Single chain ring conversion

paul_stelling

I have been having issues with my rock hopper pro evo gears it is fitted with sram x7 the problem occurs when I have chain slap the rear derailleur seems to stay forward and chain goes really slack . I have to then free off derailleur by hand as chain has all doubled up . I have mentioned this in an earlier post but I was wondering if it my make sense to change to a single chain ring conversion. My current set up is 10 speed 11 36 cassette long cage I believe. Is it just a case of replacing front chain ring with a 32 or 34 narrow wide chain ring then shortening the chain to suit or will I have to change rear mech as well. I just want to make the bike easier to ride on trails with less to go wrong . Chain slap related issues have really been taking the enjoyment out of my riding lately.

I'd solve your problem in the other post first.

Well agreed with cooldad's point but in answer to your question - no.

Because you can also use a 36 or 38 NW. This is all dependent on you and where you ride and not the bike itself. And you also may need to sort out the chainline if the front is a 2X. Use the middle if it is a 3X. For chain retention the NW alone can be enough but for downhill then a type 2 derailleur - with a clutch and on / off lever can help as well as a retention device. The addition of a bash guard can mitigate other problems but may not protect you from sustained machine gun fire or the response from a rhino if you have just given her baby daughter a good kicking.

You think that you might have a long cage - you should work out what you have to see if the set up you are proposing has the gear capacity - an easy calc.

But going back to it; if you are having problems with chain slap then don't just change the front to NW.
