Blackwater Bicycles / Custom Titanium Gravel

3 Notch:
The Blank Canvas

The 3 Notch is where your ideas take form — a titanium gravel platform engineered to be shaped entirely around you. Start with one of our proven stock geometries, then tune the details for your terrain, your fit, your riding style, and the bike you have always wanted to build.

Custom Geometry, fit, mounting options, routing, and ride character can be shaped around your exact needs.
415mm Updated stock chainstay length keeps the platform responsive while leaving room for real gravel setups.
395mm Modern gravel fork axle-to-crown standard for confident handling and larger tire compatibility.
Yours Built as a one-of-a-kind Blackwater machine, not a stock frame with a few small options.
Blank Canvas Platform

Start with a proven shape. Make it entirely yours.

The 3 Notch starts as a clean titanium foundation, then becomes whatever you need it to be. Build it as a fast gravel racer, a long-distance all-road bike, a fully loaded bikepacking rig, or something completely your own.

Geometry, tire clearance, mounts, routing, finish, and component fit can all be tuned around the way you ride and the landscapes you chase.

Fit-Tuned Choose a stock size or adjust reach, stack, angles, and contact points for your exact body position.
Terrain-Tuned Design the frame around fast gravel, mixed roads, bikepacking, chunky terrain, or all-day adventure.
Build-Tuned Plan tire clearance, drivetrain choice, mounts, routing, and cockpit setup before the frame is made.
Purpose-Built A ground-up custom titanium build shaped around your ride, not someone else’s stock idea.
How It Works

Your dream bike starts with the details.

Pick from one of the stock geometries below, then decide what should stay, what should change, and what needs to be built around your riding style.

1. Choose a Base Size Start with the closest stock fit from Extra Small through Extra Large.
2. Tune the Numbers Adjust geometry, tire clearance, handling, mounts, and fit details.
3. Pick the Build Select drivetrain, wheels, cockpit, fork, finish, and custom features.
4. Make It Yours The result is a one-of-a-kind Blackwater built around your vision.
Why 3 Notch Exists

Not a stock frame. A starting point.

The 3 Notch is for riders who know a bike should match the person riding it. Instead of forcing your fit, terrain, and goals into a fixed production frame, 3 Notch gives you a proven titanium platform that can be shaped into the bike you actually want.

Custom Geometry

Start from a stock size or tune reach, stack, angles, chainstay length, bottom bracket drop, and fit numbers to match your riding position.

Custom Features

Add the mounts, routing, tire clearance, drivetrain compatibility, and fork details that make sense for your exact build.

Custom Purpose

Build it for speed, comfort, distance, bikepacking, racing, all-road use, or a balanced gravel setup that does a little of everything.

Geometry

Stock geometry, ready to customize.

Use these numbers as the starting point for your 3 Notch build. The stock geometry below has been updated with a 415mm chainstay length and 395mm fork axle-to-crown.

A good lightweight blanket
Color: Blue Moment, Size: Twin (60 in x 90 in), Color: Blue Moment, Size: Twin (60 in x 90 in)
With perpetually dry hands I have issues with certain fabric textures. This Velvetloft blanket is on the border of triggering, but nothing like how the Classic Extra-Fluffy Plush throw is. The ribbing is interesting visually, but also made the blanket feel a lot lighter too. Definitely one I'll keep on the couch for a chilly day and not for my bed. When I washed it I was expecting a lot of shedding like the Classic one, but there wasn't as much. I washed it on cold and dried it on the delicate setting since I don't have a good place to air dry. It doesn't appear any worse off than before I washed it. Overall I like this one way more than the Classic, but the Primalush wearable blanket is still my favorite.

Wait until you unroll this beautifully soft blanket! It’s the one you want.
Color: Goose Egg, Size: Twin (60 in x 90 in), Color: Goose Egg, Size: Twin (60 in x 90 in)
I can’t pass up a good blanket, and boy is this one impressive! It’s another high-quality product from Berkshire Home Company. What I love about my goose-egg colored, velvety soft, blanket is the ribbed design. The lines separate the elevated design, and I could literally rub my hand over it throughout an entire movie! It’s SO plush and soft. It’s made from their signature VelvetLoft fabric. Plus the design makes it look like a planned piece of your decor. I like the color I chose but there are others to choose from as well. It’s nice and thick but not too warm. I got the 60”x90” twin size which is great for me! Next time I will get a queen size to go over my bed. The price point is so low for the quality you get! You should stop your search now because this is the best one!

Luxurious VelvetLoft From Berkshire
Color: Stormy Weather, Size: Full/Queen (90 in x 90 in)
Berkshire hits it out of the park with yet another fabulously lux blanket. Their VelvetLoft is my favorite for warmth and softness all while looking like an offering at a high end hotel or B&B. The medium weight was the perfect choice to pair with the large ribbing and while this IS the blanket to choose once the leaves start to fall, it's almost sinful to snuggle up with to watch a movie with the AC humming in the warmer months since it washes like a dream and did not shed at all. I used cold, delicate and my favorite scented delicate wash. Dryer on Medium for 10 minutes and then Low for anther 20 minutes. Perfect! The Stormy Weather is a silvery gray neutral and will work with multiple coverlets, bedspreads and quilts. Perfect gift! Definitelythe blanket you want in the guest room!.

Beautiful blanket
Color: Goose Egg, Size: King (90 in x 108 in), Color: Goose Egg, Size: King (90 in x 108 in)
Really loving this blanket. It’s just beautiful - a step above the average chenille seemingly sold at every drug store/grocery store/shop. Has a lovely sectioned pattern and is generously sized for a king blanket. Plenty of room on both sides of our deep king mattress. Washes up very nicely.. still like new! Note of caution: The label says air or line dry, no heat. Usually I wouldn’t consider any vexing that can’t be regularly washed and dried. But since every chenille shrinks some.. I was careful to machine wash cold abs air dry in drier only and it didn’t shrink at all (go figure). Came out of drier nice and soft still. Great value for this price. Would also make an excellent gift for housewarming/wedding etc.

Lightweight yet warm
Color: Blue Moment, Size: King (90 in x 108 in), Color: Blue Moment, Size: King (90 in x 108 in)
I got this blanket for my hubby and I to use at his parents house -- I got the king to use on a queen bed. It is very soft and fuzzy -- the cats really like it. It is very lightweight but keeps us warm on slightly chilly spring mornings. It machine washed and dried well with almost no lint. It looks good too. This review is for Berkshire Ribbed VelvetLoft® Blanket – 330gsm Medium Weight Plush, Extra Soft & Warm Plush Blanket for Bedroom, Couch, Travel – Durable & Easy Care(Blue Moment, King Size 90" x 108")
