CrankBrothers Iodine 3 stem

Our review

Light and stiff with some very nice features
Skip to view product specifications

There are a number of features that set this excellent little stem apart from the bunch. The most obvious is the recessed, forward facing steerer clamp. Tightening with one Torx key it has no knee-catching bolts on the rear of the stem and is very tidy indeed. Of course, you’ll need to double check your multitool has a Torx T25 on board.


A carbon fibre faceplate is a nice addition to the performance. There is also the weight – our 80mm model didn’t exactly trouble the scales at 150g, yet its all-mountain credentials shone through with no signs of flex when wrenching the bars around on nadgery trail.
