Well except for the Masterpiece seatpost that my pusher forgot to give to me when I was there today.
I will put her through her paces properly tomorrow night at a local Dusk to Dawn race so should have some good feedback on the Jet after that.
Updates since my preliminary build are:
  • Stans Arches laced to gold Hope hubs via DT Competition spokes (handbuilt by me)
  • XTR M970 crankset
  • White Jagwire housing and inner

Full build (minus the Masterpiece)

  • Frame - Jet9 (L)
  • Crankset - XTR M970 inc BB cups
  • Rotors - Alligator windcutter inc bolts
  • Brake - front Formula Puro (ti bolts and a2z guide
  • Brake - rear Formula Puro (ti bolts and adaptor)
  • Cables and Housing Jagwire Ripcord
  • Cassette XT
  • Chain KMC X10SL
  • Front derailleur Shimano M771 with ti kit
  • Rear derailleur SRAM X9 with ti kit
  • Fork 2009 Reba with Push-loc
  • Grips Ritchey foam + plugs
  • Handlebar KCNC Bare Bones
  • Headset Token TK116TBT
  • Top cap and bolt Fast Freddy + ti bolt
  • Headset spacers Carbon
  • Pedals Eggbeater SL
  • Skewers KCNC ti
  • Rim tape Stans
  • Saddle Selle Italia - SLR
  • Seatpost collar Token ti
  • Shifters X9 with Matchmaker and ti bolts
  • Stem Ritchey 4-Axis with ti bolt bolts
  • Wheels Hope Pro2 hubs laced to Stans Arch rims via DT Competition spokes
  • Seatpost Thomson Masterpiece with ti bolt kit
  • Tyres Maxxxis Crossmark rear and Ignitor front
  • Current weight 26.6lb.

I am a little disappointed with the weight but know that the Ignitors and Crossmarks are not the lightest options out there.

Unfortunately I dont have the photography skills of others but I am sure you can get the idea:

Shazam! Very nice build.:thumbsup:

If you haven't run the Windcutters before, it takes about 6 hard stops to bed those suckers in with the pads until they really start to shine and perform well. I trust you are using sintered pads and not ogranics...

Have fun in your marathon race aboard the white steed.

Nice build.

Tires may not be the lightest, but they're not the heaviest out there and they work well with the tubeless setup (from my experience with them).

Agree GLG.
The Ignitors have always been a favourite of mine and the Crossmarks also seem to work well in the conditions over here.
The track on the weekend is pretty sandy in places so I think I will be glad of the Ignitor up front.
Will also be taking a wheelset with a Rampage on the front which I may break out when the track gets chopped up late in the piece.

I like the Maxxis. I will say though, if you're going to take the weight penalty, go for the Ardent. It rolls faster than the Ignitor and will negate you having to switch up to a Rampage for the chopped up terrain (in my experience anyway).

That is really...

nice! Is your fork at 80mm (appears to be in the photos)? I'm interested in your ride report. Good luck in your race. Thanks.

Yep. Set at 80mm at the moment.
Will see how it goes at that but may swap it to 100mm if I am not happy.
So far so good on trail rides although I have hit my chainrings on logs a few times.

You could save weight w/ other tires yes but.... Would you still have a bike that was fun to ride?

I've just started re-thinking some of my weight saving parts starting w/ tires. What good is a feather weight bike if you still have to ginger foot it down the hill? Esp w/ that rear travel. My Maxxis/Kenda combos have had more than their share of pinch flats. (Please refrain from the tubless pitches. I'm not a fan of dinged rims either.)

After reading this

I'm rethinking thin tires. Ask me again in the fall, perhaps I'll be back to lighter, pinchier tires.

By the way, that is a gorgeous bike. Have you had much experience w/ those rip cords? Long lasting?
Why Ti bolts on an X9. Still ligher than X0 w/ Ti?

Sweet build

I know your going to be loving that beast. Nice build. Kept your eye on the weight I see.

I noticed you used a lot of TI hardware. For the entire build how much weight does the TI hardware save?

Thanks and enjoy!

Ti bolts bring the X9 down to a similar weight to the X0 for about half the cost.
Of course X0 with ti bolts would be lighter again but then you would be up for a substantially greater cost.

wow! that is beautiful!

not sure what the complaint with the weight is...you have arches and not 355s....you dont have a stoopid expensive XTR cassette...etc, that is a GREAT weight for a 29er FS that can actually be ridden. is it setup tubeless?

Yep, tubeless.
Quick report from the Dusk to Dawn event I just completed overnight.
I could just leave it at WOW!!!!!!!! But I will try to convey some proper thoughts.
The Jet climbed effortlessly over what was a fairly hill course. Much of my overtaking happened in these climbing sections. No bob anywhere, ever.
Obviously if there is climbing there is also downhill. Stand slightly, weight back and go. A slight weight shift was all that is needed to guide the Jet through the trees.
The course had plenty of rocky sections and even with only a 80mm travel Reba I was able to ride over and through sections that I would have been finessing on my previous hardtails.
IF there was one "negative", it would be the usual of slow handling through tight switchbacks. There was several of these on the course and I struggled with them at the beginning. It took a few laps before I was able to honestly say that I was in control of them. However, on the positive side, the Jet has the stability to get away with the slow speed manouvers that were necessary to negotiate these bends.

After this event, I can see no real reason why I would want to change my fork travel out to 100mm and will be staying at 80mm as recommended by Niner.
