I own a sirrus comp specialized road bicycle. I need to purchase a new back wheel/rim with hub. I can't find a duplicate of the exact wheel on the internet. So I will have to purchase an wheel from a different vendor. Can someone recommend an alternative wheel? I certainly cannot afford zip wheels.

The wheel has on it some numbers like 622 X `4C.
Also SIRUS 460V.

Based on that information, I don't know where to buy a similar wheel? Can someone help me out? Do I need more information which may or may not be located on the wheel/rim?

Normally I would say any road bike rear wheel that takes a 700c tyre but I suspect your rear drop out spacing may be 135mm, standard road bikes are 130mm, measure the drop out spacing. The type of brake the bike has is also important is it disc or rim?

Thank you for the help. Can you tell me what rear drop out spacing is?

And I suspect that " 622 X `4 " is really " 622 X 14 ".

Given your apparent lack of bicycle nomenclature and dimension knowledge, I think you would be well advised to go to a good bicycle dealer to get the proper wheel.

+10 buying parts off the Internet is best suited for someone who knows exactly what they need. If you are not positive you can end up having to return items and hassles. Really hard to go from no knowledge to adequate knowledge via the internet.

Head to a bike shop and benefit from their knowledge. You'll pay a premium but you'll get all your answers and the right wheel.

Determine drop out spacing.

Disc or rim brake?
Internal rim width?

Usually that type of bike uses 135 mm rear spacing.
