Ultegra 6800 (11-speed) cassette question:
I want a 12-28 but bike came with 11-28. Any reason I can't combine bottom five cogs of 12-25 with top 6 cogs of 11-28 and vice-versa, keep resulting 12-28 and sell 11-25, and thus avoid having to spend silly money on Dura-Ace.
I've had a bit of a Google fail here and couldn't can't find these details on the official Shimano website, so cogs are unconfirmed but listed as here.
Plan is:
11-28 original:
11-12-13-14-15-17-19-21-23-25-28
12-25 original:
12-13-14-15-16-17-18-19-21-23-25
11-25 new:
11-12-13-14-15-17-18-19-21-23-25
12-28 new:
12-13-14-15-16-17-19-21-23-25-28
If, as on previous generations Shimano stuff, the biggest 3 are a block and the rest are individual with spacers, then this seems feasible to me, but can anyone here confirm/deny?
Even if I couldn't shift a 11-25 without the magical 16T cog, buying 2 new Ultegra cassettes would still work out a lot cheaper than buying a DA one.
TLDR: Wish Shimano made an 11-speed 12-28 that cost < £100
