The Wavelength&#8217;s double-butted, 1.45&#8243; diameter down-tube features Sunday&#8217;s proven Wave shaping to help fight against denting from rails, ledges, coping and whatever else happens to get thrown at it.<\/li>\n<li>Miter Cut Top Tube:<br \/>\nA miter-cut top tube creates a precise joint with the seat stays during welding. This increases the strength substantially over frames that use a \u201csandwiched\u201d top tube at this critical junction.<\/li>\n<li>Tapered Chain &amp; Seat Stays:<br \/>\nBoth chain and seat stays taper to provide a refined and clean look to the frame while still providing strength. They are both angled on the inside for improved chain clearance and weight savings.<\/li>\n<li>Hollow Dropouts with Chain Tensioners:<br \/>\nHollow 8mm wide dropouts are as light as a solid 5mm dropout, but over twice as strong. There is a small internal chain tensioner to hold the wheel in position and to simplify wheel removal.<\/li>\n<\/ul>\n<h3>Geometry<\/h3>\n<p><strong>Top Tube:<\/strong>\u00a020.5&#8243;, 20.75&#8243;, 21&#8243;, or 21.25\u201d<br \/>\n<strong>Head Tube Angle:<\/strong>\u00a075\u00b0<br \/>\n<strong>Seat Tube Angle:<\/strong>\u00a071\u00b0<br \/>\n<strong>Chainstay Length:<\/strong>\u00a013.45-13.70\u201d<br \/>\n<strong>Bottom Bracket Height:\u00a0<\/strong>11.625\u201d<br \/>\n<strong>Standover:<\/strong>\u00a09.5\u201d<br \/>\n<strong>Tire Clearance:<\/strong>\u00a02.40\u201d<br \/>\n<strong>Head Tube Length:<\/strong>\u00a05\u201d<\/p>\n<p><iframe loading=\"lazy\" title=\"BRETT SILVA | Sunday Bikes - SILVAWAVE Frame\" width=\"1170\" height=\"658\" src=\"https:\/\/www.youtube.com\/embed\/eoKSy7eGHIQ?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Made entirely from 4130 chromoly, features Sunday\u2019s signature dent-resistant wave downtube, which gives riders more confidence during challenging sessions.<\/p>\n","protected":false},"featured_media":8836,"comment_status":"open","ping_status":"closed","template":"","meta":[],"etheme_brands":[{"term_id":456,"name":"Sunday Bikes","slug":"sunday-bikes","term_group":0,"term_taxonomy_id":456,"taxonomy":"brand","description":"Sunday is a prominent brand specializing in the production of BMX bikes and accessories.
