Jon J's Bio

I grew up on Colorado's Front Range, and have now spent extended time in Wyoming and Utah as well. Salt Lakes 4K elevation is the lowest I've ever lived at.
After me knees had had enough of running competitively in college, I transitioned to XC mtn bike racing. A great cardiovascular system and lower leg strength made the transition very easy. Now a days with a family I race less, but like to get out for a ride any chance I get. I'm the Yeti Cycles brand ambassador here at Competitive, and have ridden Yeti's for 10 years now. I'm currently loving my SB95c and am happy to answer any questions regarding all things Yeti.

Familiarity: I've put it through the wringer

The Wahoo Kickr SNAP is just that, a snap to setup and get riding. Throw a trainer tire on your wheel, tighten the blue knob until the tire doens't slip on the drum, and turn on your devices Blue Tooth connection, or ANT+ dongle. Start pedaling, connect the trainer in the software of your choice, and commence increasing your watts. I paired mine to an Ipad Mini, and tried a number of apps to get a feel for each. The SNAP give a realistic road feel, and is quiet enough that my sleeping 1 year old in the next room never woke up. The only danger is with trainers like the Snap, and apps like Zwift, Trainer Road, and the like, your road bike may have found a new permanent home.

Familiarity: I've put it through the wringer

After spinning in circles forever, I put an oval ring on when my last Cinch ring finally wore out. I'd always run a 30T roung ring, and decided to go up to a 32T oval. I didn't, and still don't, notice any difference in the pedal stroke feel. What I did notice was more effort when I rode a demo bike with a 32T round ring and the same Eagle X01 drive-train.

I decided to give an oval ring a try, and while I was at it decided to try OneUp's Switch System. I've been impressed thus far, with both the ring and the system. I greases all the bolts when installing the ring, and haven't had any creaking, which was an initial fear. The ring/system looks really clean, and has work flawlessly with my Eagle X01 drivetrain.

Let 'er rip

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

I was able to hop on the new Mach 6 for a day at Outberbike this fall. Having had the first iteration of the Mach 6 3 years ago, it was nice to compare. The new bike is certainly longer and lower. I rode a small for both, but the new bike had a 40mm stem and felt good, whereas the first mach 6 had a 70mm stem and still left me pretty upright. I'm 5'8", and have always been able to ride either a small or medium for most frames. I rode the medium Mach 5.5 comfortably and would imagine the Mach 6 would have been fine as well, but I wan't uncomfortable riding the size small for 20+miles. The bike is really at home on wide open, fast, rocky descents, where you can stay off the brakes and hold on. On tighter technical climbs, especially switchbacks, the bike did require more steering input, and I can only imagine that would have been more noticeable on the longer medium vs the small. While more at home when the trails points downhill, the Mach 6 still pedals with the efficiency accustomed to the DW linkage.
Before the Mach 6 was released, I thought it had been replaced with the new Mach 5.5, and on paper the bikes look very similar, but those small differences do come to life on the trail. I would give the nod to the Mach 6 if you're riding big chunky terrain and are looking for speed on the descent above all else. If you're planning a big day in the saddle with as much up as down, the Mach 5.5 is probably your huckleberry. In any case, you can't go wrong with either of the new offerings from Pivot.
Please don't hesitate to contact me directly if you have nay questions on the Mach 6, or any of the bikes we offer

I'd call the 5010 Santa Cruz's 27.5 wheeled Swiss army knife. Capable of toeing the line of a weekly XC series, but also more than happy to ride the lift for park laps. Santa Cruz calls it "a bike handlers bike", and it's short wheelbase and tight geo give it a lively and playful feel on the trail. It happily boosts off the smallest rock or root, and rails the corners. My only qualm coming from a 29er was the extra effort needed to get the smaller wheels up to speed once the trail pointed downhill. Let me know if you have any questions about the 5010 and how if compares to other offerings in Santa Cruz's range, or those of other manufacturers.

Bomber Upgrade
5 5

I've been running these wheels for a few months, and they've been fantastic. I have Enve's on my other bike, and I can't say I notice the difference when riding in engagement between the 52 tooth star ratchet of the 240 hub and the 4 pawl engagement of Mercury. If you're looking at a Stans Arch wheel, or a Trail S, I'd take a look at the X1s. I've had carbon wheels on my bikes for the past 5 years, and have had zero durability problems, whereas the one alloy set I've had in that time ended up getting a dent in the rim. The Mercurys are hand built in Ogden, and I have yet to have any reason to look at another option.

Best of the best

Familiarity: I've put it through the wringer

I've had a number of helmets in my time with Competitive from Bell, Giro, Fox, and Kali, all have kept my senses intact. The Tectal is the one that fit best, topped in style points, and breathed the most. I've got a slightly oblong shaped head, and the Tectal fits it perfectly. The large venting keeps things cool, and I haven't had any issues with the easy adjustable retention dial. My one small gripe is the visor adjustment screw. At fist it would come loose and even fell out once, thankfully in my gear bag. I took some need nose pliers, and cranked it down tight, and haven't had an issue since.

I’ve been at Competitive for 5 years, and in that time, I’ve changed bikes after each year. The SB45 is the bike hat has bucked that trend. From XC/Endurance racing, to trips to Moab, this bike’s versatility is boundless. Anchored by Yeti’s Switch Infinity suspension platform, which provides excellent small bump compliance and a progressive mid stroke, I have yet to feel a harsh bottom out on this bike. Add to that the unparalleled pedaling performance, and you have in my opinion the best suspension platform in the industry. Personally, I’m the one holding this bike back when things get really rowdy. Are there other bike that have more of a “hold on and stay off the brakes” mentality, sure, it’s the 4.5’s big brother the 5.5, but I’ve ridden that also, and felt that it was overkill for the majority of trails I ride day in day out. Yeti wraps all that into a frame with progressive geometry, clean internal routing, and great visual lines.
My bike with carbon wheels, X01 drivetrain, and a Fox dropper tips the scales at 26.5 pounds with pedals. If you’re looking for a bike that can rip the local descent, and hold its own at the town XC race, the SB45 fits the bill.

I was surprised to find how comfortable the Stratos was for me. My go to saddle is a Selle Italia SLR, and have always been comfortable on similar, flatter profile saddles, like the WYB Volt on an MTB. When I mounted the Stratos on my bike, even without fin tuning for and aft positioning, and eyeballing the level, it was just comfortable. The Stratos is the "medium" padded saddle in the "narrower" line of SMPs saddles incuding the Composit, Evolution, Blaster, and Glider. This is the family SMP recommends for riders whose body frame generally matches the small/medium size in bibs,

Coming from Guide RSCs, I knew the 2 piston feel of the Levels would be different, but I'm really enjoying that difference. At 145lbs, I don't need tons of braking power. I didn't feel like the Guides were grabby, but the Levels feel much smoother in their modulation.

Really wanted these glasses to work out, but the bridge of my nose just didn't agree with the adjustable nose pads. I'd say I have a medium to small sized face, and coverage of the lens was good, didn't look too big on my face, and didn't have a large gap between my temple and the frame.

Fun +
5 5

Familiarity: I've used it several times

I was able to put the SB5+ through the paces for 3 days during a trip to Summit County, CO this fall. I've had the SB5 in the past, and presently have SB4.5 in the garage, so it's safe to say I'm a disciple of the Switch Infinity linkage suspension. The SB5+ follows in the same vein as the other bike of the SB lineup with incredible pedaling efficiency and power transfer paired with a supple, bottomless, feel once things get pointed downhill.
I didn't have a scale with me, I'd put the Yeti'™s claimed weight of 28lbs without pedals as being pretty accurate. My SB45 weights 26.5 with Enve wheels/pedals, and the SB5+ didn't feel much heavier in hand, or riding on the trail. The benefits of plus tires proved true, with confidence inspiring grip in loose conditions, and forgiving float over chunk rock gardens. I was tentative about flatting, so I ran what I felt was a higher than normal pressure of 15/16 PSI F/R for my 140lb frame, and had no punctures to speak of, so credit to the Maxxis Rekons there. My biggest day was a ride over the Ten Mile Range from Copper Mtn ski area into the town of Frisco. Going up, the plus tires had grip for days, and if I had the capacity to turn the pedals, the bike would have kept going, but damn did it get steep! Once on top, and coming down through the scree and roots and rocks, the SB5+ only inspired more and more confidence.
The last day I decided to experiment, and moved my 29" Enve M60 boost wheels onto the SB5+, clearance was a non-issue on both the rear triangle, and the 27.5+ Boost Fox fork (photo'™d below). Ride wise the bikes geo wasn't adversely affected, and I didn'™t notice and difference in steering or feel. The most noticeable thing was the reduced wheel weight going from an alloy 27.5+ setup to a carbon 29" setup with 2.35 tires. I charged down the last part of the descent I had ridden the previous day on the 27.5+ wheels with the same confidence and speed. BB height on the stock SB5+ is on the lower end at 13", and I did notice more rock strikes initially, but never felt it was a constant problem. Overall I came away very impressed with the SB5+, I don't race regularly any longer, but still like a fast, capable bike. Should the occasional race pop up, I'd have no problem calling the 29" wheels into duty.

The G4 cranks raise the game. While only shedding 15g over the previous SLs, the G4 crank arms are stiffer and have a much improved aesthetic in my opinion. While increased stiffness is tough to evaluate on the bike, these are noticeably stiffer under offset load than the new Eagle X01 cranks. The cranks include a set of black crank boots to keep things tidy. At release, RaceFace also had a carbon spidered chainring, however those have been tabled for the time being.

Used this in a recent 24hr race between laps, and it did the trick. Doing a hard lap every 3 hours on our four man team, I never had that "race gut" feeling. The vanilla mix tastes like a melted milkshake, and isn't a chalky consistency like other recovery mixes I've tried in the past. Great to mix up in bottle for the ride home from a hard effort!
