Product details
The Prickly 31.8mm Direct Mount Stem is listed with 25mm rise, 7075 construction and a stated weight of 107g. Choose Raw or Black, and match the 31.8mm clamp to your handlebars.
Reach needs confirmation
The manufacturer’s description gives both 40mm and 50mm reach measurements. Confirm the supplied version’s reach with Riot Racing before choosing it for a specific bar position.
Listed package contents
- One 31.8mm direct mount stem, including the bottom and two top clamps
- Four M5 clamp bolts
- Four M6 mounting bolts
The supplier’s hardware descriptions also differ on material and grade. Confirm the supplied bolt specification if replacing hardware, and use the manufacturer’s installation instructions. Handlebars are sold separately.
Check the fork and headset setup
The manufacturer notes fork-tube trimming and headset spacers when replacing a stock stem. Review that requirement with a qualified installer for your actual fork, crown and headset before purchase.
Compare the 31.8mm option on our Prickly handlebar page or contact Riot Racing with your bike and fork details for fitment help.
