HistoryThe first Speedplay pedal, the X, was patented in July 1989 by Richard Byrne. The company was founded in July, 1991.[3] The Frog, the lightest recessed-cleat pedal system at the time, was patented in September 1992[4] TechnologySpeedplay road and mountain pedals are characterized by double-sided entry, a rider can step on either side to engage the cleat, and float; the foot is free to rotate from side to side about the center of the pedal.[5] The float is reported to be easy on the knee joints.[6] Metrigear designed a cycling power meter to fit inside the hollow spindles of Speedplay pedals,[7] but the company was acquired by Garmin in 2010 and the technology incorporated into Garmin's Vector pedal system.[8] References1. ^{{cite web| url = http://www.speedplay.com/index.cfm?fuseaction=home.newslatest| title = Speedplay News| publisher = Speedplay Inc.| accessdate = 2010-04-26}} {{American bicycle manufacturers}}2. ^{{cite web| url = http://www.dailypeloton.com/speedplayrev.asp| title = A Speedplay Pedal Review | author = Gary Kristense | publisher = Daily Peloton - Pro Cycling News| accessdate = 2010-04-26}} 3. ^{{cite web| url = http://www.bicycleretailer.com/post-134/speedplay-from-startup-to-small-giant| title = Speedplay: From Startup to Small Giant| author = Lynette Carpiet| date = May 26, 2009| publisher = Bicycle Retailer & Industry News | accessdate = 2010-04-26}} 4. ^{{cite web| url = http://www.speedplay.com/index.cfm?fuseaction=home.history| title = Bicycle Pedal Timeline| publisher = Speedplay Inc.| accessdate = 2010-04-26}} 5. ^{{cite web| url = http://www.bicycling.com/gear/detail/0,7989,s1-17-146-2666-0,00.html| title = Gear & Bike Reviews: The Speedplay Zero Pedals| publisher = Bicycling Magazine| date = Dec 2009| accessdate = 2010-04-26}} 6. ^{{cite web| url = http://www.bikeradar.com/fitness/article/buyers-guide-to-clipless-road-pedals--15| title = Buyer's Guide to Clipless Road Pedals| author = Jez Loftus| date = 1 Apr 2007| publisher = BikeRadar| accessdate = 2010-04-26}} 7. ^{{cite web| url = http://www.bikeradar.com/news/article/delays-push-metrigear-vector-release-to-mid-2010-24522| title = Delays push MetriGear Vector release to mid-2010| author = James Huang| date = 6 Jan 2010| publisher = BikeRadar| accessdate = 2010-04-26}} 8. ^{{cite web |url= http://velonews.competitor.com/2010/09/interbike/garmin-acquires-metrigear-creator-of-pedal-based-power-measurement-device_142041 |title=Garmin acquires MetriGear, creator of pedal-based power measurement device - VeloNews.com |first= |last=|work=velonews.competitor.com |year=January 28, 2011 |accessdate=May 4, 2015}} 2 : Bicycle parts|Cycle parts manufacturers |
