Upgrading Chainring

987 Views 4 Replies 4 Participants Last post by  Tippster
I have an Shimano AceraX, 22/32/42 teeth on my Trek right now. I want to upgrade the large chainring to a 44. Can I get any shimano 44 ring as long as its a 4 bolt pattern and be compatible? Also does anyone know if the large and medium are welded together. I do believe the small and medium are. Any help on this would be great.

The bike is at my house so I cannot look at it for a couple of days since I'm out of town and I want to order the parts. Many thanks,

Well cost wise it would be better to get a whole new crankset

I'm not familar with the current AceraX setup so I cant comment on the ability to replace a ring but it would cost about the same to buy a new crankset. A new Shimano outer ring will run you at least $50.
do you relise that changing from 42 to 44 up front will have very little impact on your gear ratios.


What is it you are trying to achieve?

What is your budget?

What type of riding do you intend to do?
Can I piggyback with a newbie question? I bought a bike and started riding religously over the past few months. I ride semi-technical xc trails, want to try more technicals soon. I do like to ride fairly aggressive; attacking for speed in spots as they come. Might even want to try a race. But I have no clue what different ring sizes are suited for. I'm cranking a 48-38-28 now. Whats the deal with rings?
44/32/22 is the standard mtb set-up as your chainrings.

11-32 or 11-34 is the standard mtb set-up for your cassette.


The most likely reason to put a 48T chainring on a mtb would be to use it on the road.

with 48T front and 11T rear, you have a very similar gear ratio as

52T front and 12T rear (as you would find on a road bike)


The problem with large chainrings is that you rob yourself of clearance off-road. You also add additional weight to your bike.
