Afternoon,
I'm just about to complete the swap to a single 32T ring on the front on my Giant XTC29er. I need to split the chain anyway to remove the front mech, so was wondering if i should shorten the chain length ? (Chain is 1 ride old only as i fitted it last week)
Thanks.
Hard tail or full sus? If it's hard tail then remove your chain and wrap around the chain ring and large rear sproket (without passing through the deraileur) and bring together and add a whole 1" then join. If using a master link put one half of the link in first before pulling both ends of your chain together then add an 1",you may need 2" if you are using a front tensioner as well (you an always remove an 1" easily).
If it's a susser then the proper way is to disconnet the shock and move the rear arm/triangle to the point at which you have maximium chain wrap then size as above.
Or leave the chain as is as it worked before.
HT 29er.
THe chain is the chain i fitted last week on the standard length setup. I just removed the one that came with the bike new (running 3 rings) and replicated the length of that.
Not using a tensioner but fitting a superstar top guide.
