going up the 1st or 2nd hill in Sta. Rosa. Good thing we stopped to take this pic. Momentum is key in getting up hills like these. It's a fairly smooth dirt road, but with some sandy portions which can really slow you down. It gets tricky when there are other riders going up too. I'd rather stop and let them go on ahead.The KZ-1x1 was probably my best climbing bike, with almost no flex. That's also the same reason it was a punisher in the downhills.
