trials_noob Posted August 8, 2006 Report Share Posted August 8, 2006 Hi there,I have been reading a few topics about freewheels and being new to trials I have no idea what they do or how they help your riding. So can someone please explain to me what they do,how they help and what differences are noticed with them?I have tried searching and went through 6 pages of results but couldn't find anything that said what they did and how they helped.Thanks Quote Link to comment Share on other sites More sharing options...

Mark W Posted August 8, 2006 Report Share Posted August 8, 2006 Basically, it's what makes the 'click' sound when you roll along without pedalling. On mods, the freewheeling part of the bike is on the crank arm, and it just screws on. You have a set of pawls and springs mounted into the freewheel's body. The springs push the pawls (little metal arms) up, and away from the body. This makes the pawls pivot up so they mesh into a ratchet (like little triangles cut out of the metal, basically) which is on the shiny silver driveshell. The driveshell spins around the freewheel body one way, the clicking sound are the pawls being forced back up into the ratchet bits by the springs. When you pedal, the pawls are pushed into the flat faces of the ratchet points, and this engages the chain. There's also a thread in the FAQ section of Trials Chat which has some pretty detailed pics of a White Industries Eno freewheel being stripped 'n' cleaned which may help you out too Quote Link to comment Share on other sites More sharing options...
onzatprodude Posted August 8, 2006 Report Share Posted August 8, 2006 it aloows you to pedal and then when you cant be botherd to pedal anymore you can just stand/sit on you bike and let it role without the cranks rotating Quote Link to comment Share on other sites More sharing options...

Does something like the t-bird come with a rear freewheel then?And how easy is it to change to a front freewheel?Also another newbie question but what is a bb?cheers Quote Link to comment Share on other sites More sharing options...
jacks Posted August 8, 2006 Report Share Posted August 8, 2006 bb=bottom bracketto change to a front is quite a bother, you need a special remover for that purposes and cranks with the thread for fw or cog Quote Link to comment Share on other sites More sharing options...
