Dingle Dangle ?

Most likely you are wondering what is a Dingle , well there is a Dingle peninsular in Ireland which is famous for it's pies which contain lamb, onion, carrots & celery  , pictured below are the two items in question





The other type of dingle that is more relevant to this blog is a double single speed bicycle , how does that work ?. Here is the recipe for making a  dingle . 

Take one single speed bicycle and count the number of teeth on the front chain wheel in my case that was 33 T and then count the number of teeth of the rear cog which is 16 T and add them together to give you the total which equals 49  , then chose another gear combination that equals the same number . I chose 36 T  and 13 T just because I happened to have those spare cogs in my workshop. Hopefully your crank set will allow the use of another front chain ring, in my case I just removed the chain ring guard and replaced it with the 36 T chain ring and my rear cassette style hub allowed me to stack my Chris King 16 T cog and a Surly 13 T next to each other without any spacers due to the fact that the Surly cog has a wide base and was designed for stacking next to other cogs without using spacers . Of course when you need to change the gear ratio's you need to remove your rear wheel and manually move the chain to the other set of chain rings . 




One thing you have to take care of when using this recipe is that all 4 of the chain rings / cogs are in the same condition ideally they should all be brand new , I had slight chain tension problems due to the fact that the Surly 13 T cog is worn out and the front Shimano Zee 36 T was brand  new ,which meant swapping the chain over did not keep the same chain tension. But for me it was just an experiment to see if it was possible.  Pity it's a bit late as I quite fancy a dingle pie right now !
