Our buddies at Paul Component Engineering based the original Groovy Barrel Adjusters from Magura’s 1970s adjusters, but scaled them down by 50%. The original Magura adjusters were massive, so you could adjust your moto cables through thick gloves. Now, they’ve gone even smaller with these cute Baby Groovy Barrel Adjusters ($20 – $60). You can use these on everything from brake levers, calipers, derailleurs, or hangers.

Paul precision-machines these in HOT ass (it’s supposed to hit 110º today) Chico California from 6061 American milled aluminum or natural brass, anodize them every color of the rainbow, and they’re available in Paul’s Webshop or from your favorite bike shop… right now.
