2 x 10 Chainring replacement

[mataz]

I am currently running a 40-28 Shimano XT Crankset but my small ring is worn and I want to replace it.

 

I am battling to find a 28 tooth but I am able to get a 26 tooth, will this work or will it cause hassles with the shifting? Also, is the BCD of the smaller ring the same?

 

Would appreciate some advice.

28 and 26 and 24 and 22 for that matter all have a 64 BCD, should be ok with a 26, if I recall the shift ramps are on the outer ring and not the small and a 14t tooth difference is probably the max you would want. Usually its 12......
