Convert QR Skewer freehub to Thru Bolt?

I have a rear wheel with an FH-HG50 quick release freehub. I'm building up an old mtb with horizontal dropouts to run as a single speed, so I won't be using a derailleur or chain tensioner and was wondering whether A) a thru bolt would be less likely to cause the wheel to get pulled under pressure and B) whether it's even possible to change the axle on this hub.

What do you good folks think?



(not my pic, but this is the same hub)

10 by 1 mm solid steel axle fixed in frame with hex head nuts , can replace the hollow QR axle..
Shimano uses 10x1 threaded cones..
then you must bring , or borrow a 15mm wrench to fix a flat tire..

NB not what is now selling as through axle .. 'TA'

but why not just get a hub for single speed.. say building a wheel around a freewheel hub..
symmetrically spoke angled, centered under the rim ;; with a screw on freewheel ..

There are wider hubs that can build a stronger wheel ..
specifically for single speed MTB.
without the dish compromises to make room for that stack of gear cogs
(cassette or freewheel)

That's a nice hub. Whether or not it slips in the dropouts has more to do with the locknut faces than the method of fixing it to the frame, but the axle is easy to swap. The original steel locknuts on that hub had deep, sharp serrations.

Great considerations! Of course, the ideal would be to have a dedicated 135-spaced flip flop 26er wheel, but accounting for time, skill, patience, space to keep it and of course money, I would think that for now switching the axle should be good enough. I've seen garages where people have wheels just literally hanging around so they can switch whenever they get the urge. One day

My commuter has rear locknuts, so I always have a 15mm combo wrench on me and I'm used to torquing them. Maybe it's because of how thin they are, but I just can't help feeling that qr skewers can't be tightened as much as nuts on thru axles without eventually snapping or failing. But maybe I'm wrong, in which case I'll keep them as qr's.

Yes, they definitely have some bite.


Thanks for the input, guys!

I have used a common freewheel hub, (not flipflop)

moved , equalizing, right side spacer width, to the left side of the hub axle.

to center the hub on the axle , de dished the spoke tensions

and my cost was just the single cog freewheel.


( Here, not flat, and I , no longer young , I've re adopted IGH for at least 3 speeds )

That sounds like a great idea. I think I actually have a 26er freewheel at my parents' place. I'm pretty sure it's also a qr, but I wanna try what you said anyway, even if it's just for the learning experience. THANK YOU!

I've switched hubs to nutted axles. It's no harder than taking it apart to re-pack the bearings. I use "track nuts" which have a built in floating serrated washer.
