Just got a used XTR M985 38/26 crankset. It only weighs 660 grams!!!
So, you upgraded your entire bike to a new bike? I like that!

1. I swapped my Reverb with a KS Lev (this week). The Reverb was fine, but I was tired of the cable scrub. My wife got the Reverb, so everyone is happy.
2. I got a custom shock tune from PUSH. The bike rides MUCH better now, especially with medium bump compliance.
3. I swapped out my Talas 32mm 150 with a Talas 34 mm 160. So, I road the crap out of the new fork in October and found it was fantastic when bombing crazy fast/tech/rocky/rooty down hill single track with flowing turns and berms. HOWEVER, it did not do as well on tight DH switchbacks or hairpin berms (compared to the Talas 32 150 mm). Climbs weren't an issue because I could always drop it to 120 mm. I knew this could be an issue before I bought the fork but I wanted to confirm/experiment on my own vs. just taking our great friends at Pivot's word on the 34 mm forks. I also had a back-up plan if the 160 mm geo didn't work out.
See, Pivot's perfectly reasonable recommendation is to go with the Float 34 mm 160 and drop it to 150. But I wanted a Talas. I noticed that the Specialized Stumpy Evo Carbon comes with a Talas 34 mm 150 and I asked my LBS if I could buy that fork. Answer is no. HOWEVER, Fox told them that you can easily convert your 34 mm 160 to a 150 by simply swapping out the Talas Lower Assembly Cartridge from the 160 mm/120 mm to the 150 mm/120 mm (Fox part number 820-02-154-Kit at $75 US). Needless to say, I went that route and made the change this week. For the Geo geeks:
Talas 32 mm 150 ATC = 520.9 mm
Talas 34 mm 150 ATC = 527.9 mm
Talas 34 mm 160 ATC = 537.9 mm
BB height rose around .25 inches, which is far better than the ~.5 inch rise at 160 mm
For the folks out there who want a 34 mm Talas 150, there is an option for you. It will require an extra $75 US, so it's up to you whether it's worth it our not. It was worth it to me, plus I have both cartridges and can switch back to 160 mm for any future needs.
Dan and Ken, maybe talk to Chris about the Talas 34 mm 150/120 as a third option for the 5.7c? The bike is an awesome Enduro/Super D rig that performs MUCH better with the 34 mm fork. Floats are great, but being able to drop to 120 mm in races and rec rides is a huge difference maker on steep climbs. Just saying.
... my humblest apologies to kenbentit, but i added a DOSS to my M4X...
on the other hand, i don't have any street cred to protect anyway
i like it because this way i only need one post for all situations
i need to develop my crashing skills...
My "upgraded 429"...
Previous: 429 alum, XX 2x10, Speci Roval EL alloy wheels. Migrated Blacklite, shifters, The One brakes, bar, stem, grips, pedals, tires; all else is new.
Got a familiar trail in with perfect dirt. Something would have been very wrong if I hadn't been blown away by the ride. I kept trying to find similarities between my old build and this one. All I could come up with is that they both feel stiff and fast. Aside from that, it's an absolutely different tool. I'm convinced the hoops have as much to do with the ride feel as the frame. Probably more.
Climbing: Overall greater stability. Decreased head angle didn't affect stability by any measure. Feels slightly more maneuverable than the alum build, thanks to instant acceleration of the hoops and lower BB.
Descending: Stunning performance. My alum bike would hit a ceiling in the rough, where control started to feel marginal. Wheels kicking left and right, just feeling a tad out of its element. This bike is absolutely smooth, unbelievable feedback dampening. Still feels aggressively stiff and fast. Its ability to provide control in rough spots reminds me of my long-travel bike with Flow rims. Which is a pretty shocking revelation for an upgraded XC bike.
It weighed in at just under 27.5 lbs. I'm pretty sure my alum bike weighed slightly more, if any. I'll take the increased stiffness and dampening and forget the weight. This bike is surely going to horn in on the other half of my quiver, and it'll be a bikepacking animal when that time comes.
Kudos to Pivot for designing great bikes. (And thanks for getting me on the trail with the loaner shock.)
A couple of changes...
KS Lev post - 100mm
ODI Ruffian grips
Swapped out the front rotor for a 180
Now if the trials would just dry up
Being 36, the young fella's half my age where giving me an earful about being more careful in my old age.
This bike constantly amazes me with it's ride quality and handling. Still waiting for the day I feel it bottom out.
changed the ff on my M5:
1. Hope Stem 90mm (from a 70mm)
2. WTB Rocket V Saddle
3. Yumeya 11T Tension & Pulley wheel
4. Mavic SLR Wheelset
5. Continental X-King on my rear
6. KMC chain
7. XTR Pedals & Drtivetrain
8. Red Brake Levers on my Hope X2
padyakol = padyak all the way
Wow! I'd imagine your bike went had some good weight loss after these upgrades?

Hey Swinkey, great looking build!! Don't forget a seat dropper. It's a game-changer!
My 429 got new pads and rotors today.
I put a small scratch to the top tube in crash mid-October. The bike did me this:
I could start riding any day now....
I mounted the XTR M980 2 ring cranks and a new M985E2 FD yesterday.
Put a new spring, heaviest one fox sells( yellow) , on my vanilla fork. Hope this one doesn't bottom out too easily like the green.
Going to be a long winter ....
Decided against getting an older DH bike to much around with on park or big shuttle days. Instead I beefed/quieted the Firebird down a bit.
- picked up an aluminum rocker for DH days to go with ....
- a 2012 DHX RC4 shock w/350# spring (testing phase)
- a replacement set of needle bearings for my DHX Air for XC riding
- an XO med cage Type2 derailleur (using the original '09 XO 9sp shifter)
- new chain (SRAM 991)
- new chain rings, a gold 24t Blackspire and a 36t SLX
- new cables/housing on shifters
- new cable/housing on KS Supernatural
- new 2.35 Nevegal for the back (or a 2.35 Prowler XT)
- new 2.5 Minion DHF XC for the front
- fresh pads on the Saints
- fresh oil in the Totem
- new WTB Silverado SLT Saddle (hasn't arrived yet)
- replacement seatpost QR lever
Its going to be a great year!

So, over the last 6 weeks or so, I've done the following:
- Replaced the tyres after destroying the rear Larsen.
- Changed to NN front and RR rear.
- Replaced rear linkage setup due to original double row bearings dying.
- Entered the first race of the NSW State AM Series.
- Said race was pretty wet still, so bike got VERY Dirty Like, dirt in places it didn't know it had!
- Gave bike complete overhaul (was time anyway after 10 months), with a full strip down, clean and rebuild.
Now it's running super smooth, and somewhere in there the bike has dropped 200g, and is now at 11.40kg (25.13lbs). I'm guessing the tyres are the cause of this
Looking forward to the weekend to ride my baby again!
Got new rotors. Magura Ventidiscs 180mm and flat sweep back bar
- Changed the rear tire from Slant Six to Navegal 2.35 DTC.
- Changed to a 36T star rachet on my DT350 rear hub.
- Just ordered a Gravity Dropper. Hope it get's here soon. Multiposition 1in and 4in.
Replaced the stock bars on my FB with some deity cz38's. 760mm. Way more comfortable. Very noticeable difference
What have you done to your Pivot Cycle lately?
I did a tubeless conversion on my 2013 Firebird. I used American Classic tape, Stan's rim strips, Stan's sealant, and Schwalbe Hans Dampfs on the DT 530 rims. The setup was painless and has been solid so far with no burping after 2 rides at 30 psi.
Diamondback Mission 4
Cannondale: Perp, SuperSix
Tomac Buckshot SS
Pivot Mach 5.7 AL.
Added a 0.93^3 in volume spacer to the Fox CTD shock. It is the largest spacer for that shock. I don't bottom out anymore but still use all the travel often, which is a good thing. I've only dropped the sag ring off the shock once on a big hit (3-4ft) that I didn't land correctly.
Also added more fox fluid on the Fox Float 34 CTD @ 150mm. I have added a total of 20cc. I think it was just the right amount for me, not bottoming out anymore but still using all the travel.
Both changes will need a rebound adjustment as I felt with the same setting it is now faster than I would like.
I weigh 195lbs with gear and my pressures are 170psi and 70psi.
