Claudio Purchased to replace Garmin Vector 3 pedals. Was easy to fit (recommend downloading and following shimano instructions though). Paired with Garmin 820. L/R balance seems a bit off (as reported by numerous reviewers) but otherwise working great. Would definitely recommend unless you want accurate L/R balance data.
Mr CONNELL Great item, works exactly as its supposed to, installation easy, paired with edge 520 straight away, super looking quality chainset, expensive but with the discounts offered by Merlin fantastic buy
