Machined from 7075 aluminium with titanium bolts, it's a genuinely light stem that doesn't ask you to give anything up structurally to get there.\u003c\/p\u003e\n\n\u003cp\u003eThe standout feature is the integrated external headset adjuster — a dial mounted under the stem body that pre-loads your headset bearings without requiring a star-fangled nut or expander plug inside the steerer tube. That matters beyond just tidiness: with the steerer left unobstructed, you can house a Di2 battery internally if your steerer depth is sufficient, keeping the drivetrain battery out of sight and easy to access without disturbing your saddle position. The +\/-6 degree rise angle suits riders running a relatively neutral, flat bar position — common on modern XC and trail-oriented builds. Available in 90mm and 100mm lengths to dial in your reach.\u003c\/p\u003e\n\n\u003ch3\u003ePRO Tharsis XC (+\/-6) Stem Specs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 7075 aluminium body, titanium bolts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRise:\u003c\/strong\u003e +\/-6 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLengths available:\u003c\/strong\u003e 90mm, 100mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeadset adjuster:\u003c\/strong\u003e Integrated external adjuster — no star nut or expander plug required\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSteerer clamp torque:\u003c\/strong\u003e 5Nm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"PRO","offers":[{"title":"Black \/ 100mm","offer_id":43516860825644,"sku":"PRSS0310","price":69.99,"currency_code":"USD","in_stock":true},{"title":"Black \/ 90mm","offer_id":43516860858412,"sku":"PRSS0309","price":69.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/pro-tharsis-xc-6-stem-9824943.jpg?v=1771299069","url":"https:\/\/ricycles.com\/products\/pro-tharsis-xc-6-stem","provider":"RA Cycles","version":"1.0","type":"link"}
