in MTB buying advice
Hi I am looking to replace my crankset on my Boardman MTB TEAM Hardtail 29er 2014 with original FSA Comet 368 39/27t I was considering purchasing this item https://www.jejamescycles.com/product/44077/shimano-deore-shimano-fc-m4100-deore-10-speed-36-26t-chainset/option/ if it is compatible with current setup?
I look forward to any suggestions and advice.

    This was answered the other day when you asked in MTB Workshop and Tech.
    It will be fine as long as you have a compatible bb.

    So on a difficulty level how hard is it to change and any pitfalls I should be aware of before tackling the job it also states chain line is 48.8mm compared to the comet which apparently 50.0mm would this effort or cause any problems

    I missed the other discussion. 48.8 and 50mm chainline difference is miniscule and won't matter in the slightest.

    Difficulty regarding what aspect, fitting a new bb, crankset or something else? 🤔

    I have fitted bb52 on my own bike so how removed my own crankset deore FC-M610 without any problems just wondering if I will run into any problems? Surly can’t be that simple?

    It is that simple, that's another reason why Hollowtech II bb's and cranks are good.

    Pre tensioning the nds crank arm for correct fit without play or knocking but not too tight the bearings bind is about as hard as the fitting process gets which sometimes gets overlooked and not done properly.

    Yep, it's a double, HT2 and there's a 48.8mm chainline version option:-

    I'd recomend you adjust the height and then re-tune your front derailleur to account for the slightly smaller big chainring difference and you'll end up with slightly lower overall gearing.
