Answer: Yes, but additional spacers are required at the mounting location. Alloy Helix rings require an additional 1mm spacer and steel Helix rings require an additional 2mm of spacers.
Details: e*thirteen UL and SL chainrings were designed for use with XCX, TRS, and LG1 Cranksets. Helix chainrings were deigned for use with Helix cranksets. UL and SL rings are 1mm thicker than Helix chairings at the mounting location. Each Helix Direct Mount ring is supplied with a 1mm spacer which should be used when mounting Helix Direct Mount rings to XCX, TRS, and LG1.
The following spacer assemblies should be used with Helix Direct Mount rings on e*thirteen cranks:
- Helix Direct mount ring + 1mm spacer included w/ Helix direct mount ring.
- Spacer should be installed first, then chainring.
- Helix Direct Mount Ring + 1mm spacer included w/ Helix direct mount ring + 3mm of chainline spacers included with and already installed on crankset (Generally 1 x 2mm and 1 x 1mm).
- See charts below for ring/spacer configurations.
- Helix Direct Mount Ring only.
Chainring / Spacer configurations for alloy Helix Plus and Helix Race rings when used with e*thirteen TRS and LG1 cranks with adjustable chainline*:
*For steel Helix ring install, add an additional 1mm spacer between the crank and chainring.
Answer: All current chainring designs (Helix, Guidering SL, Guidering UL and E*spec) are compatible all 12s chains on the market which we have tested.
One exception is the SRAM™️ FlatTop™️ chain. This chains unique outer plate shapes limit it's compatibility to our chainrings which are 34t or smaller only.
Super boost compatibility requires one of our cranks with the adjustable chainline feature (such as the current Generation 3 alloy cranks or the current Generation 4 Carbon cranks). You would then use one of our UL (-5mm offset) rings with the ring in the outermost postion and the 3mm of chainline spacers placed inboard of the ring.
e*thirteen cranks without the adjustable chainline feature such as XCX and older generation carbon and alloy cranks are not super-boost compatible./hc/en-us/articles/360028692251-What-chainring-do-I-need-for-super-boost-
The telltale sound of a worn front ring is often a grinding noise which in some cases can be felt at the pedals under load while climbing in easier gears. So, how long should a ring last? That's not a really easy question to answer. Read below for more.
There are a large number of variables that go into how long a chainring will last. This makes it difficult to give a specific number of hours or miles before needing replacement. Some of those variables include riding conditions, chainring size, and drivetrain maintenance.
With the advent of modern 1x drivetrains, chainrings do need to be replaced more regularly than when 3x or 2x systems were the norm. This is due to wear occurring only on 1 ring rather than being spread out over 2 or 3 rings. Additionally, smaller 1x chainring sizes are also common which also increases wear speed - a 28T ring will wear about 15% faster than a 32t.
Also keep in mind that with smaller front chainrings, there may be cases where you will need to replace your ring due to wear before your chain is worn to a point requiring replacement.
The best thing you can do is keep your drivetrain clean & well lubed and regularly check the chain for wear.
