DC AFAM ALWAYS QUALITY WITHOUT COMPROMISES
DC wants to offer you today’s highest quality standard. Continuously made efforts to improve the ‘chain drive performance’ off your bike, has resulted in lighter chain with increased tensile strength and higher limits to shock resistance.
A light chain with better features guarantees you more transmission efficiency. Less power loss, less weight and a more elegant chain increases the transmission efficiency.
Less noise, more mileage and less worries increases the comfort of the rider. With DC chain you will certainly notice an extended lifetime, smoother gear shifting and less maintenance. DC has a well balanced range to suite every motorbike from your classic bike to your high performance sports bike.
STANDARD diameter of the rings for chain s 520/525/530 measure 10.16 mm, but the request for higher and higher quality in the market is leading to a gradual increase in diameter. Pins larger in fact reinforce the chain, thus contributing to increase also the size of the seal rings and the bushings extruded. Also in this case, the producers of chain and sprockets must deal with all the difficulties dictated by the search of the joint perfect between the teeth and the diameters of the various chains.
Today it is possible to find in the rings with a diameter between 10.10 mm and 30.10 mm. The DC quality allows the chains also perfectly suited to sealing rings with a diameter of 10:20 mm, to which are added the chains made with the same amplitude in diameter.
But let us see how DC is able to always choose the best chain for each individual application:
Standard diameter (Do): Do = STEP / sin (180 / Z)
Tooth diameter (Df): Df = Do-R
Here it is explained why DC uses different types of rings-QX depending on applications.
The off-road off-road presents QXring very flexible and resistant to wear.
In response to the multiple exposures to the contact with mud, stones or sand, DC has studied a model of flexible chain, whose mesh is always able to ensure maximum performance even in extreme situations, maintaining long the liquid lubricant present at 'interior of the individual mobile connectors that make up the shirt. (DC520MRX-G)
In relation to motorcycle touring then, the market demand is even greater: these applications are in fact designed to ensure even higher mileage than the Sport bike. This is made possible thanks to the special ring-QX, which marks the bands of series 520/525 / 530MZX-G.
For off-road, DC has instead scheduled transmission chains with a diameter smaller than the standard and measuring 10.16 mm (10.10 mm - 10.14 mm).
It is our own experience to tell us : to minimize the space between the individual components of the chain prevents the penetration of dirt , guaranteeing longer perfect operation of the drive train ( DC520R1 - G / DC520MDX6 - G / G - DC520MRX ).
The entire range of DC chains available in the catalog is available in all sizes and length of stride.
The unique design of the rings QX is designed to constantly maintain a high degree of lubrication in the joints , thus prolonging the life of the chain , lowering the cost of maintenance intervals .
With mobile connectors ring QX , DC - CHAINS chains have also
The goal of DC-CHAINS is to offer the highest quality standards on the market today. The its transmission chains are aimed at improving driving performance of your motorcycle, proposing chains lighter but by the very high load resistance.
Weight reduction and improved quality of the chain also mean less power loss of the bike and are a sign of guarantee greater effectiveness of the entire transmission system. A chain more silent and able to withstand a higher mileage surely indicates the high degree of reliability of the products DC-CHAINS, on which the pilot knows he can always count.
With chains DC-CHAINS will notice a marked aging of the chain, a greater facility to change and a considerable reduction in maintenance intervals.
Through its wide range of products, the brand DC is able to meet the needs of any model of bike, from the most classic to the purely sports: its chains are in fact multiple applications, ranging all-around in the world of cycling.

DC CHAIN SPROCKETS KITS are a clear example of the very technology that characterizes these two great brands: their revolutionary design to ensure maximum efficiency of each component of the transmission system. The constant search for "QUALITY WITHOUT COMPROMISE", DC-AFAM submit each product to strict quality control, taking care of every single step in the first person.
DC-AFAM knows that the relationship between STEP and DIAMETER in the chain is the basis of the proper operation of the crown: the PAS chain 520/525/530, for example, precisely measuring 15,875 mm and has a tolerance of between 0.05 % and 0.4% (ie from 15.8829 mm to 15.9385 mm).
Precise joining between the crown and chain depends entirely on the tolerance referred to each single step: just think that in the case of a crown 20 teeth, a difference of 0.0278 mm per tooth generates a discrepancy total of 0.5560 mm: ie 20 times higher than the initial one.
In the case of the chain, the tolerance referred to by technicians DC-AFAM ranges from 0:15% 0.25%. For a length of 15,875 mm for example, the margin of tolerance is therefore quantifiable between 15.8988 and 15.9147 mm mm.
In conclusion, the products DC CHAINS ratio tolerance between the components is equivalent to 0,0159mm / 2 = 0.008 mm x 20 mm = 12:16.
Not bad, right?
DC-CHAINS consist of a wide range of CHAINS- SPROCKETS , in order to better meet the needs of the individual rider and guarantee the best performance of your motorcycle, both for normal and intensive.
STEEL REAR SPROCKETS
Steel rear sporckets are made entirely of steel C45N and teeth have a hardened coating which makes them even more resistant to impact and wear.
The high quality of the crowns united to that of the chains, guarantees a higher mileage to the average.
Perfectly circular, flat and concentric, these sporckets have spline unique wich makes them the best available today.
DC-AFAM uses the best steel alloys available on the market. The minimum margins of tolerance and the profile of the teeth tested to withstand intensive use guarantee all the quality of the brand DC.
