does the factory or shop assemblers use here? Or are they just hand cranking down on L keys Gutentite style?

You could almost certainly get a bit-style torque wrench in there, but it's going to be tight on the return angle of the wrench.

Wera and Topeak both make a 1/4" bit-style wrench.

I found a few interesting items. a Syntace 1-25nm tool, a Wera 1-25nm tool and the Topeak D-Tork 1-20. The Syntace seems the bargain of the bunch at around $130 and worth a shot.

I have the Pro Bike Tool 1/4 inch torque wrench. Goes up to 20 NM, fits in that space just fine on my Spectral and costs like $70.

That one didn't have 1/4 hex drive--thats the key for having the shortest possible clearance in the tighter spots. The Topeak is the clearance king but the others a just a few mm behind. With a 1/4 square drive, the clearance becomes really long since you cannot recess a simple bit in the head.

I got a set of these gearwrench low-profile sockets - GEARWRENCH 9 Pc. 1/4" Drive Stubby Hex Bit Metric Driver Socket Set - 81160 - - Amazon.com. They sell them all over. Gets my 1/4" click-type wrench into a lot of tight spaces

The Silca Ti torque wrench set is really nice and comes with a nifty tool roll. It has all sorts of configurations for tight clearances. I got mine for approx. $100.00 - on Amazon - you won't be disappointed - and has lifetime guarantee.

That's a nice T-set, but I doubt that T-wrench will fit inside the OP's spot there. And, the Silica torque doesn't go high enough for these pivots.

I would just use a 1/4 drive low profile hex bit, a universal joint and an extension. You'll probably have a bit more than a ten degree deflection angle, I would think (but not positive) you would be under-torquing when the wrench reads the said value. So just add some blue loctite to the threads and go ride. It's not like your installing new camshafts in a Ferrari.

just slap a bit in there and crank on it with an extension
