Oops posted now. 29er. Thanks.

Stans MK3 are junk and Stan’s know it so they changed the design. The MK4 is very good. I prefer the Spank Vibracore rims though. The Vibracore really works to mute vibrations. I’m not mountain biking nowadays and have a Spank Vibracore Boost wheelset for sale in the classifieds.

Yeah internal width makes a huge difference. I have some 42mm tyres that measure 48mm on a 28mm internal rim.

There don’t seem to be a lot of rim brake frames that can fit wider than 28mm. Are you riding a rim brake bike with 32mm or wider tyres? If so what frame and brake calipers are you using.

Droo what’s the advantage of going to Microspline over HG if you already have a HG driver? Better cassettes options, better shifting?

Were you on an MTB race committee? There were a few MTB events that had big title sponsors that could pocket entry fees but not many. Is there a single gravel event that has a major title sponsor that covers all costs? Doubt it. It’s not the glory days of MTB stage racing.

FYI - They are designed for bikes with clearance up to about 45 and tires from 35 to 42 while maintaining the air flow design of a semi deep rim.

Have you built up any of the Nextie 45’s with the ultra wide internal? I think it’s something like 29.

Let’s not get carried away. There have been a couple of incidents on that section. Regular makes it sound like it happens weekly which is just not the case. Same for Redhill. It’s happened before but it’s not a regular thing and I’d be perfectly happy riding there alone. Avoid the Hout Bay township area for sure because there are much better ways to ride up to or down from Constantia Nel

The Mungas been done on a ridged single speed but a bmx would be next level.

They cost $45 so R950 is in line with exchange and vat. If you want extra tall ones DM Jack Black on this forum.

I wrote that drafting does not help much for this specific event because of slow speeds, corrugated roads, extreme fatigue etc. Drafting has multiple variables. Aerobars don't and provide a small but constant benefit, even at slow speeds, for the duration of the event provided the rider uses them. The drag reduction on very high stack aerobars is marginal but the saddle pressure reduction and comfort resting position is substantial.

For sure. More relevant is being a USA cycling certified coach and having used power metes for field tests for over 20 years. Chung type testing road / TT bike position, clothing, wheel sets etc for a couple decades is a good start. Munga experience is an added but important reference point as specificity is a thing.

Me? Yip. 75hrs something. I mention that because if my slow ass avg moving speed was good enough to be faster than 86% of the field I know what the real moving averages are for each sector. That’s the reason for my view on drafting in this race.

However, in a 1998 paper entitled “Cycling Uphill and Downhill” David P. Swain wrote: “At very slow speeds (on the order of 16 km/h or less) air resistance is negligible, and drafting becomes nearly meaningless.” >>> Plus holding the line on corrugated rough roads is more effort than it’s worth. if you disagree what year did you do the Munga and what was your moving time?
