SRAM 0mm OFFSET Raptor Oval Chainring - UK MADE

NEW UK Made 12speed Compatible RAPTOR narrow wide chainring range

Alternating narrow-wide profile teeth help reduce sideways movement in rough terrain which normally derails chains. Complex precision machined debris gullies help evacuate mud for all weather performance superior to the competition.

A direct mount fitment narrow-wide chainring designed to keep chains securely in place. Compatible with all 9, 10,11 or 12 speed chains, so virtually everything including the new SRAM EAGLE range. These chainrings are designed and CNC machined from 7075 T6 aluminium in our own facility in the UK. By manufacturing products with the highest quality machinery, we can offer market leading quality for amazing value and huge choice of fitment.

Why Narrow-Wide?
There is alot of marketing rubbish and myths about narrow wide rings but in effect they are quite simple. Chains are designed to have sideways movement in them to allow for shifting on a cassette, without this they wouldnt shift. If you are running a single ring on rough ground the chain whips around and can twist sideways enough to come off the ring while pedling. This is because the outer links of the chain leave a larger gap and allow the chain to twist off the ring further than a narrow link. A narrow wide ring has fatter teeth to correspond with the outer links which prevents this excess sideways movement, and therefore prevents the chain dropping off the ring.

This type of ring doesnt grip the chain, or prevent it jumping over the top of teeth, or other magical marketing claim! Tooth height and shape have no effect on performance as the chain only ever touches a small part of the ring - the bit which wears on the face of the tooth in an old ring.The biggest difference between brands is the complexity of the machining to clear mud and debris which causes wear and reliability problems. Our complex and market leading tooth profile ejects mud much more efficiently than our competitors, giving you superior performance in all weathers.

FAQs

Do I need a chainguide or a clutch mech?
Not specifically, but for more intense riding styles you may want to add additional layers of security. Any chainguide requires sufficent clearance to cover at the largest point of the ring.

What is the offset of the ring and what chainline?
The offset of a ring is how much it is dished over from a standard flat chainring, it is used to achieve correct tyre/frame clearance and also to set the correct chainline. A standard chainring is 4mm thick with the teeth central to the ring, so a 8mm offset ring is 12mm thick and moves the teeth 8mm inboard of the standard position.
This moves your chainline to suit your requirements and crankset specification. Different cranksets are designed around different offset rings, we manufacture our rings to follow the manufacturers standard chainline/offset. It is possible to alter the chainline from standard but this can lead to clearance issues so we do not offer such parts. Read the crank manufacturers manual for information

Ive got Boost what offset do i need?
Boost rear hubs are 3mm per side wider than standard. Some manufacturers use a special Boost chainring to move the chainline outwards 3mm to match this, others use standard offset chainrings with a special Boost crank. You need to find out what crank offset type you have and choose the correct model ring to suit. Read the crank manufacturers manual for information

Which PCD do I require?
PCD is the diameter of the bolt pattern, and you need to match this with your crankset dimensions. There are lots of different standards so please dont guess, either measure or contact the crank manufacturer for information. Here is a brief list of common sizes:

64 BCD x4 - Common 4 bolt inner ring
76 BCD x4 Asymetric pattern M8.5 Thread - SRAM XX1
88 BCD x4 - XTR M985
94 BCD x4 - SRAM X01, X1 and GX
96 BCD x4 M8 thread - Some Shimano Triple
96 BCD x4 Asymetric pattern - New Shimano XT M8000, SLX M7000 etc
96 BCD x4 Asymetric pattern M7 thread - New Shimano XTR M9000 M9020
102 BCD x4 - XTR M960
104 BCD x4 - Common 4 bolt mountain bike size
110 BCD x5 - Road Compact
110 BCD x4 Asymetric pattern New Shimano Road Cranks
120 BCD x4 - some SRAM double cranks
130 BCD x5 - Road Standard
144 BCD x5 - Track Rings
Various direct mount spline types as well specific to manufacturer

Please note:

• Ensure you check fitment suitability before ordering.
  
• We cannot accept returns on parts which are used or otherwise marked. You must check you have the correct fitment before attempting to fit, as parts which are not in as new and resalable condition are not refundable or swappable.
• These chainrings are designed specifically for single front set-up only. They do not have the necessary shifting ramps and will not work with double or triple ring set-ups.

Weight:

• 28T - 46g
• 30T - 50g
• 32T - 53g
• 34T - 57g
• 36T - 61g
• 38T - 64g
• 40T - 68g

Suitable for SRAM direct mount spline crankset without a spider. Just bolt on with original fixings, for more information on installation please consult crank manufacturers manual.

Offset:

We offer 0, 3 and 6mm offset in SRAM fitment

Note other brands measure sometimes measure differently please see below for details.

What is the offset of the ring and what chainline?
The offset of a ring is how much it is dished over from a standard flat chainring, it is used to achieve correct tyre/frame clearance and also to set the correct chainline. A flat (0mm offset) chainring is 4mm thick with the teeth central to the ring, so a 8mm offset ring is 12mm thick and moves the teeth 8mm inboard of the standard position.
This moves your chainline to suit your requirements and crankset specification. Different cranksets are designed around different offset rings, we manufacture our rings to follow the manufacturers standard chainline/offset. It is possible to alter the chainline from standard but this can lead to clearance issues so we do not offer such parts. Read the crank manufacturers manual for information

Unfortunately we cannot tell you what your personal bike requires for offset as there are too many variables. Just measure your current offset and buy the replacement to suit your requirements.
