Convert rear hub width 142 mm to fit 135 mm dropouts
5 min read
Asked by: Lynn Windish
Will a 142 hub fit a 135 frame?
As the number suggests, 142mm is 7mm wider than the dropouts on your frame. Also the Surge is 135x10mm, so you have to have either normal quick release or 10mm bolt up, 142x12mm simply won’t fit. If it’s a wheel you’ve already got, check with the manufacturer to see if they sell adapters or a different width axle.
How do you convert a 142mm hub to 135mm?
You can’t adapt 142mm to 135mm. You have to change the endcaps of your hub. The bad news is each hub has specific endcaps, or at least each brand as specific endcaps. The good news is Stan’s most probably have endcaps to convert the 142mm hub to 135mm.
How do I know what size rear hub I need?
If you are unsure of your frame spacing or have an older bicycle, measure the hub width to ensure a proper fit. To do this, remove the rear wheel and use a pair of calipers or a ruler to measure the distance between the inner surfaces of the dropouts.
What is rear dropout spacing?
Quote from video: And through axle dropouts to illustrate how much smoother it is when we use rear dropout spacing to define the distance between the innermost faces of quick release as well as through axle.
Are hub bodies interchangeable?
Almost always, the answer is no, there is no interchangeability between different brands – and often limited interchangeability within a brand.
Does hub spacing matter?
A wider axle means that the spacing between your hub’s flanges can be increased. By increasing the width of the hub flanges you can improve the bracing angles of the spokes in the wheelbuild. Ultimately you can build a stronger, stiffer, and ultimately more efficient wheel.
Will a 150mm hub fit a 148?
148 hubs are really 141 + 7mm (just like 142’s are really 135 + 7mm). Theres a 3.5mm recess on each dropout that the hub axle fits into. If I remember right, the diameter of the axle is 19mm. 150mm hubs do not fit into anything, so usually the diameter will be bigger than 19mm, which is the first reason it wont fit.
Can I change wheelset hub?
Simple answer: yes, but it’s not worth doing. Cost of hub, spokes, nipples and having wheel rebuilt will exceed the cost of a new wheel. Even if you re-use the spokes a new wheel will still be cheaper. Wheel building requires special equipment, expertise and time to do correctly.
Can I upgrade my freehub body?
Yes. You can replace just the hub, but you’ll likely need new spokes, and a decent mechanic will charge $50+ for the job. Unless you have a really nice rim, that’s not worth it. Buying a new wheel makes more sense.
How is rear dropout spacing measured?
Frame spacing is the inside distance between the two fork ends (drop outs), where the wheel fits in. This can easily be measured just by removing the wheel and holding a ruler up to the space where the wheel came out.
How do you work out hub size?
Measure across the middle of the wheel hub to get the diameter. The wheel hub bolt pattern is the number of bolts lugs on the hub and the diameter of the circle in which they are arranged.
How do you size a hub?
Hub Flange Diameter – The distance across the hub’s flange from hole to hole.
Here’s how to measure these distances:
- Figure out the distance between the lock nuts (where the hub sits in the dropouts) – 100 or 110 mm is typical for the front. …
- Take that number and divide by 2.
- Then measure from the flange to the lock nut.
Are all hubs the same width?
Hubs have to be matched to the front or rear of your bike; each will be a different size.
Is ratchet better than Pawls?
Ratchet systems are generally spoken stronger, more reliable and need less maintenance compared to traditional pawl systems. Biggest reason for this is that the power transferred from the drivetrain to the wheel is spread of a larger surface. In general hubs that are “louder” usually have more engagement points.
How do I choose the right freehub body?
Choosing Your Freehub
- Determine the brand: Locate the brand of your existing cassette—most likely it is Shimano, SRAM, or Campagnolo.
- For a Campagnolo cassette, choose a Campy freehub.
- For a Shimano freehub, count the number of gears on the cassette. …
- For a SRAM freehub, count the number of gears.

Can you put a 36 hole hub in a 32 hole rim?
The hole counts must match. You need to order a 32-hole rim or a 36-hole hub. I recommend the latter. 36-spoke wheels are noticeably stronger than 32-hole ones.
How do I know if a wheel will fit my bike?
Look at the sidewall of your tire to find the tire size that will correspond with your new wheel size. On road bike tires, you’ll see a number pairing such as 700×23. The first number (700) is a size which roughly corresponds to the outer diameter of the tire in millimeters.
How do I know what size my hub is?
Quote from video: The first method is the use of a digital caliper. Place the caliper at the bearing locations on the spindle the resulting. Number is the diameter of the spindle.
How do I know if my hub is compatible?
A good way to check compatibility is to see how many teeth your Sram cassette has. If the smallest cog is 10T, it should use an XD-style freehub, but if it’s 11T then it likely uses a Shimano HG freehub. Campagnolo freehubs are compatible only with Campagnolo cassettes.
How are rear wheel hubs measured?
Quote from video: Down into the middle of the hub. Until it touches the bench carefully pull that out and you can very clearly see this hub is 110.
