Unknown Singularity Silver | Fixed Gear & Single Speed Bike

The Unknown Singularity Silver is the evolution of the legendary LV2 frame, redesigned from the ground up as a complete race-ready fixed gear bike. The clean silver finish gives this bike a timeless, head-turning look that works on the track and the streets. Built around a hardened 6066-T6 aluminum frame with updated track geometry and an integrated aero seatpost, the Singularity delivers serious performance at just 7.5kg in size M.

Every component is designed by Unknown for fixed gear riding. The carbon/alloy fork with 12K carbon blades and aluminum neck provides sharp steering and vibration dampening — a significant upgrade over standard alloy forks. The sealed-bearing Mushroom hub wheelset with Japanese bearings rolls smooth and fast, while the 46t/17t gearing gives you an ideal ratio for urban riding and track sessions.

Slouch Master!
Size: One Size, Color: Black, Size: One Size, Color: Black
The size of the bag, the two pockets big enough to fit my phone, and the silver hardware are what sold me. But oh, the slouch is top tier. It's fitting my large coach wallet, nolita 19, and a small baggu pouch with plenty of extra room. It came factory wrapped and shipped overnight. I added carabiners to attach my chains, but if Kate Spade added small charm rings at each end it would be even better.

She’s pretty and elegant looking
Size: One Size, Color: Crinkle Morning Beach, Size: One Size, Color: Crinkle Morning Beach
I need to start this with starting I am a huge fan an all Kate Spade products and have never had any issues with there merchandise. I have never spent the amount they are charging for this and honestly can’t say it seems reasonable however the bag is really pretty. The material is thick, solid, soft, leather like meant to last. It is a big purse and you can carry quite a bit, only has a couple inside pockets so it’s more of a throw everything inside bag with little to no organization which is not my personal favorite. However when you are a mom always on the go and don’t want the hassle of a smaller purse you have to straighten up all the time, this is the choice for you. It does look exactly like the picture and you only have the option of the short handle which again doesn’t bother me in the least as it does fit on my shoulder perfectly.

Elegant, High-Quality Purse Perfect for Formal Events
Size: One Size, Color: Black
This is a large shoulder bag that ends up being the perfect size for a weekend outing or a nicer evening event. It’s made from genuine leather, and you can immediately tell from how soft it feels while still holding its shape really well. The design is very clean and elegant. There aren’t bulky outside pockets or extra zippers, so it has a sleek look that works great for dressing up. The black leather is deep and flawless, and the gold accents add a really classy touch. Inside, there aren’t a ton of compartments, so it’s more of a “throw everything in” type of purse. Thankfully, it’s roomy enough to comfortably fit a phone, wallet, keys, makeup, and pretty much anything else needed for a night out. It probably isn’t specifically intended for everyday use, although it definitely could be used that way. It also comes with a storage bag, which is nice for keeping it protected in a closet between events. For cleaning, I’d recommend using a proper leather handbag cleaner and avoiding harsh chemicals or wipes since it’s genuine leather. My wife has gotten a lot of compliments on it because it looks beautiful and elegant, and she loves using it for nicer occasions. I’d highly recommend it for formal events or nights out.
