Why We Like The Mach 4 SL Carbon Pro X01 Eagle Mountain Bike

Pivot's engineers designed the Mach 4 SL Carbon Pro X01 Eagle Mountain Bike for those of us who are of the pedal-your-own-way persuasion, with a featherweight construction that's stature is anything but, offering stiff control and power that scales in at a whopping 300-grams below the previous Mach 429 SL. The new Mach 4 SL takes queues from the venerated Mach 4 and 429 SL, bringing the 4's lightweight and nimble attitude to the trail. Plus, the SL's progressive cross-country tuned setup is made for soaring to the front of the pack, gliding over slick root gardens, and charging forward to earn your spot as the KOM.

*Due to unprecedented demand in the global supply chain and the bike industry over the last 18 months, material weight and exact components are subject to change. We are working diligently to keep tech specs updated, and any adjustments will be minor. If you have any questions, reach out to a Gearhead by chatting online or calling 1-888-276-7130.

  • Soar to the front of the pack with Pivot's new XC rocket ship
  • Steep seat tube angle keeps you perched for the attack
  • Take on chunky terrain, and power to the top with a moderate head tube
  • Vertical shock layout improves stand-over height and cage clearance
  • New frame design sheds 300-grams over previous 429 SL
  • DT Swiss hoops with 36-tooth hubs engage nearly instantly
  • Lightweight carbon frame offers stiff control, and a 10-year warranty
  • SRAM X01 drivetrain for slick and precise shifts, endless gears

I’m interested in the Pivot Mach 4 SL but do not know what size will fit me best. I am 67” tall with a 31” inseam. Please let me know what size I should get. Thank you.

Hi Ron, Excellent question, according to Pivot bikes recommendation chart you be on a size small. Small: 5'4" – 5’8” Keep in mind that this is a recommendation and that your preferences and riding style can also factor into what size bike you may prefer. You can reach out to me directly at 801-204-4671 if you have any questions.

Light Weight Trail Bike

Familiarity:
I've put it through the wringer

If you have never owned a Pivot, they pedal amazing well and this one is no different. The suspension is firm as should be expected but still absorbs the roots and rocks just fine. I was on the line between a small and medium. The small was a great choice since the wheelbase is similar to the Mach 4 Carbon it replaced. It handles the tight Ohio trails just fine. Don't box this bike into the race category though, it performs very well as a light weight trail bike. It's primary limitation is only the tires if you want to go into BRRAAP mode. FWIW, my build weight with pedals, Wahoo and Aspen tires is 25.06 lbs. EDventure

Dirt Fitness

Familiarity:
I've used it once or twice and have initial impressions

I took this bike out for a big day here in the Wasatch Mountains of Salt Lake City, Utah. Kitted out, this bike matched not only my lycra attire but my inner ethos focused on speed, fitness, and fun. On the uphill, this bike pedaled better than any bike I have ridden. While a hardtail may be fast, the suspension on this bike makes it compliant on the uphill tracking over roots, bumps and rocks to provide a faster xc bike. At the top, I was curious how this bike would shred. Loads of flannel wearing, goggle donning enduro riders were shuttling the ride I had just ridden up and I pointed the bike down and just shot it. Like skiing powder in the winter, I felt like I was surfing through turns, in and out of pristine mountain single track. Launching of roots and rocks, the bike allowed finesse that a bigger traveled bike would have dampened. In short, I loved the way it rode uphill, but couldn't believe the way it was going down. For the riding I like to do, which is a combo of being fast and fun, this is the bike for me.

Impressive

Familiarity:
I've used it once or twice and have initial impressions

The past 24 months have been good for XC bikes. With the release of the new Santa Cruz Blur, Yeti SB100, Intense Sniper, Trek Topfuel, and Specialized Epic, it's become abundantly clear that the lycra-inclined among us are ready to throw down the gauntlet and face up to a gnarlier, rougher, more rad XC reality. The Mach 4SL's DW-link suspension is its party piece. This bike pedals better than the Blur or the SB100, and it impressed on the way down as well. Pivot's DW bikes truly do not exhibit brake jack! Compared to the Blur, the 4SL was slightly less predictable on rough descents, but it was extremely impressive in low-speed technical sections. I'd have to give the Blur/SB100 the advantage when it comes to descending, but the 4SL is definitely more efficient. Please reach out directly if you have any questions!

With ability to ride many different bikes, do you still think the Mach 4 is the best super light and quick trail bike on the market? I live between the Appalachia mountains and the Atlantic Ocean. I have multiple types of terrain and trails, including rock gardens. I do not want a too long and too low bike that eats pedals and cranksets, unless I spend more MONEY on a new short crankset. Thank you.

I can't comment on this bike specifically, but Pivots don't tend to have an ultra low BB heights. I have a Trail429 for reference and there is a hi/low geometry setting . Pour over the geo charts online, and buy crank boots like race face or AMS for protection. Also pedal choice xc type clips have a small surface area and are less likely to get hung up. If you ride flats go for quality plastic pedals, like Deity Deftraps, One Up, etc.. as they slid over rocks better than metal. You can even remove the outer pins for more slide. Hope this helps. I grew up riding the east coast so I know there terrain you're talking about. Cheers

Gearhead I am ditching my old bikes, Truck and Cannondale, as they have seen better days. I am looking at the Pivot Trail 429 Pro XT/XTR. How would you say this bike, the Pivot Mach 4 listed above compares. I am primarily riding Trails with plenty of vertical but I will not be in rock gardens or making big jumps as I am getting older. I do however, want a very capable bike. Thanks
