They are fan-friggen-task!! They didn't work well w/ Klockwerks and I gave my shield to BIGLRY. I have Gorilla length arms and w/ the Heli's & Klock combo, the brake lever would hit on very tight walking turns. Switched out to a Windbender. Wickedly comfortable combo (for me). Btw, did a 5 1/2 wk 11K mile trip last year w/ the Heli's. Damn, comfy.
