About Chain Devices & Bash Guards
Chain devices fit in various places around a mountain bikes transmission and help to eliminate chain suck and chain slap when riding over rough terrain or landing from big drops. There are a number of fitments, some frames have ISCG mounts which are lugs on the drive-side of the bottom bracket shell and allow direct fitment to the frame, other chain devices fit in between the bottom bracket and frame and require a specific bottom bracket with a larger drive-side cup, and finally there is the type that clamp around the seat tube in place of the front mech. Also within this section you can find single speed chain tensioners which fit in place of the rear mech and take up any chain slack.There is also a selection of wheel tugs which stop you pulling your wheel over in horizontal dropouts.

Product Q & A
Ask your questions and share your answers.
Anyone used these on a Charge Plug or know if they fit the Charge Plug frame? Particularly the frame sized as 'small'.
Many thanks in advance
i have a single speed MTB and don't want to rode the wrong size.
Also, it's also the width of the part that will slot in the dropout around the axle.
See photo, as it's much better to explain and you can't see it from the wiggle product image.
The wiggle photo by the way is the 14mm version.
I bought the 10mm (the attached photo) and there are no spacers coming along with them.
The 14mm will certainly not slot into a 10mm dropout, so you'll need to measure your axle to make sure you get the correct one.
They will allow you to pull the wheel back symmetrically although you'll need align it yourself.
I'm assuming your dropouts are slot dropouts. If they aren't this won't do any good.
Most of the time, one only is really necessary as the wheel could mostly only move from the drive side, where the chain is in tension.
The chain tugs (or the chain tug if you use only one) will stay on the bike, slotted in the frame dropouts, and pressed against them by the wheel nuts.
you do need to make sure you have enough space to put them though, as they are usually made for horizontal dropouts and there is loads of clearance with these. Not so much with vertical dropouts.
