It's a bit far for me Niel, but on something else, but still on mountain biking, I keep on snapping my bike chains, I suspect due to me changing gears while standing at times, could this be? I keep the chain well lubed at most times.

Thumelo

The main cause of chain breaks is a condition known as cross-chain. Say you have the front crankset on the smallest gear and the rear cassette on the smallest gear. This constitutes a very skew pull and puts immense strain on the chain. It also can cause premature wear on the chain link ends, which could cause a chain pin to drop out and hey presto, chain break!

You should also look at if you are in the correct gear for the gradient you are on. I recently read somewhere that (and this sounds logical but most of us never think about it!) you should adapt your gearing to the gradient of the terrain, for instance small gear on front crankset for steep klimbs, middle gear for less steep ones and the large for level and downhill runs. The rear cassette, you vary accordingly (keeping in mind to prevent selecting a cross-chain combination.)

Besides the fact that in the wrong gear you (and the drivetrain) have to work harder, you can injure yourself (especially knee-joints take a hammering!), so switch gears - that is what they are there for!

Read here:

I went to my LBS yesterday because I noticed a funny sound coming out of the chain when my gears were in the 1 position at the front (left hand shifter) and 7 in the rear (right hand shifter). The mechanic told me that extreme positions (such as 1-7 or 3-1) should be avoided as they can put undue stress on the chain. I wondered if this were true or the mechanic was making an excuse to avoid fixing my chain.

Looking for an answer online I found this on Yahoo answers - does it make sense to you all?


If it's a 21 speed bike - that's actually a mis-nomenclature. There are NOT 21 "usable" gears. There are 13 "usable" gears. 2nd gear on the left or front shifter is used for most occasions. While in 2nd on the front - use any of the rear 7 gears. For uphill climbs - use 1st gear on the left or front shifter but ONLY gears 1,2 or 3 on the rear. For fast or downhill conditions - use 3rd on the front or left shifter - but ONLY 5,6, or 7 on the right side or rear shifter.

This prevents the chain being placed at too severe of an angle - known as "cross chaining". Cross chaining the bike puts too much stress on the chain causing premature wear not only on the chain, but the gears & derailleurs."

But I am sure I could find many more of the same elsewhere on the net.

Hope this helps.

I see Hoppy is on a roll here :lol: , but what you posted makes a lot of sense and have been trying it. Maybe it's time they make auto boxes :mocking:
