The H screw should be adjusted so that when shifted into the smallest cog (highest gear) thederailleur pulley sits directly underneath the smallest cog. Note that this last method only really applies to non-shadow rd derailleurs and cassettes smaller than 28T. Yes chains snap, almost always it is due to a poor shift under load. Its surprising what 1mm extra will do we started with two spacers and it was too much. So, if youre installing it yourself and its trimming into contact with the frame, stop tinkering and add a spacer. Shift carefully during this process! Sram NX / GX eagle chains are a huge step down re longevity ZFC does not recommend these chains at all. Again the higher level eagle components are very, very expensive, and of course riding off road presents huge challenges for many lubricants. While this guide isnt as durable as the plastic ones included with SRAM groups, its also not plastic, which we appreciate. These will be on one side of the chain only, and that side should be facing out (away from the frame). They are fine for 4 to 8 hour enduro / XC marathon length. I set on up today and we have done a few at Trek. You then put the chain on the largest chainring and route the chain through the rear derailleur. Use Campagnolo record 12spd chain as your race chain (or one for training and one for racing if you dont like losing watts in training either). Break the chain at your measured length using the chain breaking tool. The B screw adjusts the vertical distance between the derailleur pulleythe rear cassette rear cassette. Make sure the shifter is shifted to the highest gear (smallest cog) by pressing the small shift release lever repeatedly, then install a new cable in your shifter. derailleur pulley sits directly underneath the smallest cog. For the full data and test wrap of the chain test project refer to that tab on website or click this link here.. Finding the best bicycle chain: What over 3,000 hours of testing revealed, YBN SLA Ti-N Silver, YBN SLA Ti-N Rainbow, YBN SLA Ti-N Black, YBN SLA Ti-N Gold, SRAM AXS UFO, SRAM AXS Road Red, SRAM AXS Road Force, SRAM Eagle XX1 (Rainbow), SRAM Eagle XX1 Black, SRAM Eagle XX1 Gold, SRAM Eagle XX1 Copper, SRAM Eagle X01 Silver, KMC x12 Eagle UFO, KMC x12 Eagle Gold, Shimano DA/XTR (116 Link), Shimano DA/XTR (126 Link), Shimano DA/XTR (138 Link), Shimano XT, Campagnolo Record, Ceramic Speed UFO, Fully Optimised Race Prep, Ultrasonic Clean & MSpeed Wax, Ultrasonic Clean & Silca Hot Melt Prep, Ultrasonic Clean and AbsoluteBlack Graphene Prep, US Clean Rex Black Diamond / Revolube, US Clean + Rex BD + Race Day Drip Treatment, None. Yep thats right, Campy road chain! You can check out Zachs initial review of the new Dura-Ace group for more. Yeti SB115, Santa Cruz Blur, or NEITHER?! Shipping to ALL countries outside of Australia is now a flat rate of $65. You do however have go fast options for sram eagle / sram axs eagle ie the YBN 12spd is a brilliant plug n play many watts faster chain vs sram eagle chains both are an 11/128 standard chain of same width etc. They are astoundingly long lasting. Shift into the middle of the cassette, then turn on adjustment mode. The extended inner links were designed to provide unparalleled rear shifting performance for shimano system, it seems to improve on srams system too. Apologies shipping rates out of Australia are high due to ginormous continent with relatively low commerce! Want to buy me a coffee instead? In the video below, youll see us run it through the gears various ways, showing you the automatic trimmingincluding the rear derailleurs auto trim that youve probably never seen before. Their 12 speed record chain did test with a measurably lower lifespan vs their 11spd chain however, so ensure keep a regular check on chain wear due to cost of Record 12 speed components. At the time of writing this update i have been testing a myriad of YBN 12, XTR 12 and Campy 12 on my sram eagle drivetrain and all has been groovy across the lot of them, and for most of customers field test whichever option they have tried has been great, however there have been the odd case of campy 12 not shifting well, or XTR 12 not running well on the 50t cog. Size the chain so that the derailleurs jockey wheels are at 90 degrees to the ground. They do work perfectly with sram pulleys and cassettes in fact personally I think the XTR 12spd works better. I have seen numerous customers whos NX / GX chain is at 0.5% wear mark within 5 to 10 rides on factory grease. Between each of these steps, youll need to switch out of adjustment mode in order to shift like normal. Straighten as necessary. Route the cable through the shift housing to the derailleur. This is what youll use to connect the chain, once it is threaded on the chainring and the derailleur. Have the two chain ends meet at the large chainring, and then add two or three links, depending on the zero point shown in Shimanos image below: Basically, if the point where the two chain ends meet is the end of an outer link, add three links (left image). Then use the Shadow RD method described above. Im running 8070 Ultegra Di2 Derailleurs with GRX shifters and a SRAM Red crankset/rings on my bike and it appears to do everything just as quickly. So even if not concerned re friction losses for racing it is important to remember that higher friction losses due to an average / poor lubricant & maintenance will correlate directly with drivetrain wear rates. Measure off where the chain meets and then count two pin-holes of extra chain links. Check chain length with suspension compressed. If its a Transition then they made a new hanger that will work with it. If yourderailleur hesitates when shifting into bigger cogs (lower gears). TheSLX derailleur on theZulu Four HEIR is fairly easy to adjust. Some chains have an additional option to be Ceramic speed UFO treatment / Rex Black Diamond / Silca Hot Melt prep. Adjust the low gear stop screw so that the upper guide pulley is centered on the largest cassette sprocket. Prior to that, Tyler launched and built multiple sports nutrition brands and consumer goods companies, mostly as an excuse to travel to killer riding locations throughout North America. Chain length is Critical to the success of your setup, so inspect your chain length carefully before cutting the chain! And, hes totally gone down the NFT rabbit hole. However, i have had some customer feedback that for some set ups the campy chain has not shifted as well, i can pin down and explanation for this as dimensionally it is basically identical as eagle chain, and it shifts brilliantly on my bikes. You may not ride around in the 4810 much, so maybe it is only an average of 2 to 3 watts being lost vs running larger rings / larger cogs it is still a move in the wrong direction with regards to drivetrain efficiency. The biggest improvement was a direct mount derailleur hanger. My XT 12 speed actually needed a longer b-screw fitted to get correct alignment. The derailleur isn't compatible with the hanger, Shimano didn't seem to do a lot of testing with existing hangers to ensure compatibility. For Eagle drive train users to consider this option you will need to swap your sram eagle compatible chain ring to a shimano XTR 12spd compatible chain ring. Whilst Sram AXS rings / cassettes are indeed impressively hard wearing, it will still only take a poor lubricant choice (there are plenty of powerfully marketed, mainstream lubricants that are not that great, at all) as well as being lax on chain wear checking and in short order you will cause considerable wear to these expensive components such that they will not accept a new chain. Do you have a smaller cassette? Note that suspension sag / chainstay length growth will change the position of the derailleur when the suspension is weighted. Whilst it is not as fast as XTR or Campy 12, it is still multiple watts faster than Sram Eagle chains at 250w load, a gap that will basically double every extra 250w. Shimano uses a special connecting pin that has a break-away guide that comes with the chain. For Shimano chains in particular, pay attention to the text and logos on the chain. What is a "non-shadow RD", you ask? AXS wireless in a very impressive system in many ways, however ZFC has to be a straight shooter here the move to 10t cog and smaller chain ring sizes is a step backwards regarding drivetrain efficiency. You use the front shifters paddles to adjust the front derailleur, and the rear for the rear. The YBN 12 is the safest plug n play fast race day chain swap, but note whilst it is much faster than the eagle chain, it is still bit slower than record 12 and likely also xtr 12. If you are already on XTR 12 speed you have no problems. Your first thought is probably thats nuts, will it be strong enough? The front derailleurs tuning starts from the outside in (see below for more on this), with the goal being a 1mm gap between the chain and the outer plate when the cassette is on the smallest cog. Our bike was initially missing a simple 1mm spacer between the crankset and bottom bracket, which ended up allowing the front derailleur to contact the seat tube prior to tuning. YBN SLA Titanium Nitride 5th Gen All Colours. If not careful an AXS road bike can have running costs similar to a Ferrari, or with a top lubricant choice / maintenance and chain wear checking the hard wearing AXS components will last a very very long time, and you will be getting some watts back. We checked them vs GRX and AXS and depending on the rider SRAM is fastest. If you are riding, youre awesome and ZFC is here to support you with best advice and ensuring your hard earned $ go towards products that are not just marketing hype. Make sure to use a metal pick, toothpick, or other pointy object to flare the inner sheath of your cable housing at each cut end. Wolf Tooth and Absolute Black make great after market XTR 12 compatible chain rings to fit Sram / Race face cranks etc. If you have bought an NX / GX chain equipped bike great groupset, but swap that chain out asap. Well, all 10-speed Di2 derailleurs and the first generation 11-speed Di2 road derailleurs: If youre using one of the older Di2 derailleurs, the chain sizing method depends on the cassette installed on the bike. The inverse is not true. For the best independent information on chains available, refer to detail in product description below. Should you wish to support the site, please use the site affiliate links. Verify that the chain will not overshift into the spokes by gently pressing on the downshift paddle while pedaling the cranks forward and watching the chain movement. Theres no confusion with Easiest and hardest. NOTE: SRAM AXS ROAD drivetrain MUST RUN SRAM AXS FORCE OR RED CHAINS NO AFTERMARKET / OTHER CHAIN TYPES ARE COMPATIBLE Axs road is a much more narrow chain and has oversize rollers you MUST run axs road chains, YBN / CAMPY / Shimano 12spd chains are NOT compatible with AXS Road 12spd. Stay tuned it will get done, in the interim ZFC is certain it will a very long lasting chain as claimed however do not take this a green light to be lax on lube selection / maintenance as the cost penalty and watts loss penalty for doing so will be very high indeed. For some systems there are options, for other systems your best option is simply to ensure you are running the best possible lubricant choice & maintenance.
