The gain is not a change of mounting system but what you get in return: 45\/50 mm of reach adjustment, a choice of 20 or 30 mm rise, and a far wider, stiffer clamp that keeps the bar put after hard landings. On top of that, you set the bar position to suit you instead of riding what the factory chose.\u003c\/p\u003e\n\u003cp\u003eOn a downhill bike the RSX replaces a conventional steerer-clamp stem — there you also gain a lower front end, because the steerer clamp and the spacers disappear.\u003c\/p\u003e\n\n\u003ch2\u003eKey points\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003ePlug \u0026amp; play fitting\u003c\/strong\u003e — goes onto the stock e-moto crown, no modifications and no extra adapters\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eAdjustable 45 or 50 mm reach\u003c\/strong\u003e — one stem, two settings, no second stem to buy\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eReversible sides\u003c\/strong\u003e — swapping the sides changes the spacing between the bar clamps, wider or narrower\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eFull CNC AL6061\u003c\/strong\u003e — aerospace aluminium, stiffness without the extra weight\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eWide clamping area\u003c\/strong\u003e — the bar holds firmly and will not rotate after an impact\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eBlack finish\u003c\/strong\u003e — also available in \u003ca href=\"\/en-int\/products\/funn-rsx-direct-mount-mostek-szary\"\u003egrey\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eHow rise is measured here\u003c\/h2\u003e\n\u003cp\u003eWorth knowing, because it catches people out: \u003cstrong\u003eon the RSX, rise is measured from the centre of the bar down to the direct mount interface\u003c\/strong\u003e — it is not bar rise. 20 mm gives a lower, more aggressive front end; 30 mm lifts the bar and is more comfortable over long stretches standing up.\u003c\/p\u003e\n\n\u003ch2\u003eWhich version to choose\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eSur-Ron:\u003c\/strong\u003e Funn points to \u003cstrong\u003e31.8 mm with 30 mm rise\u003c\/strong\u003e as the right pick\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003e31.8 mm\u003c\/strong\u003e — fits most e-moto handlebars\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003e35 mm\u003c\/strong\u003e — for thicker DH\/MTB bars, more stiffness where bar meets stem\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eMeasure the diameter at the thickest central section of the bar, where the clamp sits. 31.8 and 35 mm are not interchangeable.\u003c\/p\u003e\n\n\u003ch2\u003eSpecification\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eMaterial:\u003c\/strong\u003e AL6061, full CNC machining\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eMount:\u003c\/strong\u003e direct mount, 30 mm spacing (RockShox Boxxer \/ Fox 40 standard)\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eReach:\u003c\/strong\u003e adjustable 45 \/ 50 mm\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eClamp diameter:\u003c\/strong\u003e 31.8 mm or 35 mm\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eRise:\u003c\/strong\u003e 20 mm or 30 mm\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eWeight 31.8 mm:\u003c\/strong\u003e 140 g (20 mm rise) \/ 160 g (30 mm rise)\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eWeight 35 mm:\u003c\/strong\u003e 137 g (20 mm rise) \/ 154 g (30 mm rise)\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eColour:\u003c\/strong\u003e black\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhat it fits\u003c\/h2\u003e\n\u003cp\u003ePlug \u0026amp; play with stock e-moto forks — their upper crowns carry direct mount holes at 30 mm spacing, the same standard as Boxxer and Fox 40.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSur-Ron Light Bee X and Ultra Bee\u003c\/li\u003e\n\u003cli\u003eTalaria Sting and MX\u003c\/li\u003e\n\u003cli\u003eE-Ride Pro\u003c\/li\u003e\n\u003cli\u003eDownhill and freeride bikes with a dual crown fork\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eWhat decides fitment is the crown, not the badge: if your triple clamp has the direct mount holes, the stem goes on.
