@isleofmant- see the question/answer above yours. On Roval and DT hubs it is not possible to convert 360 into 350 or vice versa.

Regarding individual hubs- Roval wheels are engineered and tested as a system, so we do not sell individual components. It would effect your warranty, but if you wanted the 29mm alloy rims with a 350 based hub, grabbing an off the shelf 350 DT hub would be your best bet.

I had misunderstood @spmls's question as - regarding freehub body only (Shimano 9-10spd), I guess we were both asking the same question i.e. about swapping the complete internals of the hub.

About using an off the shelf DT 350 hub with the Roval alloy rims (on a 2015 Enduro frame), will this not be an issue because a regular 142 mm hub, will be lacking the 2 mm offset which the 142+ hubs have on the drive side flange, and hence the cassette will sit 2 mm closer to the center of the hub. This would cause chainline issues - riding on the largest cogs of the cassette will cause more cross-chaining than with a 142+ hub. Also, my understanding is that the brake-rotor should be unaffected in this scenario.

@isleofmant- to be clear I'm not endorsing the use of a DT 350 hub with our rims. But if you did, your rotor would be in the same place as on your 142+ hub and with a standard 142 drive side endcap you would have to do a bit of rr derr adjustment, but nothing too involved. Plenty of riders out there using standard 142 spacing hubs on SBC frames.

Thank you Joe, for the confirmation. I found a compatibility guide on SBC's website, which also confirms that the regular 142 mm hubs can be used on the 142+ frames: https://media.specialized.com/support/0000010510/0000010510.pdf

I am curious though, when switching from 142+ to 142 mm regular hub, apart from the rear deraileur adjustment, how does the chainline itself get affected?
Did SBC do something proprietary to the crankset spindle length on all 142+ frames, to keep chainline same as for a regular 142 mm? If not, it seems like all 142+ frames actually have the "abnormal" chainline compared to the regular 142 mm frames (in which case, for 142+, the cassette is 2 mm away from the center of the hub, and the non-modified chainline would be better for larger cogs, but smaller cogs would see worse cross-chaining). If this were true, going to 142 mm rear hub will restore the chainline seen with all regular 142 mm frames.

If SBC is calling these frames 142+, then what exactly is proprietary apart from the wheel? Is the deraileur hanger offset by 2 mm? The width between the two frame ends would be exactly same as a 142 mm frame (since the axles on the 142+ rear hub use a drive side axle cap that is 2 mm shorter, to make up for the +2 mm drive side flange offset), so I am failing to understand what makes the "frame" 142+.

Sorry for so many questions ... just laying out the thoughts.

Read some threads on this, and here are some of the suggestions other members had, on why SBC frames are 142+:

- The 2 mm outward offset of the cassette could cause some rubbing.
- They probably designed some extra clearance at the rear dropouts, for the chain when in the small cog.

That makes sense regarding why the frame is 142+. My questions above, about the chainline, still remain though.

Thanks for answering my earlier question, I've got one more: I'm planning on swapping in a Roval 135/142 hub from an alloy Traverse fattie to a Traverse fattie sl that has a 142+ hub on it currently. Are the spokes the same lengths so I can just remove the nipples on both wheels and swap the hubs without relacing the spokes?

So I recently purchased a set of roval traverse fattie alloy wheels. They have a 29mm internal width which I've found rounds the profile of my 27.5x3.0 tires too much. I think a wider rim would be a nice upgrade for these tires.

So my question is, is it possible to upgrade my rims to the new wider 38mm version?

A follow up to that, where can I get ERD measurements for my current rim?

To clarify, I have this wheelset

I want to do something possibly stupid. I'm looking for a set of carbon wheels for my do anything commuting/traveling/packing drop bar bike. I currently have an All-City Macho King but I may swap it out for the new Sequoia.

I really like the Traverse SL that I have for my mountain bike. What is the max pressure I can run on these? Can I use my DT swiss end caps to convert standards? My current bike is 15mm front and QR rear. The Sequoia is also weird 12x100 front and 12x142 rear.

Is there a Roval carbon wheel that is useable around 70-80 PSI with the Roubaix Pro 2Bliss tyres? I may jump into the new 2Bliss Sawtooth tyres. I've seen the Sequoia in person and it's pretty nice but stock weight was almost 27lbs on the green one.

@zuku- SBC PN - 30015-1051
@GTR-33- Traverse SL front hubs can't be converted to 12X100, but the Control SL 29 can. That'd be your best bet from the MTB line. I've got a message in to the road team to see if there is anything that would be more rad in their line.

Hi Joe, I'm looking to convert my Traverse Fattie SLs to boost spacing, but can't find the part numbers for the adapters. Care to hook me up with some digits? Do my wheels use the same parts as the Control SLs? Thanks!
