CrankBrothers iodine 3 stem and iodine 11 bars Review

Components Pro Reviews



iodine 11 bars
The iodine 11 handlebars are made with high modulus uni-directional carbon fiber, have a 30mm rise, 31.8mm clamping diameter and 5° upward sweep. It comes in several width options, a 680mm with a 6° back sweep, and 700mm, 740mm and 780mm with 9° back sweep. They come in carbon black, weigh in at 178 grams (700mm), and retail for $120. The stem clamp section has a functional grip tape strip for anti-slippage, and markings for cuttings and component angling.

The top of the line iodine 11 carbon bars are quite nice looking, as they are subtle, with quiet and subdued graphics. Installation was nice with the anti-slippage grip tape, and once the bars were clamped down; they never moved, though the tape was too thick on initial insertion into the stem. After sliding the brake and shifters onto the bars, there was a useful set of tick marks to get those components evenly angled. Depending on the bar width, there are cutting marks every 20mm at the bar ends to shorten them down to 680mm. The 740mm test bars had a nice resiliency, and did a good job of damping vibrations, especially during forays into rock gardens and when going downhill. I found that they had a bit too much flex/give for my taste during uphill maneuvering, during climbs, technical trial type movements, and anytime you were moving slower and were torquing the bars hard. Although it was subtle, it made for a loss of control, and precision steering, and I felt as though I lost laser-like accuracy. I think they would be a better candidate for a bike with 3-4 inches of suspension, and not the typical All Mountain beasts? They are a good set of bars, with great damping properties, an excellent price, but have a slight flex or give when pushed hard, although the 740mm test width might have exacerbated the issue?
