Splitfire:
Everything Bigger

The Splitfire is a titanium gravel bike built for riders who want more room, more speed, and more versatility from one frame. With clearance for up to 700 x 57mm tires, short 419mm chainstays, UDH compatibility, and clearance for oversized chainrings, Splitfire blends backcountry capability with fast-gravel efficiency.

57mm Maximum listed 700c tire clearance for rough gravel, mixed terrain, and adventure setups.
419mm Short chainstays keep the bike lively and responsive despite the massive tire clearance.
45/50 Adjustable fork offset options allow riders to tune trail and steering feel.
Tire Clearance

700 x 57mm or 29 x 2.25 capability.

Splitfire was created for riders who want the freedom to run big, confidence-inspiring tires without giving up the speed and fit of a performance gravel bike. Larger tires add comfort, traction, and stability on rough roads, loose gravel, and long backcountry routes.

More Traction A larger contact patch improves grip on loose, wet, and uneven surfaces.
More Comfort Higher tire volume allows lower pressure and helps reduce fatigue on long rides.
More Control Big tires add stability when descending, cornering, and riding loaded.
More Versatility Run fast gravel tires, monster-cross tires, or bikepacking-ready setups.
Why Splitfire Exists

Short stays. Big tires. Big chainrings.

The elevated driveside chainstay gives the Splitfire its defining advantage: room for large tires and large chainrings while keeping the rear end compact. That combination makes it equally at home on fast gravel rides, rough mixed-surface routes, and road-wheel swaps.

Elevated Chainstay

The driveside E-stay opens space at the tire and chainring junction, allowing a rare mix of tire volume, gearing clearance, and short chainstay handling.

UDH Compatible

A modern universal derailleur hanger platform simplifies replacement, improves drivetrain compatibility, and keeps the frame ready for current and future drivetrain standards.

T47 Threaded BB

The T47 threaded bottom bracket combines the serviceability of a threaded system with a larger shell diameter for stiffness, alignment, bearing support, and easy maintenance.

Geometry

Progressive gravel fit with tunable handling.

Splitfire geometry is designed around stability at speed, responsive acceleration, and multiple tire configurations. The result is a titanium gravel platform that can be built for fast mixed-surface riding, rough gravel, or long-distance adventure use.

Adorable toddler jacket
Size: 18 Months, Color: Stone Medium Wash, Size: 18 Months, Color: Stone Medium Wash
I love this little jean jacket! It's a really good quality denim, thick and weighted with a soft lining. I washed and dried it in the dryer without notable shrinkage, but the denim did fade slightly around the cuffs and seems (photos after washing). I like the look it gave though. It feels very durable and high quality for the price. It is an oversized fit. I got size 18 months and it runs large with a loose and long fit. It's very cute on my toddler though and goes with everything so a very versatile piece! I would say it's a medium to light weight/temp jacket great for spring, summer and fall. Overall, I would purchase again! I think I'm going to embroider some flowers on it, great base jacket for that!

Comfortable and lightweight
Size: 2T, Color: Stone Light Wash, Size: 2T, Color: Stone Light Wash
I purchased the **Amazon Essentials soft stretch denim jacket** for my baby/toddler, and overall it’s a **cute and practical layering piece**, especially for the price. **What I liked:** The jacket has a classic denim look that goes with almost anything—jeans, leggings, dresses, or even over a onesie. The **stone wash color** is versatile and gives it a slightly vintage style. The denim has a bit of **stretch in the fabric**, which helps make it more comfortable for babies and toddlers who are constantly moving. Many denim jackets can feel stiff, but this one is softer and easier for little ones to wear. The **regular-fit design** gives enough room for layering over shirts or light sweaters without feeling too tight. It’s also lightweight enough for spring or fall weather, making it a good everyday jacket rather than a heavy coat. **What could be better:** The material is a bit **thinner than traditional denim jackets**, which is nice for comfort but means it won’t provide much warmth in colder temperatures. It works best as a light outer layer rather than a winter jacket. Sizing can also vary slightly. Some parents find that the sleeves run a little long on smaller babies, so it may require rolling the cuffs at first. **Overall:** The Amazon Essentials baby denim jacket is a **stylish, affordable option for everyday wear**. It’s comfortable, easy to pair with different outfits, and flexible enough for active babies and toddlers. While it’s not the thickest denim and may run slightly big, it’s still a great value if you’re looking for a simple, cute jacket for your little one. ⭐ **Overall rating:** 4/5 – Cute, comfortable, and budget-friendly, but lighter weight than a traditional denim jacket.
