Cogs from Two Cassettes?
I posted this over in the mechanics area and got one reply which was helpful. I would like opinions/advice from my brothers and sisters here at 50+
My road bike has an 8-speed Sora triple drive train. I had the original equipment 12-24 cassette changed to a SRAM 11-28 for a century with a good bit of climbing, allegedly 6,300'+. The original cassette is in good shape. The original equipment cogs are: 12, 13, 14, 15, 16, 18, 21, 24. The new cogs are: 11, 12, 14, 16, 18, 21, 24, 28.
I've been training with the new cassette, and it appears that, for me, the 11-tooth cog is a bit too much. One the other end, the 28-tooth cog is great for hills > or = 10%
Is there any mechanical reason that I could not have the 11-tooth cog removed from the new cassette and replace it, in the proper size order of course, with either the 13-tooth or the 15-tooth cog from the old cassette?
Thanks for any assistance.
