Experience trail riding the way it was meant to be — with a bike that balances nimble climbing, confident descending, and trail-ready durability. The Portal C4 delivers the performance and value you expect from a modern full-suspension trail bike, wrapped in a light, high-modulus carbon frame that’s built to take on Utah’s toughest terrain.

Key Features & Component Highlights

  • Frame & Suspension: Dyad Pro high-modulus carbon fiber frame paired with Jamis’s proprietary 3VO suspension platform. 130 mm of travel gives the sweet spot of efficiency for climbs and compliance on descents. The 3VO linkage delivers a responsive yet stable ride by keeping chain-line and leverage ratio optimized throughout the travel. 

  • Fork & Shock: Front suspension handled by a Fox 34 Rhythm Float 29″ fork with 130 mm travel, air spring, sweep-adjust compression, lock-out and rebound adjust for precise control. Rear suspension is managed by a Fox Float DPS Performance Series EVOL shock with 3-position compression, offering a smooth, active rear end on varied terrain. 

  • Drivetrain & Gearing: 1×12-speed drivetrain built around a Shimano Deore groupset — including shifter and rear derailleur — for reliable, wide-range shifting. A 32T Race Face Ride crank and a Shimano M6100 12-speed cassette (10–51T) give you the range you need for steep climbs and fast descents. Chain is a KMC X12 12-speed. 

  • Brakes: Hydraulic disc brakes from Shimano (MT420, 4-piston), with 180 mm front and 160 mm rear rotors for consistent stopping power even on steep, technical terrain.

  • Wheels & Tires: Stans NoTubes Flow D 29″ rims, laced to Shimano MT410 hubs (15×110 mm front, 12×148 mm rear), shod with Vittoria Mazza 29″ × 2.4″ TNT tubeless-ready tires for excellent grip and rolling efficiency. 

  • Cockpit & Comfort: Race Face Ride 760 mm handlebar with 20 mm rise and a 50 mm Race Face stem give stable and responsive handling. A KS Rage dropper seatpost with Southpaw remote justifies any trail-side line choice. Saddle is a WTB Volt, and grips are Jamis Lock-On style. 

  • Build Purpose: Portal C4 is designed as a do-everything trail bike — light enough to climb efficiently, yet capable enough to tackle technical descents, making it a true do-it-all package for trail riders who want a single bike for most of their rides. 

Why Portal C4 is a Great Fit

If you’re a trail rider looking for a confident, capable bike — whether you’re doing big climbs in the Wasatch, ripping technical descents, or shredding local trails — the Portal C4 offers exceptional value, balanced performance, and trustworthy components. The carbon-fiber 3VO chassis keeps your ride lively and efficient, while the Fox suspension and Shimano drivetrain/brakes give premium-level reliability and performance without overpaying for hype.

Great Value and Very Durable Plates
Color: Brown, Size: 10 in - 75 count
These plates are a great value for the price considering the quantity and the quality you get. Getting 75 plates at this price point is already a win, but the durability makes them even better. They’re biodegradable, which is a nice bonus, and they’re definitely not flimsy. These plates are stiff and sturdy — I can load them up with a pretty heavy plate of food and they still hold up without bending. They also do really well in the microwave, which makes them even more convenient for everyday use or parties. Overall, a really solid disposable plate option that’s durable, eco-friendly, and a great value.

A bit iffy on these plates
Color: Brown, Size: 9 in - 75 count, Color: Brown, Size: 9 in - 75 count
These plates are ok, but certainly not the best I've found. On the positive side, they are what I'd consider "Lunch Size" an are somewhat sturdy. They'll hold a sandwich and chips with little effort so, as a plate, they do... plate. Where I am a bit hesitant is in their molding an construction. You can see in my photos that there is significant staining/watermarking on the plates from the manufacturing process. This could be simply from the way the wet pulp was extruded and formed, but it honestly gives me a bit of the ick. Not that it's particularly gross, but it does make me wonder how sanitary the plates are or what binders might be leeching into my food. In my last photo, you can see a comparison to a compostable plate that I really like. The finish is cleaner and the mold included an inner ridge which gives the plate more stability - making it less likely to flex under weight. Both are sugar cane fiber plates and my preferred plate is a few dollars more expensive for a comparable pack, but the clean appearance and extra rigidity make it worth the added spend in my opinion. Ranking these 3-stars might lead some to think they're bad - and to be clear, I don't think they are. They're just adequate. If you're looking to save a few bucks on a compostable plate, these WILL get the job done. I would just shy away from using them with wet or acidic foods since they don't boast the highest quality of manufacture.

Strong Eco Friendly Plates But Not Great For Hot Food
Color: Brown, Size: 9 in - 75 count
I picked these up because I wanted something more environmentally friendly than the usual plastic or paper stuff. They are made from bamboo and bagasse, and you get a good amount in the pack for the price. For dry stuff like snacks or sandwiches, they are super sturdy and do not bend at all when you pick them up. However, they do not hold up very well when you put hot or wet food on them. Even though they are supposed to be heavy duty, I noticed they can get a little soft if the food is really steaming. They are still perfect for a quick lunch or a party where you want an easy cleanup, but you might want to double them up if you are serving something heavy and hot. The plates are big, and you get quite a bit, making it a really good value overall.

Heavy duty paper plates
Color: Brown, Size: 10 in - 75 count
These disposable plates are amazing. They're large enough to hold an entire Thanksgiving meal. They're sturdy and strong, and won't buckle even when supporting quite a lot of weight. They don't get soggy even when I deliberately poured water in them. The sides are built up to keep food from falling off the plate. These are everything you'd need in a disposable plate, and they're biodegradable, too! These are ideal for barbeques or outdoor entertaining, or even for everyday use in the kitchen.

Compostable Paper Plates
Color: Brown, Size: 9 in - 75 count
I ordered these because I like using paper plates and wanted to see if the compostable ones were strong enough for regular use. They're sturdier than regular paper plates due to the increased thickness of these. I've put heavy food on them like ribs and sides and they haven't bent under the weight. They feel more like pressed cardboard than paper and hold up through a full meal without getting soft. The brown color is a little utilitarian looking but that doesn't really matter for what they are. I guess I wouldn't use them for a party or something fun like that. They stack neatly and take up about the same space as regular paper plates.
