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.

1 year review from a teleworker
Color: Grey
I purchased the Homall Office Chair in March of 2022, with high expectations of comfort and functionality. I liked how the chair looked, its price point, and it received positive reviews. Unfortunately, my experience with this chair has been underwhelming, to say the least. Several issues, ranging from poor quality to difficult assembly, have left me deeply dissatisfied with my purchase.
Let's start with the assembly process, which was an absolute nightmare. The instructions provided were not terrible, but not great either. It took me significantly longer than anticipated to assemble this chair, and I consider myself fairly handy. If you're not well-versed in putting together furniture, you may find yourself extremely frustrated.
Another significant issue I encountered was with the chair's hydraulic cylinder. It has already started failing, causing the chair to slowly sink, regardless of the adjustment settings. This rendered the height adjustment feature useless and made for an uncomfortable seating position. I expected a durable and reliable chair, but sadly, this was not the case.
The armrests were also a major disappointment. They started to deform and indent where my elbows and arms sit. The rest of the chair is fine. I can sit it in all day, so that is a positive. I mainly lean a bit forward and don't have time to lounge backward.
On top of all these issues, the Homall Office Chair proved to be quite noisy. Whenever I shifted my weight or made any slight movements, the chair emitted creaking and squeaking sounds. Not only was it an annoyance, but it also disrupted my concentration while working and is embarrassing on conference calls. Having such a distracting and low-quality chair in a professional environment is disappointing.
If I read this review I would have a couple of questions about the reviewer. I am 6'3" but well below the recommended weight. I review plans and specs as part of my job, so I am good with instructions. My hobby is woodworking which requires skill and a calm demeanor. Yes, I did retighten any connectors that became loose through normal wear and tear.
I should have spent more money on a quality chair since I am now looking to purchase a different chair 1 year later. I would advise others to take that into consideration. Spend a little more and keep less junk out of our landfills.

High Quality Rolling Chair
Color: Black/Silver
My son LOVES this desk chair. He has a drafting table to draw and do schoolwork on, and this provides him a comfortable chair to work in. It is sturdy and easy to clean. It does not fold, but it does roll easily. It was VERY EASY to put together. We were also pleased with the price. He will be able to use it for years to come.

The Greatest Chair I've Ever Sat In
Color: Black/Silver, Color: Black/Silver
When I was a boy, my first office chair that I used for PC and laptop work growing up was this chair. This was back before 2010 so it likely wasn't under the Amazon Basics brand but it was the exact same chair design. I've used that chair my entire life really and only had to buy this chair as a replacement as the leather started peeling significantly on my old chair after over 20 years of use. Even though the leather was heavily peeled, my old chair was still extremely comfortable and I would've kept on using it had I not gotten annoyed with having to pick up leather bits and pieces everyday from the peeling. I bought this chair as a replacement and the comfort is still as I remembered. No lower back pain, no butt numbness, no arm numbness, truly such a masterpiece of a chair where it lets you focus on the task at hand instead of focusing on the chair. Before I rebought this chair, I've bought & tried the Secretlab Titan Evo Nanogen, Furmax executive office chair, Neo executive office chair, RS high back gaming chair w/ flip-up armrests, Bestfair high-back office chair, FDW executive office chair, Herman Miller Aeron, and OFIKA executive office chair in search of a potential "upgrade" - every single one of these other chairs was inferior to the Amazon Basics high back office chair in one way or the other. The only thing I will note is that the pneumatic gas cylinder of the Amazon Basics office chair seems to be different from my original chair - it goes higher and has a higher minimum seat height. If you would like to perfectly replicate the original lower seat depth you will have to buy the S6124 extra short office chair gas lift cylinder from ChairPartsOnline - my only nitpick about such a phenomenal chair. In my attached picture I have the Amazon Basics chair w/ S6124 gas cylinder on the right next to the Furmax high-back office chair which although inferior is what I consider to be the 2nd best chair if for some reason you cannot get the Amazon Basics high-back office chair. To sum it up - I HIGHLY RECOMMEND THIS CHAIR!!!

Comfortable Office Chair
Color: Black/Silver
I have had several office chairs here in my office. Even though this office chair was a bit difficult to assemble, it appears to be a quality item. I was NOT impressed with the instructions - at all. More specific instructions would have been nice. Only time will tell if this was a good purchase and this chair is a good value. Not a bad price for the item as well.

All-around good chair, suitable for me at 6'6", comfortable and no issues
Pros:
The assembly is straightforward and doesn't require much strength; I would expect my mother to have no issue putting this chair together. If you're elderly or disabled, a relative or helper should have an easy and quick time of putting it together, and there is very little chance of making a mistake during assembly.
Sturdy at and slightly above the recommended weight limit. I peaked around 256 or 258lbs while using this chair, and it didn't show any signs of complaint then, and it hasn't shown signs of wear since.
Really comfortable. I'm an eight-hours-a-day user, almost without exception, and I have no complaints.
The leather holds up very well. I don't expect this to be true forever, but after approximately 1800 hours of use, there is no tear or warning sign.
It leans back super stably. That's the most important aspect for me.
It's tall enough to support my 6'6" frame. My back rests comfortably, so the odds are yours will fit, too. For the scary few who tower over me, and so you can search it easily, here's a height guide:
6'3" 6'4" 6'5" - The chair is good for your heights
6'7" - You should also be well served, unless your height is mostly in your torso.
6'8" - You're at the cusp. I think you will be comfortable in this chair, and alternatives that are built for our (mostly your) height cost so much more. I'd give it a try. I wish you luck.
6'9" 6'10" 6'11" - This is written for 6'9. For 6'10, 6'11, scale the significance of the caution. I think this chair will prove uncomfortable for you or encourage bad posture. I'd encourage you to look elsewhere.
Cons:
This is well covered in other reviews: the caps that cover up the screws on the side of the arms are poorly designed. One falls off every day or two. It's a minor inconvenience, but it's optional. You can toss the caps in the trash. The screws are not exposed. They sit deep within the plastic of the arm. Personally, I just push the covers back on when I notice they fell.
The armrests could be better for me, I think. I'm not sure exactly what my complaint is. I think they are a little too narrow for my liking, but I'm 6'6" with broad shoulders and long arms and unusual joints. The spacing seems fine for a typical user.
Notes:
I only sit leaning the chair back or sitting up straight at the edge of my seat. Some aspects of this review may not translate perfectly to locked-in-place, sitting back, upright usage.
