Description:Mach 4 (XTR Group)
The Pivot Mach 4 is the first choice for obsessive perfectionists seeking the ultimate cross-country mountain bike. With an unmatched pedigree, it's the most technologically advanced suspension bike made. The DW-Link suspension is active when hitting bumps and under braking, but resists squatting when pedaling.

The Mach 4's alloy frame and advanced linkage design make for a bike that is ultra-light but maintains excellent stiffness. Optimized for racing and aggressive cross-country riding, the Mach 4 is lightweight, agile and efficient. It is Cross Country, Redefined.

Strengths:My Blur XC was a few years old and I wanted to try something different; the Pivot Mach 4 seemed to fit the bill. So far the bike performs as advertised and is similar to the Blur in that it’s an awesome XC ride with an efficient pedaling platform. In the few weeks that I’ve had the Pivot, I’ve noticed a few things that it seems to do better than the Blur – the Pivot suspension seems smoother when pedaling over rocks/roots and it seems to better balanced with an upright pedaling position while climbing. I’m still experimenting with the suspension but it seems that there might be more options/distinctions with the Pivot design. As a standard suspension setup, Pivot recommends turning off the pro-pedal feature of the Fox RP23 (interesting). Of course you can do this with the Blur as well, but it feels like the Pivot has more pedal platform than the Blur in this configuration. Also, there’s a nice distinction when you switch on the pro-pedal set to its lightest setting (another Pivot recommendation). I love the feel of the front derailleur as it is bolted to the frame, and I departed from the recommended XTR spec and went with SRAM XO which I love as well. The Mach 4 frame is touted as being very stiff and not allowing much flex and I can attest to this. If you lock out the front fork and really stand on the pedals, it feels like a hardtail; definitely less flex than the Blur but in fairness my Blur needs a full suspension bearing job.
Weaknesses:The frame is not the lightest in the world, but if you have the coin to configure it properly you can spec out a nice light ride. Mine is 24.6 lbs with pedals and dried mud. I’ll have to provide another review later on its service requirements once I take it through a midwest winter. The Blur’s pivot points required frequent servicing and we’ll see what the Pivot requires after I give it the same treatment (beating the hell out of it).

Bike Setup:Fox 32 F100 RLC fork, a Ritchey Zero WCS Carbon Zero Stack headset, Thomson X4 stem, RaceFace Next SL Carbon Riser bar, SRAM X.0 shifters and rear derailleur, Shimano XTR M970 bolt-on front derailleur, Avid Juicy Ultimates, Thomson Masterpiece seatpost, WTB Rocket V SLT saddle, Shimano XTR crank, Crank Brothers Eggbeater SL pedals, DT Swiss Champion XR1450 wheelset, and Kenda Tomac Small Block 8 tires.
Bottom Line:Bottom line, the Pivot Mach 4 is a smoking fast super efficient XC machine and I couldn’t be happier. Its look and design is unique and definitely turns heads on the trail. Check it out - http://www.speedgoat.com/galleryB.asp?p=1243

Duration Product Used:3 months
Purchased At:Big Ring Cyclery (La
Strengths:Absolutely no frame flex and no noticeable loss climbing. Great customer service from Big Ring and Pivot. I had a couple of questions about the bike since there wasn't an XL for me to test ride in the area. The shop answered what they could and put me in touch with Rob at Pivot for the rest.
Weaknesses:I would have liked it to be a little lighter, but when you are 6'5" you can't have too light a bike.
Similar Products Used:Titus Racer X, Litespeed Tansi, GT Zaskar
Bike Setup:XTR, Manitou Minute MRD
Bottom Line:You are going to want more hours in the day to be able to ride this. Truly fun to ride.

Favoriate Trail:Gap Creek
Duration Product Used:3 months
Price Paid: $2000.00
Purchased At:Speedgoat
Strengths:This bike is awesome. Its light, fast and all but locks out the pedal bob. Climbs like a scared monkey and desceneds beautifully. Perfect geometry, Comfy to race over long periods with 4 inches in the rear but it still has a nice aggressive head angle.
Weaknesses:Absolutely none. If there is anything it would be the build not the frame. They only come in a few models so if your not happy with the XTR build or X9 build, go custom.
Similar Products Used:Mongoose canaan, TREK Liquid, GT Zascar
Bike Setup:SRAM XO rear, XTR front, Fox F100X, Juicy carbons, easton carbon cockpit, FSA carbon seatpost and cranks, Stans ZTR Olympic wheelset.
Bottom Line:This is the best frame on the market. The geometry, pivot link and rear wheel path make it a pleasure to ride. Technically it can not be faulted. And from a comfort perspective. AWESOME!

Strengths:Impressive craftsmanship with thoughtful attention to detail in the design and construction. You have to see the frame to truly appreciate it! Fast rolling, great handeling bike!
Weaknesses:none
Similar Products Used:Trek Fuel 9.9, Fisher hard tail
Bike Setup:pretty much stock
Bottom Line:Fantastic bike! I'm a female rider riding varied terrains and was looking for a no nonsense bike that I could ride/race short distances (30 mi) as well as longer distances (100 mi +) So far I have about 300+ miles on it and have found that it accelerates fast and is great on descents. My favorite feature is that it is an incredibly stable bike. No flex and great in the corners. I can't say enough great things about this bike! And...The customer service is outstanding..thank you Rob!

Favoriate Trail:Overmountain Victory Trail
Duration Product Used:Less than 1 month
Purchased At:Cycle Therapy
Strengths:Quality construction fit and finish. Great efficiency, super plush, respectably light (6lbs including frame, shock, BB and front der and headset) great handling and very stiff. ZERO frame flex. Integrated BB is easy to set up and with XTR, quality is assured. (3 year warranty on the BB) Intergrated front der required only trim to be dialed in. Set the first gear, set the out-board stop and done. Nice.
Weaknesses:I dont think the integrated headset brings that much to the table. I would prefer a King. Specific BB and front derailleur required. No flexibility there. Gotta run what they give you. Not that the parts are cheezy, its just some folks are picky like that. You decide.
Similar Products Used:SC Blur XC, Blur LT, Rush,
Bike Setup:Stans ZTR 355 and Hope Pro II wheels, Raceface Deus crank (2X9), 08 XT shifters, Shadow rear der, Front Der and cassette and 08 XT brakes, Thomson post and stem, 09 F100 RLC fork, RP23 shock, Avid Flak Jacket cables, Kenda Small Blk 8 2.35 tires w/Stans, ODI rouge grips, Monkey Lite XC high rise bar, Rocket V saddle, Salsa Flip offs, Salsa liplock.
Bottom Line:The bottom line is this bike has really impressed me with its paradoxical ability to remain super plush and ultra efficient at the same time all the while void of ANY pedal feedback. This bike moves forward with every pedal stroke and makes you feel faster and stronger. Like most XC race bikes it could get tiresome on long epic rides but that is not what this bike is for. For racing and blasting singletrack this is a hot ticket and it will keep the leg shavers happy. If you want more rough and tumble go Mach 5. Chris and Dave have got winners here.

Purchased At:Roaring Mouse Cycles
Strengths:Anti sag DW Link suspension design. Incredibly stiff and efficient climber (forget lockout). Compilient on small stuff. Fantastic out of corner handling.
Weaknesses:None so far.
Similar Products Used:Titus Racer X, Titus Switchblade, Ibis Mojo, Yeti 575.
Bike Setup:Mix of XT, XO and plenty of carbon goodies.
Bottom Line:Solid, fantastic new ride. You really have to see the frames in person to appreciate how radical the design is. No buyers remorse. Pivot's version of the DW Link design has a tighter, more cross country feel than the Mojo, which suits my riding style. To be fair, the Pivot Mach 5 would be a better comparison to the Mojo (also, a great ride). If you live in the San Francisco Bay Area (or not) contact Chris @ Roaring Mouse Cycles. Fantastic service, follow up, and up to date information. Zero attitude, and did not flinch at a million questions and requests Thanks Chris!
