I built this over the summer. It's a Santa Cruz Classic Blur. I pretty much ran it up as a basket case job. It was a good education in how, and how not to do bike mechanics. Presently I am doing battle with brake squeal. I learned nothing though, as I am contemplating doing another one.

I'm looking to pick up an Ibis mojo hd3 in the spring. I'll demo it first but I gotta say I already dig DW and if I like the wheels then I'm in and will cost the same as my truck! I've never owned a car that costs more than my bike, so I'm staying consistent there! How do you like your mojo?

Willbeer is being funny and describing the riding experience on a singlespeed. Seated riding. Out of the seat riding when it gets steep. Walking when too steep.

Oh my^^^^^. I have a friend that builds MTB snow trails in Wyoming. She'd understand. I'd cry.

My last ride of the fall season in Moab a couple weeks ago.

Built my first wheel today

Well, finished it today.

BD has to cut corners somewhere to sell at the price point they do and it's the hubs. I've finally got into enough shape where spinning 85+ rpm is a possibility and I was starting to outspin my freewheel at about 90 rpm This is kinda hard to describe unless you have experienced it but it manifests itself as slack and clunking in the drive train, it was also noticeable on the transitions from standing to seated climbing and vice versa. On top of that the Vuelta wheel picked up some threads, probably from a tire bead and sucked them into the freewheel mechanism. I managed to fix it, but it took an ultrasonic cleaner, specially modified 12mm Allen wrench and much swearing. The Vuelta that BD was buying then is kind of a frankenstein between a freehub and a freewheel, difficult to get apart, not user friendly serviceable and not easy to find replacements. Lots of seal drag too and also no readily available replacement seals.

I've also got disc brakes and 130 OLD spacing so hub choices are limited.

I scored on a discounted White CX Ti hub and mated it with a fairly heavy 29er rim (Alex TD17) and a 36 spoke 3 cross build. Sapim double butted spokes and Al nipples. Total cost was $310.

I used the bike as a truing stand and invested in a $38 Harbor Freight dial indicator and snake head clamp that I need for work anyway. It ended up at 0.004 TIR laterally and 0.008 TIR Radially so it's true to about the thickness of the decals. the big disadvantage to doing it this way is guestimating the dish/centering with no flat surfaces to measure from I ended up being about 1mm off to the right. The machinist in my past came out and it's a bit like indicating in a 36 instead of a 4 jaw chuck. Not difficult, but does require some sense of what the metal is doing and patience. I also got really aggressive about the stress relieving process.
(put the axle on a block of wood, grab the rim and try to taco it working your way all the way around, flip over, repeat)

All of the NDS nipples got a dollop of green (penetrating grade) Locktite on completion


I was primarily interested in getting the hub situation rectified, but as a bonus it's about 200g lighter than the old wheel with a wider stronger rim to boot.

Took it out for a spin this afternoon and no alarming pings or noises so I must have done something right, The ride is noticeably more comfortable too. I'd attribute that to the fact that the OEM wheel has oversize blade forks that have about the same cross sectional area as a really thick round spoke. The double butted ones would be springier. How that will play out as far as the potential for future fatigue failure only time will tell.

One thing I will do different next time is to use grease rather than thin oil on the DS nipples. That would make bringing them up to tension much smoother with less slip/stick action. The NDS the torque is so low you could probably leave them dry.

New Santa Cruz 5010 carbon. It's awesome. Managed to squeak in a prework ride up Paseo Miramar to Parker Mesa Overlook. A tiring but good way to start the day.

Hey J

Check out the Light & Motion stuff. I use an 800 and a 550 lumen, one on the helmet and one on the bar. You'll spend around $250 for both and possibly be hella store.

Had a couple of Niteriders over the years, they are way overpriced now and they gouge you on spare parts. Great luck with Magicshine at 30-40% of the price. 2 on the bars for even coverage, one on helmet to look around corners, you can ride anything. Using just a helmet light sucks, the steep angle washes out any contrast, it's like skiing in a whiteout. I'm actually using a couple of Chinese rigs now, $30 on Amazon for the whole kit. The batteries didn't last but a good replacement from Magicshine is compatible. Yeah, we do a lot of night riding!

Tallboy LT, awesome machine!

For night m-biking I use a combination of a 700 lumen bar mount Nightrider and a 750 lumen Lupine dual beam helmet mounted unit. I love this combination for having different beam patterns, brightness options and bar/head tracking. Super fun!
