To the OP...
WhatsApp me the details and as many pics as possible and I can give you a sensible way forward.
I wouldn't recommend rebuilding the Mk3 wheels as they WILL crack at the spoke holes.
Most cost effective solution is riding the front wheel as-is if it's ok, and building a new rear wheel.
I have some budget-friendly options.
Get me on 0.8.3.4.5.2.8.7.1.6
My friends at Spank gave me a set of rims and hubs to build up, and this was the result:
Spank 359 Vibrocore rims on their Hex Drive hubs with double butted Pillar spokes and green anodised nipples.
There's no freehub installed because the buyer of these wheels will specify which type they need.
Let me know what you think!

Oh how the world change engineering has back fired
Yup. Prices and costs have escalated substantially, unfortunately.
Shipping a pair of rims from Nextie to me costs $140 via FedEX.
I can’t rely on the post office.

Those are great value for money.
For me to build something equivalent you’re looking at around R20k-ish.
Best is for me to send you a few options with itemized quotes so you can pick the best possible hub and rim combination for your money.

15 minutes ago, cadenceblur said:Are darkhorse a great option, I’m eyeing the 50mm’s front and back, just worried about stiffness. My current wheels are quite stiff and I tip the scales at 97kg.
At 97kg I would opt for a set with more than 20/24 spokes front and rear.
I would suggest 24/28 at least.
A custom-built set is easily available in that configuration.

Its for xc riding, I weigh 85kg.
I saw the Lyne pulse wheels that goes for 17k would love to know your thoughts on it ?
and then a question to everyone, for those who moved over to Carbon wheels from Alloy was it worth it ? Does it make a 17k difference 😂
Thank you
If I had to make a recommendation for R17k I would say use your existing hubs and get new carbon rims and light bladed spokes.
Add R5-8k for a good set of hubs.
The much lower weight of carbon rims makes a huge difference in ride feel.
I’ll comment on the Lyne set once I have seen the specs.
I'd love to sell someone a new 27'5" rear wheel, but if you're looking for more agility, install a dropper seatpost and use it often!

Very cool engineering in that design but... do current and traditional hub designs cause such a nightmare headache that we need to re-invent the wheel? Not for 99% of us.
And GBP825 / R17 000 for a set of hubs? That's in DT Swiss 180 territory. Or Chris King.
A niche product for a niche target customer.
Once you bring a proprietary design into the cycling industry you either need a bottomless bank account or a logo like SRAM to make it work in the long term.

The Sedgefield 500 ultra gravel bikepacking race across the Garden Route is an epic journey of endurance and discovery that will leave you inspired and in awe of the natural beauty of South Africa. 500kms with about 7000 meters of elevation. This incredible race takes you through some of the most breathtaking scenery on the planet, from lush forests to pristine beaches, and everything in between.

The rugged terrain, steep climbs, and challenging descents will push you to your limits, but with each pedal stroke, you will feel a sense of accomplishment and satisfaction that can only be gained through perseverance and determination.
Is there a route map available? The one on the website only shows 2 shorter segments.
Just finished up some disc-brake road wheels.
1375g set with 40mm deep rims.
Tubeless-ready.
Almost makes me want to buy a road bike!
12 hours ago, robbybzgo said:Not mentioned above but I purchased some Stan's Valors (carbon 29") about 4 years ago. They are superb and very lightweight, so am I (that makes a great combination).
Just purchased another set, second hand (no longer available new) in 27.5 size a few days ago (on BikeHub).
Can't wait to fit them and ride.
Yes it's a pity Stan's don't have any carbon rims at the moment.
That said, their alloy options in the Mk4 range are superb.
Their Crest Mk4 has a 25mm inner width and weighs only 399g per rim, placing them squarely in carbon territory, for far less money.
Pair the crests with a light set of straightpull hubs and bladed spokes and you have a 1450g XC wheelset for under R15k.
Reviving this thread a little, since there are plenty of options and many people may want some info.

Sounds like your rim has a flat spot, which is practically impossible to remedy.
Unfortunately the AMC rims of that era are very soft, and ding and dent very easily.
The long term solution is new rims.
Arch Mk4 rims are 28mm inner width and 491g per rim - a super combination of width, durability and light-enough weight.
For reference, the lightest 29er rims available now are Crest Mk4, which are 25mm inner and 399g per rim.

So awesome!
Looks to be twitchy AF with such a short stem though....
11 hours ago, Johan1983 said:What rims to buy?
It depends.
where will you ride most?
Whats the spoke count of your hubs?
Dlo you need rims only, or a new wheel set?
Carbon or alloy?
What’s your budget?
I have see that if there are too many BB spacers installed, the end cap doesn't thread in far enough, and the crank arm falls off within 20km.
Ask my riding partner on my first Sani2C - 15km into stage 1 and we had to go full McGyver-mode when his left crank arm came off and the end cap went missing.
Incidentally, a QR skewer works well holding things together. Better than cable ties.
On 11/28/2023 at 7:03 PM, RobertWhitehead said:I had an M8000 that did not have one of those and the non-drive side crank arm kept falling off. No matter how tight I made the bolts it kept sliding off.
I had the same issue on the trainer and what I found to work was taking a piece of wire around the outer bolt before dropping into the hole.
That little thing really boggles my mind. That little pin breaks off quite easily over time but if there's lots of gunk and crap the arm stays in place but the moment you clean the crank and spindle it continues to come loose.
The left arm will only fall off if part #5 (look at the diagram above) isn't snug.
Install the crank arm (without stupid stopper plate) in this order:
1. Slide crank arm onto spindle.
2. Snug down part #5 (I forget what it's called - I'll call it the spindle end cap, for lack of the correct name)
3. Tighten pinch bolts.
The pinch bolts squeeze the crank arm onto the spindle, preventing the spindle end cap from unscrewing. If that end cap stays put, so does your crank arm.

Nic, thank you, you really seem to know your stuff.. I’ll definitely give you a shout if I decide/have the funds to do a proper upgrade..
where do you operate from.?
I work from my garage...
I live in Wilderness, near George - been here for 3 years now, moved from JHB.
99% of the wheels I build go somewhere else by courier 😆

Such a cool bike!
Definitely more of an allroad bike than a gravel bike.
These would look HOT on that bike:

I only know of one Wheelbuilder, William’s Bike Shop in Somerset West.
If you don’t come right you can courier the stuff to me.
