    Wave C frames now available!

    Yes, the highly anticipated 24" Wave C frame is now available!  We've made some updates to the original Model-C frame that make it even stronger and more agile. The chainstay length was shortened from 15" to 14.6" which will allow the front end to come up easier and make it easier for spinning tricks. All of our aftermarket frame features like Wave toptube and downtube, hollow dropouts with built in chain tensioner, removable brake mounts, cable channel, post-weld machining of the bb and headtube and 41 Thermal heat-treating can all be found on this frame.  Plus we've added more room to the frame by offering it in a larger 22" size, so you'll be able to get it in either 21.25" or 22".  This is one tough frame!  Check after the break for the frame specs and features. Learn more about the Model C geometry HERE.

    Wave Top Tube Xplained

    Last year, we showed you the inside of a Wave down tube.  Now, with the soon to be released Third Wave (just over 3 weeks away), we are showing you the cross-section of the Wave down tube and our new Wave top tube.  These top and down tubes are custom drawn tubing shapes that are formed using the same manufacturing steps as a traditional, seamless, round bicycle tubes. The difference is that we’ve put the shape’s contour design to work for you. The tubes are drawn into shape with strategically formed Waves that run along the entire length of the tube. Now, if you're not familiar with the functional purpose of the Waves, they're designed to make the frame more resistant to the accidental denting damage that can occur when you’re riding.  While no bicycle tube is “dent proof”, these tubes have been engineered to withstand more abuse than a traditional round tube. After all, once a tube has been dented during riding, the strength of the frame’s front end has been compromised.  And it doesn't matter whether the dent is on the top tube or down tube.  Included in the cross-section is the Cable Channel which can be found on the underside of the top tube.  The Cable Channel is used to partially hide the brake cable, and it also allows for the attachment point of the pressure fit cable guide.  For more info about how this cable guide works, follow this link. Choose wisely! For even more info check out our recent “Enter the Wave” ad.

    New Removable Brake Mounts Xplained!

    Here's brief pictorial description of our new removable brake system that is available on the Third Wave, new Funday and Forecaster frames.  It is made up of 3 elements: Gyro tabs with screws, pressure fit cable guide and brake mounts. The gyro tabs are your standard removable gyro tab. The cable guide is really unique because it uses the cable's tension to keep itself attached to the frame.  There's a little tab welded in a channel that runs the length of the underside of the top tube.  The channel not only allows for a place to attach the cable guide, but acts to hide the brake cable too.  At the tab, the cable guide is installed from the front then the brake cable is installed like any normal braking system.  The tension created at the tab is enough to hold the whole system in place.  There's no holes, no screws just a simple system. Starting this year, all Sunday frames will come with removable brake mounts.  Remember all Sunday mounts are angled which is a Sunday original.  It is possible to attach the mounts in 2 ways: A 10mm wrench flat on the outside or a 4mm allen slot on the inside of the mount.  Put them on or take them off, either way the mounts attach super simple and super clean.

    Wave Toptube Update!

    Eric Lichtenberger had a bike check of his Third Wave prototype a few days ago, but we didn't get to show you close ups of the Wave on the toptube.  The photos aren't the best, but you will notice a bunch of scratches and dings, but no major dents.  The idea behind the Wave toptube is the same as the one for the downtube.  Each small Wave is stronger and stiffer than a non-waved tube, it's easier to dent a larger tube then a smaller one.  We've been doing the Wave downtube since 2007 and it's been proven countless times.  If you dent either one then you significantly decrease the strength of the front end.  The Wave toptube will only be offered on next spring's Third Wave frame.  Look for more photos of the Wave downtube including the cable channel on the underside next week!
