FrostBike 2013: Problem Solvers Gets SRAM and Shimano to Play Nicely, with new MisMatch Adapters

FrostBike 2013: Problem Solvers Gets SRAM and Shimano to Play Nicely, with new MisMatch Adapters

After SRAM introduced their Matchmaker clamps awhile ago, Shimano finally got on board with a similar brake-shift lever clamp integration set up with their I-Spec compatible shifters. The catch? If you wanted to minimize handlebar clutter, there weren’t a whole lot of options to mix and match. Fortunately, PS is adding another option to the mix.

Qualifying as one of those ideas that makes you think why didn’t I think of that?, the MisMatch adapters are incredibly simple, yet will allow for a cleaner bar setup if you choose to mix and match. Currently, PS only offers a MisMatch adapter for Shimano brake levers with Sram shifters – but you have to ask how long it will be until they offer an adapter for the opposite. The adapters are CNC’d aluminum and are designed for use with Shimano I-Spec compatible brake levers and any SRAM MatchMaker compatible shifter.

Full list of brake lever compatibility after the break along with very cool steel/alloy single speed cog.

It’s little thing like this cassette cog carrier and the MisMatch adapters that make Problem Solvers tick. With single speed cogs you’re usually forced into choosing between inexpensive steel cogs that last a long time, but have such a thin profile that they can dig into softer aluminum freehub bodies. Sure there are some nicer steel cogs out there that have a wider base to distribute the load, but they’re usually pretty expensive. PS’s new cassette cog carrier combines an alloy carrier with a steel cog for the best of both worlds.

The wide alloy base keeps it from chewing up your hub, and the steel cog is super durable, and can be switched out with other inexpensive cogs for different gear ratios without having to buy an entire new unit. As an added bonus, you can remove the alloy carrier and mount the cog to a 6 bolt disc hub. Nice.

Are those mismatch adaptors available now? I need them right now actually and am glad to hear about them!

James - 02/25/13 - 2:22pm

Looks like a home brewed components cog…

It’s not a matter of ‘why didn’t I think of that?’, it’s a matter of somebody actually doing it.

Zach Overholt - 02/25/13 - 3:02pm

@James, it does look like it a little, but there are quite a few differences between the two.

Pedals - 02/25/13 - 3:14pm

Why on Earth would you want to run Avid brakes with Shimano shifters?

Josh - 02/25/13 - 3:19pm

Hey Zach,

Here’s a video about the mismatch adapters if you’re interested including this:

That guy is done, no longer making parts and has $3000.00 worth of peoples money tied up and will not provide any refunds for undelivered product.

Brian - 02/25/13 - 3:27pm

Hope has been making a matchmaker style bit for a while now. Running my hope brakes connected to my SRAM shifters works really well. I’d imagine that the hope bits could be used to make other matches too.

Kailua - 02/25/13 - 3:42pm

@James – They look similar except it won’t take six months to a year to maybe get your parts.

Jake - 02/25/13 - 3:43pm

SHUT UP AND TAKE MY MONEY!!! (for the mismatch adaptors)… XT brakes and XX shifters don’t play well together…

Nic - 02/25/13 - 4:05pm

Other way has been done by the Germans

Nic - 02/25/13 - 4:08pm

P.S. running hope adaptors on Juicy 7 and Formula R1 with Shimano shifters.

Zach D - 02/25/13 - 4:23pm

Origin-8 has been making those SS cogs for a little while.

Taylor - 02/25/13 - 4:28pm

Is there an adapter for XTR shifters and Magura MT-6 brakes???

Joshua Murdock - 02/25/13 - 6:10pm

I think a better solution would be to simply run Shimano brakes and have a bike that actually stops… Still, though, these are very cool. Great idea.

nh - 02/25/13 - 6:26pm

That is great so many people prefer sram for shifting and shimano for stopping.

Also the single speed cog mounted to the brake mounts. This weekend I will be getting the drill out to make me old mtb wheel into a fixie.

limba - 03/03/13 - 4:25pm

What does it weigh?

sweed - 03/19/13 - 11:22pm

I just tired them and they are not adjustable. You can’t even reach the bottom leaver. Great idea poor exaction. Need to move up and rotate.

Swami - 05/13/13 - 11:44am

Just installed MisMatch adapters, I’m with sweed on this, poor execution, a discombobulation of a setup that forces the shifter too far back. My setup is XTR brake/XX shifter. Much more adjustable with the stock XX clamps.
