The Thunder One 29r frame uses Breezer D'Fusion tubing, their Apex Disc Mount and Breeze-In dropouts. Its 29er geometry is identical to the Cloud 9 but in durable, lightweight aluminum. The Thunder uses a custom Breeze tapered head tube for additional stiffness and weight savings, and is the first ever Breezer single-speed. With its derailleur hanger and eccentric bottom bracket it easily accommodates both geared and singlespeed setup. If you have ever tried to set up a singlespeed with disc brakes and horizontal dropouts you'll appreciate how much easier the eccentric bottom bracket is to deal with. It makes fixing a flat or changing tires... a Breeze.
Q: Do you have geometry for this frame? I'm looking for an XL. Also I plan on using this as a singlespeed. I already have a good rigid fork. Do you sell and adapter to use a non-tapered fork with a tapered head tube that this frame has? Thanks. Mike
A: The geometry for the 2014 Thunder One is the same as the 2013 model, which can be found here:
We also have the proper lower headset you will need to use in order to accommodate a non-tapered fork. As this frame uses an integrated-style headset, you need to choose an “IS52” lower that works with a 1 1/8” steer tube (i.e. item 205 CACIB1).
Q: What is the Apex Disc Brake Mount (51mm IS)? Will my standard (common) disc brakes fit? Also, what is the mount style and size for the front derailleur? Do you have the weights for the XL and L frames? Thank you!
A: Most bike frames use an IS 51mm rear brake mount. There is a good chance your current frame has an IS rear brake. The Thunder One is designed around being a single speed or 1x bike so it is not designed around a front derailleur. The seat tube sizing is 34.9 so a 34.9 clamp will fit. We do not have a listed weight for the XL or L.
