MadNick1.2 Posted October 19, 2009 Report Share Posted October 19, 2009 Hi All,In was thinking about getting one of thesehttp://www.tartybikes.co.uk/product.php?pr...p;category_id=1from Tarty bikes.It says near the bottom when using a 1/2" chain that it will scrub on the bashring which i can believe due to my middleburn pro trials scrubbing.It also says that you can use washers to stop this from happening, but my concern is will using washers to make the chainring further away from the bashring weaken the drivechain?The weight save is decent from the middleburn which is 184g to the TNN's 43g.So i am temped to get the TNN bashguard but are my concerns anything to worry about??

forteh Posted October 19, 2009 Report Share Posted October 19, 2009 It wont significantly weaken the drive train, the force through the cranks is transmitted via the 5 chainring bolts, these are sufficiently strong enough to be spaced out by a mm or so Just make sure that you use long enough bolts in order to get a full length of thread in there, that will cause more of a weak point.
