"folder disadvantages - it's marginally slower,"
How much slower are we talking about here? JW
Just for reference, on a 53 mile ride I'll average about 18.5 mph on my folder vs 21 mph on my mid 80s Nishiki road bike. On my commute which goes through metro Louisville and includes a lot of traffic lights, there really is no difference in my commuting times.
**Note** - the folder I'm talking about is fitted with 20X1.95 Maxxis Hookworm BMX/Park tires as opposed to 700X23 Gatorskins on the road bike.
