Currently I have praxis which is 48/32: https://praxiscycles.com/product/alba-m30/

I am looking to change to Shimano (or similar)

I have 2 speed shifter, so triple crank is not an option I want to go.

Usually there are 50/34 or 46/36 combinations.

I was wondering can I put smaller inner chainring on such cranksets? (can I have less than 34 tooth?)

I like to ride the steepest of gradients so every tooth counts

This is the bike I have: https://www.specialized.com/us/en/me...mp-e5/p/128909

Put a 11-36 cassette and a new chain on the bike and be done with it.
That's a good crankset... why you want to change it?

As above, switching out the cassette would be a more cost-effective solution. With a 11-36, the 28/36 combo would give you ~25 gear inches which is a decent, fully loaded touring gear inch.

If your RD cannot handle that range, Wolf Tooth makes an adaptor that can help extend your RD's range.

Didn't we deal with a Praxis to Shimano thread already? same guy?

This is another question if I may.

I dont want praxis because aside from stupid praxis bottom bracket which is more expensive (40eur) than shimano (10 eur) and not any better (the same quality), its not available in EU for me to order (bike24, bike-components all out of stock for a while now, evanscycles not delivering...).

If it were available I would probably already ordered one to see how long its going to last (current one is that came with the bike, lasted about a year).

Better crank than Shimano. Probably a better BB as well.
What are your riding conditions and how do you clean the bike?

utoner34

My riding conditions are normal, mostly dry, but I am on heavy side and like riding steep uphills which obviously crush bb easily.

I can switch to Shimano and sell praxis crank (still in very good condition), then I will have easily available shimano bb when I need it.

To bad I cant put this on my bike:

Hey Utoner, there are a growing number of cranks that come in 46/30 that will shift well with your current road FD and still result in a fairly reasonable descending gear. The obvious answer is the FSA adventure modular cranks. The most affordable 11 speed version is the Omega adventure modular 386evo, followed by the Energy, up to some fancy carbon models. 386 evo bbs are not nearly so common as, say Shimano hollowtech ii, but have somewhat better international distribution than Praxis. Also the Sugino OX601-D is available as a 46/30 and uses Shimano Hollowtech II bbs.

34t is the smallest ring that ordinarily fits a compact crank with a 110mm BCD. Your praxis uses a couple tricks to cram a 32t on there. On a Shimano compact crank the only smaller option is that AbsoluteBlack makes an ovalized 46/30 set for asymmetric 4 bolt Shimano cranks like most of the current 11 speed ones. Looks--distinctive.

As a note--if you can't get a Praxis BB, you can try having a shop remove the bearings from your Praxis BB with a blind bearing puller and replacing them with standard cartridge bearings.

Would this fit?

Whole chainset and BB instead of a chainring? give it a try..

I offer no guarantees.. Buy all the installation tools while you are at it..

If you're willing to scarifice some top end, get an mtb crankset.

cpach

Sure. You'll also need a English threaded 386evo bb (and installation tool—it's unique) .

I asked my lbs, but they are hopeless.
