Nuther 2x9 question

vmgscot

I'm looking at dropping my big ring as I never use the darn thing anyways. I'm OK with setting FD stop and sorting chainlength, etc but unsure about chainset protection. Seems I have a couple options... either a 'standard' bashring or one of these 'taco' devices perhaps. What should I consider between these options?

Chainset is M970 XTR and frame as ISCG (Yeti 575).
Cheers in advance

i sure the xtr uses a different bcd than the common 104..

i was looking at going for a xtr and running 2x9 in the end i wen for a truvativ noir crank and dropped the big ring and replaced it with a straitline one..

i cant remember what the bcd is on xtr..

edit a quick look on google tells me that your model m970 has a bcd 104 so in theory you should be able to swap the big ring for a bash as i did on my noir crank... if you lucky you wont even have to change the bolts...

XTR 970 is 104 - the older 960 was some oddball 146

You don't have to have a bashring.

bashrings are cool and make you go faster


I'd ebay for one, should be able to get one sub £10 if you're lucky or wait a bit.

Most alloy bash's use standard bolts, the plastic ones (Shimano/E13 supercharger etc) are thicker and need longer bolts to fit them (CRC do the raceface ones for about £5.99), the alloy ones tend to be lighter than the plastic ones.

I use a bash as where I ride we get lots of logs across the track and often need to push the bike over, with a bash I don't have to worry about the chain/ring hitting the log.

Absolutely, and I have one because I am both cool and fast. But as for protection - triples don't have them, and you are more likely to bash a big ring.
So if you are cool, get one.

Have bashrings and tacos on four different bikes I think I prefer the tacos for single ring setups but the bashrings are fine if you are just losing the big ring from a triple.

Race Face Light bash ring is a work of art it weighs nothing and feels as though it's made of plastic and ideal for trail riding. As above the plastic rings eg Supercharger are plastic manhole covers designed with bomb-proof protection first and foremost but they do work if you're not too bothered about weight/looks

Also have e-thirteen LG and LS guides they are very nice superb engineering and totally unobtrusive in use. I like them a lot.

Thanks for replies.... I'm not worried about weight... in fact, my 'trail' bikes have gotten heavier and heavier with each new bike I buy (not that often) .... I'm sort of liking the idea of the dual ring chain device with taco.... but we'll see what I can afford.

Thanks again....

Simplest chain device for two rings is a blackspire stinger, and a bashguard, and it works like a charm.

I have got a stinger & bash guard on my trail bike. Great set up, never drop a chain.
