I've never used more than one set of struts for a Mark's rack, but if
you look at the staff bikes, you'll see several with a hub area strut:

All the Staff Bikes that have a Mark's Rack installed use two pairs of struts, both running to the mid fork braze on.  I started using that set-up on my brevet bike as the diving board piece began to sag on my Mark's Rack.  It's the stronger setup if you are running some load on the Marks Rack on bumpy roads.

No, if you look at Vince's, Grant's, and Mark's QB, you'll see a hub area strut.

Not certain, but I think that GP's Atlantis and Mark's QB have hub area struts because they have Platracks installed on the Mark's racks; Vince's rack looks like a Top Rack installed on the front, maybe with a Mark's rack-style diving board too. On a quick look, I don't see any bare Mark's Racks with hub struts.

Oops!  My bad.  They've added a lot of Staff Bikes.  My apologies.  

I had been referring to Miesha, Brian and Keven.  All three of those have a Mark's Rack and have a second set of struts going to the mid-fork braze on.  Since then I see two more Marks rack setups without any secondary struts:  Grant's Homer and Elizabeth's Hillborne.  

There still are no Mark's Racks running a second set of struts to the hub area, though.  

Vince isn't running a Mark's rack.  That Looks like an R14 to me (much larger platform), running struts to the hub area. 
Grant's Atlantis doesn't run a Mark's Rack either.  That's a Mini Front, with a Platrack, which runs struts to the hub area
Grant's Alba-Homer is running a Mark's Rack with no secondary struts at all
Mark's Quickbeam is not running a Mark's Rack.  It's running a Nitto Mini Front with a Platrack.  The Platrack runs struts to the hub area

Struts to the hub area is a common and smart way to add support to a rack.  The problem with longer struts is they are way easier to bang on something and bend, and once bent they buckle so easily that they no longer add a ton of support.  Some list members have taken their long Platrack Struts and cut them way down and connected them to the midfork braze-on as well, which looks really slick.

Once the Hub Area Rack comes out there will be several new combination shown off, I'm sure.  I'm heading to the hardware store now to look for 7mm aluminum rod.  

Keep bolting those racks together in creative ways.

Hi Matt, just throwing out the example of long Nitto struts with an M-18 front rack, attached to the dropout lugs on my old Raleigh.  

I've since added some Honjo full fenders, and they share the lug fitting with no troubles.  

With the Honjos, I've also managed to use the front diving board bolt as an additional fender attachment, giving me a rock-solid 3-point attachment on my front fender.

Before I finalize this installation by cutting the struts to proper length, I'd like your opinion.   I ask, because a long Nitto strut attached to the front hub area seems like such an obvious improvement in overall strength, yet I do not believe I've ever seen it or read about it before.  Am I missing something, or is this a good idea?
