A bicycle Carbon 29er rim is set with a circular metal rim component and at least a reinforced resin material.Annular metal rim components include:annular tires attachment part,suitable for tire installed on it;The first ring wall part;The second ring wall part;As well as the inner ring wall part,will be described in the first and second ring wall parts connected,and multiple formed in the inner ring wall part of the spokes attachment to speak.At least a reinforced resin material attachment on the annular metal rim components are described,in order to make reinforced resin material stated from the first to the second ring wall sections across the inner ring wall ring wall part extends continuously,which covered the first and second ring wall part of the surface area and around the spokes entrained openings of the inner ring wall part of the external surface area.

Generally speaking,carbon fiber as bicycle material has the following features:

1.Light weight:1200 grams of carbon fiber highway has been everywhere.Due to the quality of the carbon is only 1.6 g/cubic centimeters,so make about 1 kg of frame is not the dream.

2.To absorb impact performance is good.The carbon fiber can effectively absorb vibration,and keep good rigidity.This characteristic makes it a good competition level material.

3.Can make all kinds of the shape of the frame.And general manufacturing process of metal frame,carbon fiber frame is commonly to make mould first,then pay in mould on carbon fiber,finally the cementation with epoxy resin.This process can make use of aerodynamics for the wind resistance tiny frame.
