I would like to estimate the price of a bike if bought in parts.

  1. One thing is the frame, that is easy.

  2. The front and rear shock can also easily be checked out as individual components.

  3. Tires

  4. A groupset seems to include:

    • brakes
    • shifters
    • drivetrain
    • BB
    • hubs.

Those categories are easy to check for price on the manufacturers sites.

However, a few pieces remain:

  • saddle
  • stem
  • bars
  • grips
  • seatpost
  • spokes
  • rims
  • axles
  • pedals.

IMHO those peaces constitute a small, but significant fraction of the price of a bike. However, they are so numerous, that checking their prices is tedious, compared e.g. to googling "Alivio groupset" or "Schwalbe Rapid Rob".

Is there some easy way, given that I know the prices of all components in the numbered bullet points above, to estimate the price, in parts, roughly, of a bike?

    I wouldn't underestimate the costs of these parts, I built a bike this year (steel xc ht - xt/x9 mix). I used fulcrum wheels on my build and costs roughly came out: Drive train 23%, wheels + tyres 26%, fork (RS SID XX) 21%, frame (Cove HJ) 15% and then another 15% on everything else.

  • @DWGKNZ, this is great info! You might consider copying it to your answer as well. In which group do you include the brakes?

  • I forgot brakes, they'd be about 10% of the what I spent above.

I don't think there is an 'easy' way so it will require a bit of leg work and study to get a good reference. It is unlikely that any manufacturer will offer any of these parts at a higher spec level than that of the groupset. So I would:

  1. Choose a few bikes at different spec levels (based on groupset, Acera, Alivio, Deore, SLX, XT and XTR (or equivalent SRAM models)).

  2. Jump on to BikePedia and note down what parts each bike has.

  3. Use Wiggle or Chain Reaction or similar to price the parts.

This will give you some reference as to the price of all the other parts on any bike you are looking at by the groupset.

It's also worth noting that:

  • under SLX level most bikes will have generic parts so take an estimate at quality based on materials.

  • bike companies are buying thousands of these items so with economies of scale will actually be paying very little.

  • unless you are buying factory wheels separately you will have to pay for building.

  • bikes cost more to build than buy complete but you get to choose what you want.


Usually a gruppo is the parts that make up the drivetrain, and sometimes some of the controls. The rest is add-ons that don't have to match to work together, although this is becoming more true for drivetrains as well.

You'll see that higher end parts outside of a group can come in "lines" too. Look at any major manufacturer and you can see this, e.g. RaceFace Atlas.

As far as wheels go, there's not really a standard pairing that's going to allow you view those with anything else. Some companies have partnerships with wheel makers and you might see groups that way, but it's pretty rare. The reason for this is that often times wheels are built with hubs, rims, and spokes from different companies or different brands.

Last, but not least, don't forget that a groupset is put together by a brand. They're not going to give you a deal on someone else's stuff if they can't make money on it.


You could call the collection of groupset and other parts minus the frame and fork a build kit. There are different build kits available to build up a frame in to a complete bike. Some may or may not include a seatpost and saddle or wheels.
