15/44 Sprockets: Fantastic!
Well, I've changed to 15/44 gearing and am really pleased with the result. I've been running with 14/42 for ten years and was never happy with the way the chain ran against the chain guide on the swinging arm, so when the time came for new chain and sprockets I took the opportunity to improve things.
14/42 is equal to 15/45 = 3.00, but apart from 45t sprockets being unavailable, I thought that I'd get away with upping the gearing one tooth and 15/44 is equal to 14/41 = 2.93. When running the 14/42 the transmission was very noisy and snatchy, and I could feel the vibration from the chain running against the swinging arm. With the new set up the it is much quieter and smooth and the gearchange is improved too.
I was amazed at the condition of the 14t Renthal front sprocket that I took off, it appeared to have hardly been run after 10,000 miles and the new 15t Renthal is a beautiful thing, superbly made and finished. The rear sprocket that I fitted is made by Talon and is not as well finished as a Renthal, and is not hard anodised either, but Renthal do not make a 44t for our bikes, so I will have to see how it lasts.
