Hi Bro and Sis, I would like to introduce the latest design of I-carus cadence magnet as in pic 1. Guarantee Satisfaction!! Best Quality and Best Price Only RM35/pc including shipment (Malaysia Only). Suitable for all kinds of bike with cadence sensor (MTB, Road, Touring, etc.) What a waste with full of tape and rubber band just to hold a magnet onto your crank arm:- 1) Silky crankset carbon design been cover up as shown in pic 2. 2) Dust entrapped between crank and tape/rubber band. 3) Difficult to clean your crankset. 4) Expensive crankset brand that wanna show off been cover up. 5) Easily to peel off or missing magnet + additional weight. Now I can help you to solve your problem:- 1) No tape or glue required. 2) Simple and easy. Just place it on to your paddle axel as in pic 3. 3) Easy to clean and crankset looks great. 4) Dont have to feel worry that magnet will get missing during riding. 5) Slim design, totally smooth against your crankset arm as in pic 4. 6) Reduce weight because rubber band been removed as in pic 5. Note: Currently, not compatible with Titanium axle pedals. Interested, give me a call at 012-4110537 (Calvin Lee from Butterworth/Penang). Thanks BBS member for viewing!!! Mesti Puas Hati Punya!!!
