A200 CW Alloy 19X26

 

If you are not going to run a tubeless system conventional rims might be the best choice.  The tubeless compatible wheels have a raised section on the inside shoulders which restricts bead movement.  They do this to help prevent the tires fro blowing off in the case of a flat.  The problem is that they make it more difficult to install tires.  The bike industry currently does not have standards so tire companies vary the size of their beads considerably and there is no standard for a rim maker to adhere to.  That is being addressed by the industry but we are still years away from a standard.  Note these are not "wide" rims.  They are the old standard width of 19 mm.  Actually, this set has a 22 mm wide front and a 19 mm rear.

 

Size: 700C Clincher (normal road bike)

Weight 1650 grams with brass nipples and 1600 with silver (without skewers or rim strips)  weights can vary by about 50 grams a set due to rim, spoke, and hub weight tolerances.

 

Rim Material 6066 Alloy - machined braking surfaces.  Sleeved seam.

Drilling: 20 hole front and 24 hole rear

Rim Weight 450 grams

Rim Dimensions 26 mm high 22 mm wide front 19 mm wide rear

Rim ERD 593 mm

 

Spoke Length Front:  276

Spoke Tension Front: 130 KGF (on a Park Tensiometer 20

 

We use Loctite 242 on the non drive side spokes and on the front spokes during the building process (no lubricant).  On the drive side rear spokes we use a lubricant to build (nothing special - just something slippery) and after the build put some Loctite 242 in to finish them off.   The Loctite 242 will make the spokes harder to turn but will not sieze them.

Black nylon.  If you are going tubeless you need to buy the Stan's rims strips.  These will not work for tubeless applications.

  

With the wider rims, you can use pretty much any tire width you want - from 19 mm all the way up to over 30 mm.  I like 25 mm wide tires simply because they hold more air and are more comfortable.  23 mm tires are probably the fastest and are the most aerodynamic.  As you get bigger tires, the limiting factor is the frame.  Typically the tires will first rub on either the brakes (on the top of the tire) or with the rear tire hitting the seat tube.  Most road bikes will fit up to 25 mm tires, a few bigger ones, and many won't even fit a 25 mm tire.

 

The rim is 25 mm deep but the tubes rests in the rim cavity.  I suggest using tubes that have valuve stems at least 48 mm long or thereabouts.  You will need a presta valved tube (which is by far the most common or road bikes today).

 

With the wider rims you can generally run at least 10% less pressure than with a narrower rim because the system holds more air.  Less pressure is better because you have a bigger tire patch and will roll over the bumps in the road instead of bounce over them (it's that sidewall flex that gives you better rolling resistance).  Most people run too much pressure in their tires because they believe they are faster (and they feel faster at first).  If the roads were perfectly flat that would be the case but they all have lots of bumps so lower pressures make sense.  Generally speaking a 160 pound rider should be around 80-90 psi in the back tire and 75-85 in the front. If you have been running higher pressure you will immediately notice how much more comfortable the ride is and how much better the bike handles around corners.

 

When you receive your wheels it will include a package with the extra spokes, skewers, a spacer (if a Shimano-Sram cassette is ordered) and some documents.  The documents will list the builder and on alloy wheels a serial number (which is under the rim strip near the valve hole on both wheels).  Also included is a spec sheet showing the type and length of spokes used and the spokes tensions for your wheels).  There is also some maintenance info and whatever else I want to throw in there along with a copy of your invoice.  We keep a record of your info here so you can contact us with either your invoice number (preferred), serial number (also OK), or your name and we can pull up your records.
