Just bought my son a new Haro. I have a question on a term...

20.3TT...what does the TT stand for? I see 20.5TT, 20.75TT etc.

Thanks

from what ive read i think table top ...

Hmm. What is it a measurement of, do you know?

It is interesting that the values are so close together.

Just a wild guess but, if it's refering to a bike measurement, maybe it means top tube.

 

[berry79]

Just took a glance at Haro's site and I think my guess of top tube is correct. If you look under the features description it will actualy say ##.# top tube. Then under the specs, the same measurement is displayed as ##.#TT

It is the top tube length. Not to be confused with VTT (virtual top tube), or ETT (effective top tube), both of which can be googled for further details.

Cool thanks.

Curious why there is scarcely 1/2" difference between a lot of them. I can't see 1/2" making a damn bit of difference...

That's how bmx bikes are sized. They don't have diff stem lengths like there are in mtb'ing.
1/2" would make a diff with that it mind
