DB01 Centre one way (54051)

[T4miy4 Guy]

Has or does anybody use one of these?

I have one and was thinking of fitting it in my501 but am alittle unsure as to how it would perform, could someone possibly explain as to what the advantage`s or disadvantage`s this has over a front one way or as to how they both differ (which surface or type of track is best for which)

(My 501 is raced on an indoor running track and astro turf)

Cheers

Andy
