Upgrade components for Topstone 105?

Trying to decide b/w upgrading the crankset to Shimano GRX 810 (48x31) or wheelset to Mavic Allroad. Not sure how much of an upgrade the wheelset is but would change out tires to Gravelking SK's. also if i change the crankset does that require the GRX FD? Thoughts?

What are you trying to gain with a crank swap ?. Gearing is nearly the same. A different crank might save a tad bit of weight, but ainít cheap.

I could see extra wheels, I did this right away so as to run 28mm road tires with a road oriented cassette. Makes the bike into a decent road bike with a quick wheel swap,

I have a Topstone alloy 105 also and I have considered the same changes. I agree with SteveB. that the crank is a a very marginal gain unless you make a drastic change to the gear range. Wheels are something I am looking into for my bike as I would like to have the added benefit of a different set of tires that can be easily swapped out. I do not have any hands on with the GRX though it does look interesting. I will be interested in seeing what you ultimately do and how it changes the bike for you. Personally I am so happy with what the bike is as stock I am reluctant to make any big changes other than the stem and seat.

I am happy with the bike but have some credit to use so I was thinking one of these two. Wheelset would probably be more useful to make it dual purpose or have a wheelset with a Gravelking SK or something more non mud friendly.

You would a new FD if you went with the GRX crank, due to the increase in chainline. The GRX stuff is very nice, but unless you need the lower gearing, it wouldn't be the wisest place to put your money.

Wheels are always the best bank for you buck, and having two sets for a gravel bike is handy, but the Mavic Allroads and extremely heavy, with less-than-stellar hubs. I'd look at something else.

WHEELS. The Topstone wheels are astonishingly heavy.

I would change the wheels first. I have a topstone and will be doing that. The stock wheels are very heavy.

I will probably change the crank at some point this year. It will save a little weight and I donít like the look of the FSA crank, but it wonít add all that much performance (not like the wheels). Options include GRX (which will require FD), Easton EA90, and Praxis Zayante Carbon. But wheels first, then crank.

The crank weight savings is 2 oz. FSA Omega ME is 871 grams according to their website. The 2x11 GRX 46/31 is 817 grams.

GRX is a very nice group, has some nice benefits like greater cassette range options, clutched rear derailer, supposed to have a very nice feel to the shifters, but itís also a very expensive group to buy. Iíll wait till they introduce a 105
level.
