Mixing Miche cogs with Shimano

davidseume

Hi. I am currently using a Shimano 105 5800 11-speed cassette (11-12-13-14-16-18-20-22-25-28-32) on my Look 765.
I do a modest mileage and the bike is well maintained, so wear is likely to be minimal. I can’t say the same for my legs; I’ve been using the same pair for the past 70 years and they’re not as strong as they once were! The reality is that I don’t use the 11 and 12 cogs at all and would prefer to lose those, along with some of the gaps, and have something like this: 13-14-15-16-17-18-20-22-25-28-32.
Obviously, I would need to source new 13, 14, 15 and 17 sprockets to replace the top pair and fill the gaps.
Does anyone have any experience of doing this, or something similar, or any thoughts on my idea?

Miche cogs cannot be mixed with Shimano sprockets. The shifting will be off. Sprocket thickness are different as are the spacer thickness. They give 11 speed Shimano spacing only if miche cogs and spacers are used together.

If someone tells me that what they are intending to mix and match I refuse to make the sale. I used to get angry emails from customers telling me how crap miche sprockets are but after asking them if find our they are mixing and matching... And I had to explain the error in the assumption they made.

13-32t are possible with a miche cassette but you need a retailer that buys individual miche sprockets from miche. The u.k distributor does not bring in 13t start cassettes. I know one retailer that does though.

Thank you. Useful information.
“I know one retailer that does though.”
Who would that be?

You could mix the individual Shimano sprockets and sprocket clusters from a 14-28 with your existing 11-32; a new 11-30; a new 11-32; or a new 11-34.

Shimano 11-speed 14-28 cassettes aren't cheap, a brief scour of the internet looks like £50 (before ~£5 p&p) might be the cheapest in the UK https://www.evanscycles.com/shimano-ult ... e-EV310895 , or ~£41 from https://www.bike-discount.de/en/buy/shi ... -28-625113

https://www.merlincycles.com/shimano-10 ... 17086.html looks to be a decent price for more conventional ranges at the mo, ~£35-37.

You can get individual Miche sprockets/spacers/lockring from Italy through the ebay shop linked below. Not sure how cost effective it would be to put together an entire cassette this way though. Maybe buying a complete Miche cassette with a couple of additional sprockets to achieve you desired ratios would be more doable?

I hint drop at who that retailer is. Connect the dots. or do a web serach for Miche cassette...

Does eveything have to be spoon fed?

Ridewill cant have the Miche 12 speed cassette. Miche are shipping one to me next week. This is there first production run.

I ordered last august with factory.

Mixing and matching shimano cassette will probably mean poor shifting. Shimano cassette are designed to work together. A cluster from one does not always match a cluster from another not to mention the jumps between the sprockets could cause an issue.

The miche cassette is the only solution for a 13-32T

I only have experience with adding some Miche 10sp cogs to a Shimano 10sp cassette. The Miche cogs, as already mentioned, are a different thickness as well as having an offset. Having spent a silly amount of time trying to sand down spacers to position the cogs the correct distance apart and then still having crap shifting it definitely wasn't worth the effort. Go to the shimano site and they will list the exact individual cog part # for whatever model cassette you have and do a search or go to your LBS and they may be able to order one for you. By the way 11sp cogs will work with a 10sp cassette but you just need to use the correct spacers.

I’ve been using a Miche 13-34 cassette I obtained from Malcolm at the cycleclinic for several months now with a shimano 5800 groupset, it shifts just as well as my old shimano 11-28 cassette.
