Parr8hed Posted May 21, 2019 Share #1 Posted May 21, 2019 Stupid bike is all back together. The brake rotor is hitting the caliper mount. What he hell. Am I missing something? Fits well in the drop outs. Cassette lines up with derailleur. Just the stupid brake rotor. Link to comment Share on other sites More sharing options...

maddmaxx ★ Posted May 21, 2019 Share #3 Posted May 21, 2019 Need pics of the brake rotor hub as well...........at least I do. Maybe someone else can comment. I've forgotten: Is this an MTB frame, a Cross frame, approximate year. What's the source of the wheel? 6 bolt rotor or centerlok? Adapters or spacers?

12string Posted May 21, 2019 Share #4 Posted May 21, 2019 Look, do you want the brakes to stop you, or not? The frame is stopping the wheel, success! 1 1 Link to comment Share on other sites More sharing options...

I'd ask one of the current wheel builders but I believe there may be a conflict on the standard wheel spacing for 29'ers with some at 135mm old school MTB and some at 142mm with or without thru axles. I'm tapped out on this one. Was it difficult to set the wheel in the frame, width wise? Does it look like there is extra axle on the non drive side?

ChrisL Posted May 21, 2019 Share #7 Posted May 21, 2019 That is a tough one... I’m guessing that if the hub fits in the drop out it’s the correct sized hub. So my thought is 1). Is the rotor properly installed centered and straight/not bent. 2). Is the hub properly aligned in the drop outs? I have seen drop outs not properly aligned so I had to “eyeball” the hub when installing wheel as if I had it in both drop outs the wheel was off.

ChrisL Posted May 21, 2019 Share #8 Posted May 21, 2019 One other thought... some bikes are designed with certain sized rotors in mind. Is the rotor too large? Maybe you have a 160 or 180 and it’s designed for a 140 or some such. Link to comment Share on other sites More sharing options...
maddmaxx ★ Posted May 21, 2019 Share #9 Posted May 21, 2019 Upon further review I think that there are several different 29er hub widths and frame widths. The terms "boost" and "super boost" come up in discussions. Given that your problem would be solved if the frame width allowed for an axle spacer on the rotor side of the axle of about 6mm you may have a wheel/frame mismatch. If the spacer works and if the tire centers up in the frame the wheel will work. You would see this if the dropouts had to be squeezed inward to tighten the wheel. If the dropouts had to be pushed out to mount the wheel you probably can't use this wheel. Hopefully you can take the wheel off and still measure the width inside the dropouts. Compare that to the width of the wheel hub over the locknuts. If for some strange reason they are the same measurement then I'm out of ideas. If the wheel is wider than the frame I don't know if it can be fixed. If the wheel is narrower than the frame, a spacer will make it fit but the wheel may have to be redished to center the rim. This is all a SWAG and I did not stay at a Holiday Inn Express last night. 1 Link to comment Share on other sites More sharing options...
dinneR ★ Posted May 21, 2019 Share #10 Posted May 21, 2019 Seems confusing if it fit in the dropouts. Hub spacing would be my first guess. And definitely check the rotor size. It probably has a 160 mm max. Nice video just for kicks. Link to comment Share on other sites More sharing options...

Does it look like there is extra axle on the non drive side? 142 is the thru axle equivalent for 135mm quick release for frames with 3.5mm locating slots. There were some early thru axle frames that did not have the slots and were 135 OLD. Not a factor here though as the photo clearly shows a quick release lever. As far as why the rotor is rubbing the mount, I got nuthin. 1 Link to comment Share on other sites More sharing options...

maddmaxx ★ Posted May 22, 2019 Share #26 Posted May 22, 2019 I believe the Nashbar 29er frame is a 135mm spacing for the rear dropouts. I haven't sussed it out yet but Mavic makes a series of adapters that insert into the ends of the hubs to adapt them to different axle styles (thru vs QR) and spacings. It might be that this wheel can be fit with an optional set of spacers???? Link to comment Share on other sites More sharing options...
maddmaxx ★ Posted May 22, 2019 Share #27 Posted May 22, 2019 The above is a very interesting 22 min on hubs. Unfortunately it doesn't mention adapters. Link to comment Share on other sites More sharing options...
donkpow Posted May 22, 2019 Share #28 Posted May 22, 2019 I have no idea what the problem is but here is how I would go about it. -Measure the bike dropout spacing. -Measure the distance from the dropout face to the caliper slot center (determining rotor position relative to locknut face). Go from there to check out hubs and adapters. I think if you are going to want an answer for this kind of question, you are going to need to look really close at specifications and build specs of the original bike. That should give you a hint.

I also though it strange that no one else was mentioning them. I didn't want to be the first so I pretended like they weren't even there. I suppose both Parr8 and the Facebook guy could just cut them off. Link to comment Share on other sites More sharing options...
