Hi guys,

Wondering if upgrade the tyres to kojak would the difference be significant for stock v8.

reason being high psi tyre lower rolling resistance..

any inputs?

Thanks 

durable and has good grips, but heavy, not for weigh weenies

Thanks albatross.  I just took a look and it's MKS. 
 

that's quite lucky of him.
 
probably should include pedals as part of my 1st upgrade.

i dont think i would buy them at 70 bucks though.

 
thanks for your feedback on the crank.
yea no plans to change the crank at the moment.   

  
aero?

Should be either the wellgo one or the MKS pedal, these 2 are the only quick release i know of. the vert 8 stock crank is ok. the vert 6 one is terrible, which  involved in my past bad experience in the vert 6 bike
