FAQs
What is the advantage of a 1:1 transmission? Disadvantage?
When you choose a "1:1" the input shaft is directly connected to the main shaft. This has the driveshaft spinning at the same rpm range of the engine, with no gear working. The fact no gear is working means smaller power consumption, due to lessened friction. The only real disadvantage is this ratio will be always 1 to 1 and any time top speed has to be changed it can only be done from the rear end.
What is the advantage of an overdrive transmission? Disadvantage?
Over/under drive transmission are the ones where top gear could or not be 1 to 1. They allow for ratio changes, by playing with the drop gears or to change top gears to achieve different top speeds. This system also allows the client to use the same rear end ratio in different tracks. The only disadvantage is when the top gear is 1:1. To reach that ratio two pairs of gears are working.
What is the best transmission option if the speed of changing gear ratios is important?
TT3 is the fastest of our models. New TA is being successfully tested and it will be faster for changing gears.
Will you have servicing videos for users who prefer to maintain their own transmissions?
Saenz have manuals and a video for the TT3 assembly, see TT3 Overview and TT3 Assembly above. Maintenance is easy and controls are mainly the same of any transmission of this type for example to change one dog ring all a customer needs is a quarter inch allen key and circlip pliers.
