A 29" Nobl tr37 rim is 450 grams for the front, 515g for the rear.
A 29" dt swiss ex511 rim is a good quality aluminum equivalent, and it weighs 570 grams.
So assuming identical hubs and spokes, you're saving about 175g of rotating weight. That's not nothing.
And if you're less smashy, there's even more weight to be saved (relative to their aluminum equivalents) on the more xc oriented carbon wheels.

Anyone have any experience with Zipp 3Zero Moto carbon rims? Seems like an interested concept but not aware of anyone using them (yet)?

I asked shop bro for his take on Carbon cuz he swapped the same set among a few enduro bikes I think it was that brand out of Kamloops, he said they probably weighed about the same as aluminium but they never went out of true/ the spokes never got loose so the big thing for him was NO maintenance

I experienced another side of that benefit last weekend when I flung a big cobble into my spokes. I had a moment of panic when I heard the noise, thought my entire wheel and drivetrain had exploded but no, just 2 spokes on the drive side cleanly broken. I twisted the stubs around the neighboring spokes to get them out of the way, spun the wheel which was still perfectly true, and went on to merrily smash my way down the trail. I replaced the 2 spokes that night, re-tensioned everything, wheel is back to looking like new.
Before flying to France last month I ditched my worn out summer rubber (2.4/2.5 Maxxis) and mounted some fresh 2.3 Specialized tires. My usual pressures felt off when squeezing the tires so I went with what felt right given the conditions (loamy with a chance of wet as shit roots). That turned out to be significantly too low on the 1st ride. The rear took a number of massive hits which would have dinged the shit of my alu DT rims but, other than loudly complaining and occasionally burping a drop of sealant, handled it like a champ.
I kinda miss the buttery feeling or alu in the rear but given my propensity to damage things I think carbon is the way to go for me."Your wife being mad is temporary, but pow turns do not get unmade" - mallwalker the wise

This was my 1st experience with carbon wheels - was on a fairly big-ish backcountry ride and broke a couple spokes on a rowdy descent. Did the same as you... continued on my way. Wheel never went out of true and I finished the ride with little drama.
I *did* have the wheel rebuilt with standard DT Swiss DB spokes instead of the weird "aero" spokes I had the wheel built with. Still not sure about those spokes...

I hit a downed tree at speed a few years ago with a set of enve carbon rims. It ruined the tire (big wobble afterwards) and went terribly out of true. I figured I ruined the rim. Took it to a shop where they looked it over, trued it up, might have replaced a few spokrs, but ultimately sent me on my way. They ran great for years afterwards.
My body was not as resilient as those rims and I'm certain that would have tacoed an aluminum rim.

Yeah, it really depends on the spoke. I've had some generic aero spokes from some random asian company - those things all started breaking after ~1000 miles. But I've only managed to break one Sapim CX-Ray ever, and that was when I smashed a large rock into it. But those things are fucking expensive, so they'd better hold up really well.

CX-Ray are pretty phenomenal but pricey, have run them on a few race wheels over the years, actually make truing them a bit easier as you immediately know if they're twisting. I've broken a few, but all(?) of them from sucking a big stick.
Have had a CX ray spoke pull through the rim of a carbon reynolds black label a few years back. Immediately warrantied, but does speak to the spoke strength I think. I was hauling down a descent and hit a square edge waterbar/rock hard.
Have also broken a few spokes on a Roval carbon wheelset and rim stays really true, but did lead me to putting in an insert to dampen the impacts a bit. Ride alloy rims on other bikes and think the weight/ride difference is a bit overblown in most cases.

I've recently gone carbon for reasons out of my control.wush I'd have gone carbon donkeys ago. They feel more spritely and faster folks say they feel more harsh but I've not felt that

So far yes, but hasn't been too many rides to say for sure, also bumped my travel up to 160/140 from 130/120 which probably smooths things out. I broke probably 3-4 last season over about 1500 miles and this season broke 1-2 but that was from a really dumb line through some rocks and roots.

I’ve ridden them extensively, and liked them a lot. They’re heavy for carbon hoops but the ride quality is excellent, and I never once pinched riding them.
Speaking of which, I have a set laced to XD Original Onyx hubs I’d be willing to part with now that my bike quiver is fully switched over to Shimano.

How hard is it to swap Magura brake lever blades? Or do I need to swap the entire brake lever assembly?
I've got a set of MT7s and MT5s, and I may want to switch them at some point this winter.

Probably easier than not stripping the bleed port screw out. I believe I did swap to the single finger levers when I had some MT brakes, but it was ~4 bikes ago. I do remember not having to swap the entire assembly out.

Easy. You just peel back the sticker plate, then gently tap out the pivot pin with a punch. I recall there being a video from Magura with some tips on it.

OK, how do I make a Kinetic trainer though axle adapter work with the hanger on a Salsa Warbird? The hanger is held in place by an axle stud cap nut, but the adapter won't fit through the 8mm hex opening on the nut -
I could drill out the nut enough for the adapter to pass through, but then tightening / removing the nut becomes an issue. Seem like a collar that protrudes past the frame and fits both over the axle stud and inside the frame hole would allow the nut on the adapter to hold the hanger in place? Shirley this has been solved somewhere?
