How is rear hub spacing measured?
Hubs need to match the frame or fork they are used in. The spacing of a frame/fork is measured from the inside surfaces of the dropouts, where they come into contact with the locknuts of the wheel’s axle.
How tight should a rear hub be?
150 in/lb is about standard. If it is not tight it will allow the rear wheel to move around and it ties your rear triangle together. Basically the whole back of the bike will feel sloppy. When you tighten an axle it will squeeze your hub and load your bearings.
What size is a boost rear hub?
12 x 148mm
Boost hubs use 15 x 110mm front and 12 x 148mm rear spacing. This means the hub flanges can be set wider apart to increase the lateral stiffness of the wheel, but it makes Boost incompatible with all the older standards.
How are bicycle hub axles measured?
For this reason we recommend always measuring the frame.
- Step 1: Determine if your frame/fork uses a Thru Axle (TA) or Skewer (QR).
- Step 2: Using a tape measure, measure inside width of frame/fork where hub contacts frame/fork.
- Step 3: Visually identify if your drop-out in open (slotted) or closed.
How do you measure hub size?
The hub length is the measurement through the middle of the wheel (or hub) measuring from end point to end point (or bearing to bearing). You’ll want to make sure to measure through the center of the wheel and not just the outside as there will be space in your rim that will go unaccounted for.
How do you measure hub spacing?
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.
Can you over tighten through axle?
Keeping the axle under-torqued is dangerous, and over-torquing it might damage the fork/frame dropouts. A proper solution would be to adjust the position of the brake caliper itself relative to the disc.
Should I grease through axle?
Applying grease to the actual axles itself is less important, as your wheels rotate on the bearings. However, greasing the axles allows you to more easily slide the axles in and out of the Mountain Bike Frame.
What is your bike’s hub width?
Hubs are generally 100mm wide in front and 130mm wide in the rear for road bike frames; mountain bikers generally use 135-142mm front and rear hubs to allow space for disc brakes, which require extra material on the outer edge of the hub for mounting the disc.
What is the hub bore size?
The outer diameter is the hub bore, while the inner diameter is the diameter of the vehicle hub itself. For example: a hub-centric ring size of 73-67.1 would mean that the wheel center bore is 73 mm wide and the vehicle hub is 67.1 mm wide.
How do you measure a wheel hub size?
The inner measurement of the wheel hub is also easy to measure; remove the wheel and measure the wheel hub outer diameter with a slide caliper. A tape measure or a ruler can also be used for measuring. Measure the outer diameter as accurately as possible and choose the nearest size from the size table.
How does the rear hub work in a Zipp?
The rear hub is optimized for single-speed performance racing with a flange design that yields equal tension on the drive and non-drive side of the wheel. This eliminates torsional deflection through the hub-shell, providing immediate acceleration and flawless tracking through banked velodrome turns under power.
What are the dimensions of Zipp disc brake wheels?
We introduced the 303 Firecrest disc brake wheel set with new front and rear black Zipp disc brake hubs, 24/24 spokes 100mm front and 135mm rear spacing. Note the spoke angles for disc brake wheels are different (lower angles) than regular road brake wheels and the lacing pattern is 1x, 1x front and 2x,2x on the rear.
Where is the fixed gear cog on a Zipp disc?
The Zipp disc track axle conversion kit transforms most Zipp discs produced from 2010 through current models for fixed gear use. Your disc wheel must have a thread-on fixed gear cog attachment on the wheel for the conversion to work. The fixed gear attachment point is located on the opposite side of the wheel from the cassette.
Is the Zipp 900 15mm disc axle still available?
Note: The 2005-2012 Zipp 900 15mm Track Axle Conversion (Zipp part No. 11.2100.027.000) is discontinued and no longer available. See the Zipp Identify Disc Guide to help select the correct Zipp Disc wheel. Be the first to review this product.
