Frequently Asked Questions

Craftworks ENR Frame Warranty

2 year original owner.


What length chain will I need?

We've tested the ENR with SRAM 1x drivetrains with 10-42 cassette.
For a 32T or 34T front chainring, you'll need a 122 link chain.
The longest chain available from SRAM is 118 links, so you'll need to buy two.
Tip: the leftover from the 2nd chain should still be long enough to fit a bike with a 'conventional' drivetrain.


What fork is recommended?

The ENR geometry is based on a 160mm Rockshox Pike fork, with 552mm axle to crown length, and 42mm offset.


Can I run an offset/angled headset?

Yes, the headtube has a 56mm bottom ID, and a 44mm top ID.
Cane Creek Angleset and Works Components headsets will fit this headtube.
The extent of angle will depend on whether you plan to run a fork with a tapered steerer or straight steerer, and whether you want an internal cup or external cup for the bottom headset bearing. We can help you to find the right set for your bike, just ask!


What size dropper posts will suit me?

The required post diameter is 30.9mm.
Due to the necessary location of the upper frame pivot, the insertion length of a seat post is limited to 190mm.
Some shorter riders may have trouble achieving their preferred lowest saddle position.
To assist with dropper post selection, this document shows the compatibility of the various Rockshox Reverb options.


How should I route the brake/gear/dropper cables?

The dropper post cable should be run in the downtube, fed in from top to bottom. We recommend doing this before installing the bottom bracket, to make it easier to reach into the bottom of the downtube to assist the cable with exiting the hole in the frame. The cable then can be fed upwards, directly into the base of the dropper post.
The rear brake hose and gear cable should be run through the top tube and seat stays. We recommend feeding them in from the rearmost hole, through the seatstay, then into the hole at the rear of the top tube, and out the hole at the front of the top tube. Use an old spoke though the hole on the opposite side to help the cable/hose exit from the top tube.


What shock hardware is required?

Some people may choose to run a shock other than the Cane Creek DB Inline.
For those choosing their own shock, the following hardware is required:
Top Eye: 40mm x 8mm hardware
Bottom Eye: 22.2mm x 8mm hardware
The required shock is 200mm Eye to Eye, with 57mm stroke.
Shocks with 'piggy back' reservoirs will fit, but may prevent the ability to fit a drink bottle in the frame.


Can I run offset shock bushings to alter the geometry?

No. The ENR has limited clearance between the rear triangle and front triangle at bottom-out. Any alterations with offset shock bushings may cause the frame members to clash.


What size crankset do I need?

The Bottom Bracket is 73mm wide, with standard threads.
We recommend a Q-factor of 168mm to provide good chainstay clearance.
Required chainline is 49mm (SRAM non-Boost). Shimano equivalent has a chainline of 50.4mm.
Do not use cranksets designed Boost or Fatbike standards.


Do I have to run the custom MRP chain guide?

Yes, due to the rearward axle path, it is necessary for the lower chain run to be held as high as possible with the MRP pulley wheel.
Without the chain being held this high, the derailleur arm would have to accommodate more chain growth through travel, and may not be able to also accommodate a wide-range cassette.
Other aftermarket chain guides are not likely to be suitable, as the ENR has non-standard BB tab positions.


What bearings are required if mine wear out?

The ENR has Enduro MAX bearings on all suspension pivots, so they should last longer than standard bearings.
Nevertheless, if they start to wear out, the following replacements are required:
Upper Frame Pivot: 2x 6902-E , 1x 6902
Lower Frame Pivot: 2x 6902-E
Upper Swingarm Pivot: 2x 6000
Lower Swingarm Pivot: 2x 6902-E
Idler Pulley: 2x 6801


Is the idler pulley noisy?

When new, the idler pulley will make some additional noise compared to a conventional drivetrain, particularly in the lowest gear. The pulley is made of aluminium, and it is intended that that the teeth ‘wear in’ during the first 50-100km of riding. There will be some loss of the anodising during this process. This is normal. Once the idler pulley has worn in, it will remain relatively quiet. As with any other drive train system keeping your chain well lubed will minimise noise.
