2025 Mathew’s Bows

[Jake Larsen]

I was asking it rhetorically.


You adjust it it by moving, and the point of everything I have said is I'm not certain this system as it is will provide enough movement as it is.


You don't need a laser to measure it, just a straight edge.

My point is simple. If you start a bow build/arrow tune with a properly set up bow and a properly spined arrow, you won’t need to move the cams very much at all. You don’t need massive amounts of movements if you’ve done everything else correctly.

Starting with parallel cams is quite important in this process.

My point is after tuning a good number of Mathews with the Top Hat system, and the range some of them have needed to shift from how they came from factory, I'm wondering if this system has enough adjustment without needing to change the one top hat some. Wouldn't be drastic, and probably not common, but no more change in cam lean that I saw with the 2 I played with, I think it might need to be done some.

It might be they really have limb deflection dialed in now, and it's extremely consistent. Putting 2 limbs together to make one you can probably get the tolerances tighter, if they are doing that. Might be they are just grabbing individual limbs out of a barrel, and you could have two weaker limbs paired up and two stiffer limbs, kinda stacking tolerances.

I suppose it could happen…i guess I’m willing to take the plunge based on Mathew’s QC in the past. I would think that would become a warranty issue if so.

I mean, I was pleased with how easy it was to pull the axle. So changing yokes aren't really anymore complicated, just will need to reference where the axle position was, but the donut placement tends to slightly change cam lean anyways.

I feel really certain that a shop should be able to check cam lean, change the TH if necessary (doubtful, but maybe a few) and the customer can take it home and tune it.

I wrote that review; my mod screws were blue loctite in and not loose. It took heat and a LH drill bit to get out.

The cable being cut is the issue that should have been caught in design/engineering if that bow couldn't stay on track at max DL and the cams shimmed over.

The rx8u is at the 30.25" position right now which is the bottom of the longest mod. I was thinking about twisting cables to go back to the top of the 30" mod for more speed, but maybe that isn't such a great idea.
