If you're serious about triathlons, you've probably found that the 39-tooth inner-chainring that's found on most cranks just isn't cutting it. If that's the case, step up to the plate with the Dimension Inner Chainring. Its aluminum construction is built for putting in the miles, and its taller-than-average gear ratio will decrease your time over the course. So, if you're currently peaking your rig out with a 55-tooth outer-ring, we recommend pairing it with this 42-tooth inner-chainring. After all, triathlon is a game of preparation, and having the right gearing makes all of the difference. However, you needn't worry about mix-and-matching compatibility, as this inner-ring is compatible with any 130 BCD crank.
The Dimension Inner Chainring is available in 42-tooth size and in the color Silver. Please note that this chainring is only compatible with 130 BCD cranks, and that it does not include chainring bolts.
