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.

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.

Familiarity: I've put it through the wringer

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.

Familiarity: I returned this product before using it

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!

I've been on my M60's since March, and they continue to amaze. Their reliability and durability is without questions. My use has been more like abuse of these.

Ridden 3 miles down on a flat tire, check (FYI - You'll want to carry a 48mm stemmed tube.

Charged wantonly into rock fields at questionable speeds - check.

Run sub 20 PSI in both tires - check.

Hear the aching "thung" of carbon on rock in the 2nd of 7 laps of a 24hr race, and ride the ensuing 5 with a hop in the wheel with out issue - check

Previous alloy wheels I've owned would have failed long ago under the same abuse these Enves have withstood.

Get pumped
5 5

Familiarity: I've put it through the wringer

If your garage is full of mountain bikes, make room for the Chamber HV pump. Gone are my days of guesstimating pressure around the 20PSI line. The Chambers massive dial, and individual PSI marks make setting exact pressures a cinch. If there was any flaw in the pump, its that the dial going up to 50 PSI was too much, they could have easily stopped at 30-35 PSI for modern mountain tires, even that might be on the high end. The unit as a whole is solid and stable. The metal base keeps it upright without issue, and the hose is plenty long, and has a good clip to keep it wrapped around the pump when not in use. I can easily reach valve stems with my bike in the stand. The machined handle is bolted on with the same 31.6 clamp of a handlebar. In the future maybe I'll put some cut down bars and grips on it for a personal touch.

I've really been impressed with my X-Project 1s. The carbon sole is stiff where you need it for pedaling, but has a noticeable flex when you're walking or have to hike-a-bike. The BOA provides an even, snug fit, and doesn't loosen like some velcro straps will over time.
I would call the fit true to size. I have the same 41 as I've worn in every other shoe I've had, that being said, I do have a hair less room in front of my toe compared to my Giros, but I chalk that up to personal preference. My pair of 41s with crank bros cleats weighs in at 700 grams for the pair.

Mount Up!
4 5

Familiarity: I've used it several times

RockyMounts brings a solid contender to the hitch mounted rack field. I've previously owned the Yakima HoldUp, and have used a buddy's Kuat NV quite a bit. The Splitrail is on par with both of those. Though having a claimed weight of 44lbs for the 2in receiver option, the rack feels lighter, and more balanced than the HoldUp which claims to be 39lbs.
It took me 30 minutes to install the Splitrail, and assembly is very straightforward and easy with the included hex wrenches. The hitch's fir system creates a very stable interface, with no wobble, but can be in issue if you're moving the rack from one car to another regularly. The rear handle for adjusting the position of the rack is also a strong point. The rack has ample clearance for 29 and 27+ tires. Though RockyMounts doesn't recommend it, I was bale to fit my fatbike with 4.8 tires onto the rack with a ski strap, but do so at my own peril.
The locking system is a weak point in my opinion compared to other offering. A cable extends from the arms, and a metal chuck locks into the end of the cable creating a loop. No rack's included lock/cable is very substantial, they're all there to keep people honest, but the Splitrail's system limits where you can loop the cable. If I were leaving bikes on the rack during an extended period of time, I'd use a thicker cable looped through the hitch like I have with my HoldUp.
Overall the Splitrail is a great rack, that's easy to use, and will get you and your bike to and from the trail with ease.

Teller on the Mountain

Familiarity: I've put it through the wringer

I pretty much lived in these shorts on our last trip to Moab. I've got 2 pairs, a small and medium. My waist is 31", and the smalls fit fine, and the mediums are a little big, but leave better length for use with knee pads. They also have an internal cinch at the wast. The front zip pockets keep anything safe when you're on the bike, and are great for keeping stuff organized pre and post ride. A velcro rear pocket also comes in handy for day to day use. I've even left my wallet back there on a ride and did notice it until I got back to the car.
