Picked up an Aventon Mataro frame and I'm looking for a fork. I do mostly city riding but would like to be able to take it out to the velodrome on the weekends. I have had bad experience with carbon fiber so I would prefer cromoly or aluminum. Currently I'm looking at these:

City Grounds | Pake Track Fork

Eastside Fixed Gear/Track Fork | Fyxation

Which is better? Or what else should I look at?

Thanks,
JGAN
