For a 22mm to 42mm tire range, I wouldn't hesitate to select rims that are 20mm wide internally and 24mm wide externally. - They are lighter, so since neither rim gives aero gains, you may as well higlve lighter wheels. - They are plenty wide to easily and competently handle your tire width range. - They are offset and allow for a better build. For years I used H+Son Hydra rims on my gravel bike- it's 20mm internal and 25mm external, and 23mm deep. So pretty similar measurements as the RR421. I used 42mm WTB tires and 43mm Panaracer tires and never thought twice about tire width compared to rim width when I was actually riding. |

I can't say that it looks (or feels) particularly bulby to me, to have 38s on 18mm internal width.

Thanks everyone for your inputs and experiences - I've decided to go with the RR421.
A question on spokes choice. Since the RR421 rim is lighter and has a smaller profile than the RR481 (and therefore likely less stiff) should I be choosing aero comp spokes all around? I had considered going with aero comp / aero lite combo if I'd chosen the RR481, but with the asymmetrical RR421 rim I'm guessing that's not really going to help much other than a miniscule amount of weight savings which is of no interest to me. I'm choosing the bladed spokes not for "AeroGainz", but to help me with the build to avoid wind up. This will be the first set I build. I'll be using DT's squorx brass nipples. Sorry OldPotatoe, if I lived in the US I'd for sure be employing your services, alas I do not. Much as I'd love to. |

I think worrying about windup is overrated. If it were me, I'd be using good old double butted spokes. Bladed spokes are a pain to work with.

Get the Park Tool spoke clamp and the DT Swiss T-handle squorx wrench. That combination + working very slowly should make for an enjoyable build.

“Da Interwebs” is full of fearful stuff saying DB round spokes will wind up and bladed spokes are easier to observe. I’d be thrilled if that could be debunked - bladed are quite pricey. |

Great shout! Will pick up the Park Tool - the DT T handle tool is already in the mail to me

If you aren't interested in the 'aero-ness' of oval spokes, nor the 'weight savings, I'd just use DT Comp spokes(and the brass nipps)...

BUT, these oval are thin spokes..'windup' happens more easily. AND the resulting wheel, when compared to a wheel made with round, double butted spokes, performs just the same...Lots of marketing going on. Proper choice of appropriate rim, spoke count, way more important...along with a good build.

Thanks OldPotatoe , I think you've got me onto the round spokes train for this.
Question, with the asymmetric rim would you just go with Comps (2,1.8,2) all around or would you consider Revolutions (2,1.5,2) for the rear NDS and front DS? Interwebs says using heavier spokes on rear DS and front NDS (on disc builds) will even up spoke tension and improve reliability but I wonder if the gains in doing this are negated by the asymmetric rim anyways and may even result in a weaker wheel considering it's a light/shallow rim. |
