The -17 degree angle suits riders who want a more aggressive, lower front end on their XC or trail setup.\u003c\/p\u003e\n\n\u003cp\u003eWhat separates the Tharsis from a standard stem is its \u003cstrong\u003eintegrated external headset adjuster\u003c\/strong\u003e — a dial built into the underside of the stem that replaces the need for a star-fangled nut or expander plug inside your steerer tube. You clamp the stem, use the dial to remove headset play, and you're done. That open steerer also creates a useful cavity: on steerer tubes 152mm or deeper, a Shimano Di2 battery can be routed and housed internally, keeping your cockpit clean and the battery accessible without disturbing your saddle height. Available in 70mm, 80mm, and 90mm lengths to suit a range of rider positions.\u003c\/p\u003e\n\n\u003ch3\u003ePRO Tharsis XC Stem -17 Degree Specs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n  \u003cli\u003eMaterial: 7075 aluminum with titanium bolts\u003c\/li\u003e\n  \u003cli\u003eRise: -17 degrees\u003c\/li\u003e\n  \u003cli\u003eLengths available: 70mm, 80mm, 90mm\u003c\/li\u003e\n  \u003cli\u003eIntegrated external headset adjuster — no star-fangled nut required\u003c\/li\u003e\n  \u003cli\u003eCompatible with internal Di2 battery routing on steerers 152mm and deeper\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"PRO","offers":[{"title":"Black \/ 70mm","offer_id":43516861317164,"sku":"PRSS0313","price":69.99,"currency_code":"USD","in_stock":false},{"title":"Black \/ 80mm","offer_id":43516861349932,"sku":"PRSS0314","price":69.99,"currency_code":"USD","in_stock":true},{"title":"Black \/ 90mm","offer_id":43516861382700,"sku":"PRSS0315","price":69.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/pro-tharsis-xc-stem-17-degree-4018819.jpg?v=1771299069","url":"https:\/\/ricycles.com\/products\/pro-tharsis-xc-17-stem","provider":"RA Cycles","version":"1.0","type":"link"}
