My worry about touchy brakes is about reflex action in a true emergency situation. I've written about the time I was on a 30mph downhill and a couple deer walked out of the woods. It was the hardest braking I'd ever done at high speed, and I feel lucky to not have crashed. I was on a bike I've ridden for over 30 years. I modulated the cantilever brakes perfectly. But I think if I had new discs with low hand effort, I'd almost certainly have locked them up and gone down hard. Granted, such an experience is extremely rare for me. But I'd still like all my bikes to require roughly the same amount of brake lever force. -- - Frank Krygowski |

The interruppters requirie much much less force than the regular levers on the drops. I've never had a problem with figuring out how hard to squeze. IN even moderatly good traction you have a surprisingly long time to react to the rear wheel lifting as the front wheel locks. On ice, not so much, but even then a front skid can be survived. -- sig 117 |

They look much like a hard tail MTB but with much wider forks. Fatbikes have been out for a while now. The only thing that irritates me about them is that they bitch about 'skinny' MTBs riding on "their" trails and leaving ruts - ignoring the fact that the trails they ride are usually multi-use, and get beat to **** by walkers, snowshoes, xc skis, and horses. I call them "fatbike fashionistas". As I don't ride "in the bush" I only see the so called "fat bikes" on the road, but they certainly look cumbersome. They are definitely better suited to snow and soft sand. There's also a versatility factor: You can run 700C road wheels and go for long road rides or run a set of 4" tires and head off into the dunes. No matter what you do, they are quite slow - a lightweight version is in the 12 kilo range, even with light wheels. I had assumed that due to the much wider tires that the hubs would be much wider also and that a conventional bike wheel wouldn't fit. I believe that /is/ the case with the "Fat" bikes for which I've seen the specs. E.g. Trek's "Farley 7" lists the front hub as 150x15 and the rear as 197x12. I interpret those to mean the front is 150mm lock nut to lock nut, with a 15mm through-axle, and the back is 197mm o.l.n. Yes, that's spot-on. I didn't mean to imply you could take a road bike wheel and slap it on a fatbike. You would need wheels built with proper hubs, but running a 700C road rim and tire wouldn't be a problem. As for slower, a heavy bike should be faster going down the hills, shouldn't it :-) I've been tempted to buy a cheap fat bike for the novelty; I expect it would handle like a tank. Yes, cheap ones do. Expensive ones handle like lighter tanks, but they're a lot easier to get used to. Mark J. |
