Gravel wheels: Light vs Aero?

reviving older thread…

how do you order wheels online? I have a 2019 Giant Advanced Revolt 1.

I’m not sure how to go about getting the right wheel if I wanted to get a 2nd wheelset.

I have 6 bolts holding the disc brakes on. I can measure the diameter of the thru axles.

I have stock SRAM cassette on it. The largest cog says ‘XD compatible only’

Couple specific questions.

  1. Is the width of the hub standard for 700cc wheels? or is this something I will have to measure?
  2. Is the mounting of the disc standard interms of ‘offset’ for a lack of better term? I have visions of my calipers not aligning properly to the disc if I buy new wheels.
  3. Do I have to get a wheelset for a SRAM cassette? or can I switch the cassette to Shimano on the 2nd rear wheel…

I’m a newb.

Hey @Petee looking at your frame on here it looks very standard: 2019 Giant Revolt Advanced 1 – Specs, Comparisons, Reviews – 99 Spokes

so 12 mm thru axles on both ends and 142mm rear. This is what most disc wheelsets are so will give you lot of options.

The first question is why are you wanting a second wheelset? Stock wheels tend to be very sturdy and reliable if heavy. Great for rougher use or if you are a heavy rider. If you just want a second wheelset of similar type to maybe run road tires on then you can likely pickup a very similar type of wheels locally on Kijiji or similar for very little money. The reason to go online would be to save money on a fancier / lighter set (like the 9velo I got above).

So you answer your three questions:

  1. your bike is running standard gravel / wheels. If you have something you like the look of, post it and we can advise you if it will work.
  2. In theory you should be able to swap wheels back and forth with no issues but disc rotor clearances are so tight that it doesn’t need much for the rotors to rub on a wheel swap. You might be lucky but I often have to adjust the brake calipers when I swap wheelsets.
  3. Yes you can run a Shimano cassette but with a few caveats. Some people swear the shifting is better when you keep everything one brand. I don’t really notice the difference but you might. Also the cassettes ranges from SRAM to Shimano maybe different so you might not get exactly the same range with a Shimano cassette (different gear sprokets in between for example). Some wheel hubs you can swap the body so to go from a SRAM to a Shimano and the body is quite cheap normally, just a matter of finding it which can be tricky.

Thx @Oliver_Smith,

2nd set of wheels for road tires would be the goal. I would put the chunkier tires on for rides with the family as they are slower, but the road oriented tires would be nice for the rec road rides with WCC.

How much of a chore is it to adjust the brake calipers? Is it fairly quick?

I have 2 sets of rubber right now, but one wheelset.

You really should be able to set wheels up so you dont need to adjust the calipers. Assuming the rotors are the same thickness and true then you should be good to go. There can be manufactuing tollerance issues for spacing, but you can get shims to move the rotors.

I have 3 sets of wheels for my cx bike and never have to adjust the calipers assuming thr rotors are true. If you do have to adjust them you should be able to adjust them in a minute, it is a case of loosening two caliper bolts and re tightening.

If the stock wheels are as described in one review you will appreciate about any other wheelset. Giant’s lower end stock wheels are heavy, I had an older set that were terrible at staying true.

I’d recommend using the same type of freehub on both wheels. You can mix and match cassettes, but life is easier with one standard.

Found this on adjusting calipers…
