    Tallboy Owners.....10mm TA Rear End

    Maybe it has been asked.....maybe not.

    Have a TallboyC that I got back in 2009 when they first released them.

    Been a great bike.

    At 200 lbs. I wish the rear end was a little stiffer. Would love to go with the 142x12, but a new frame is not in the cards at this point.

    So I decided that I will meet in the middle.

    Going to swap out the 5mm QR from my 240s rear hub for 10mm TA w/RWS.

    Question is.......is there going to be a noticable difference in the flex in the rear end?


    Thx
    I crashed hard enough on my Tallboy to break my leg,
    The carbon is way more durable than most people.

    Well, I can't speak from experience with the TB . . . however, I made the same conversion with my AL BlurLT2, and yes it made an immediately noticeable difference in lateral stiffness. Why anyone runs a rear QR anymore is beyond me.

    Also, give a good look at the Hadley thru-bolt. When I made the switch, I originally wanted the DT RWS as well, but after search and reading thread after thread of them failing (they seem to break at the clamp), I went with the Hadley (no moving parts). VERY happy with it. Just remember to carry a 6mm with you.

    RE: Tallboy Owners.....10mm TA Rear End

    I am bout 230lbs, so I flex mu tallboy pretty good. Two of the things I did to tighten up the rear, first I installed a Hadley thru bolt made decent improvement. Then, I checked and torqued all the pivot points to spec. I think this made the biggest difference, these parts wear in and cause flex in my experience. My bike is now awful stout.

    Yeah.....gotta work with what I have....so i am not going to re-lace a new wheel.....I like my 240s.

    If this doesn't give me what I am looking for, then maybe I'll use my Hope's with 10mm BO.

    What do you mean "work with what you have?" If your rear hub can take the 10mm RWS, then it will take the Hadley Thru-bolt as well. They are both 10x135. No need to relace anything . . . . I'm confused (as usual).

    Ahhhh....misunderstanding.....thought you meant to relace a Hadley hub w/ TA.

    I was thinking hub.....

    Yes! That thing is exactly what I have. I think its lighter than the RWS too (if you're into that sort of thing)

    I had the same 240s rear hub and converted it to the 10mm axle. I think it helped and the cost was minimal. Wheel build, spoke tension, rim etc. also add to the flex equation. I thought the 10mm conversion was worth the $80.

    Tallboy Owners.....10mm TA Rear End

    A few yeArs back I found the rear end of my Superlight tightened up considerably when I switch from a QR to CK "Fun Bolts". I agree: QRs are or should be on the way out on mountain bikes.

    I converted the DT350 hub on my TBc to 10mm, and I use the DT RWS. I noticed a definite improvement while grabbing the seat and pushing the rim back and forth. On the trail I didn't notice a significant difference, but I'm 160 lbs and didn't feel a lot of flex anyway. I figure it's an improvement over the standard QR, though, and I've converted all of my mountain bikes to 10x135.

    I didn't found references to Hope 135x10 bolt, but it's also a nice solution to solve rear end flex.
    Also check spoke tension.

    Transition Bikes also sells a cheap 10mm nutted axle, along with a 10mm QR skewer, I ran both when my Hope Pro 2 was converted to 135x10 bolt-through on my old TransAM.

    I converted my King hubs to use a 10mm DT Swiss RWS. Noticeably stiffer with either stout Enve rims or slightly noodly Stan's Crests. Money well spent for me.

    I weigh 175-185 lbs...

    The problem with that nutted axle is that it requires two wrenches to get it on/off . . . not good on the trail. The Hadley only needs on 6mm allen.

    The 10mm QR looks legit, though it suffers from a similar problem as other QRs in that its more difficult to replicate the same tension with each removal from the bike. When you run super tight brake caliper/rotor tolerances, this can make a difference.

    The 10mm QR brings significantly better alignment than the 5mm skewer as well. There's significantly more tension although its not really about that; it sits more precisely in the same place each time. This is why I've switched my hard tail over to the 10mm QR as well. I can tell the Crests are very slightly stiffer, but the brake is always aligned and doesn't irritate me anymore.

    Unless you're breaking out a torque wrench each time, through-bolts will also have variances in compressive clamping force. So will a 15mm or 20mm fork skewer/Maxle/whatever if you think about it. But the difference in clamping force from each instance of wheel removal is pretty minimal here and certainly not enough to compress the frame or wheel by millimeters or something. the diameter and stiffness in bending of the different parts improve alignment to the brake caliper a great deal and keeps you from having to realign every stupid time you take the wheels off. If alignment is your concern the giant skewer option is a valid fix.

    I'm not in a big hurry to go 142mm (not that it's that simple) since the 10mm doesn't leave me desiring any improvement...

    For the OP though, the 10mm skewer tightens up the rear triangle a lot. Definitely worth however much...

    Thanks, got my caps and RWS 10mm today and installed them. Will test it out tomorrow.

    what does the "conversion" entail if I want to use one of these hadleys? Right now I have a DT350 with QR hub.

    Thanks!
    Grit, spit, and a whole lot of duct tape!

    You have to get new 10mm TB/TA end caps and the the Hadley bolt on axle. That's it.

    Through axles are the only way I roll now, I'll never go back to a QR skewer again.
