Whippet
A fast and comfortable gravel bike that's easy to love
This page is a work in progress. I'm currently (Oct. 9, 2024) waiting for some machined parts so I can build a second prototype for testing.
Feel free to poke around. You'll find a geometry chart below. This isn't set in stone yet. But it'll likely be really close to the final numbers.
Soon you'll also be able to easily figure out what size frame will fit you. I'm really excited about this. It's a calculator that you'll adjust in order to know not only the right frame size but also the right stem length, stem angle, and spacer stack you'll need to set up your bike for an accurate fit.

FAQ
Can I run a front derailleur?
No. The bike frame is optimized for 1x drivetrains.
Can I run 650b wheels?
The two smallest sizes are designed around 650b wheels. All other sizes are designed around 700c wheels. If you run 650b wheels on the larger frame sizes your bottom bracket will drop around 19mm. That may cause frequent pedal strikes riding off road. Therefore, it's not recommended.
What's the max weight I can carry on a rear rack?
The frame isn't designed for carrying heavy rear loads. I'd recommend carrying no more than 8lbs, including the weight of the rack.
What's the max weight I can carry on the fork?
The Seido MGV fork can carry a max load of 6.6lbs using a 2-bolt cage, 9.9lbs using a 3-bolt cage, 44lbs for a lowrider rack with 4 mounting points, and 22lbs for a rack with 3 mounting points.
Can I get the frame and/or fork custom painted?
Yes you can. Contact me for pricing and turnaround time.
How many headset spacers can I use?
Seido limits the total headset stack under the stem to 20mm. You also need to use a 5mm spacer above the stem.
Can I run a suspension fork on this frame?
Most gravel suspension forks with 30mm-50mm of travel will work. The taller fork length will likely slacken the seat tube and head tube angles a bit, but not enough to dramatically change how the bike handles.
I don't want to run a carbon fork. Can you make me a steel fork instead?
Yes. For an additional $400, I can make you a steel fork that will be powdercoated the same color as your frame.
Can I run my housing internally?
The Whippet is designed to be easy to maintain. All lines run externally along the down tube with a port in the seat tube for running an optional dropper post. If you want a bike with full internal lines, I'm happy to make you a custom bike instead.
