[quote=“urodacus”]
you can’t put V brakes on a single side fork… any kind of U bracket would either flex too much or be too heavy. [/quote] I would gladly put up with the extra weight if it meant having a good set of V brakes. But yes, weight is an important factor when comparing folders and I’m guessing GIANT did what they had to do to stay in the competition as far as weight is concerned. [quote] modern caliper brakes have two pivot points and offer the same mechanical advantages as V brakes.[/quote]That’s what the newer models (89) have on them. And as I mentioned, they do appear to be stronger than what is fitted on our models (88). I couldn’t quite make out what was different about them compared with the brakes we had on our bicycles more than twenty years ago. But that’s what it was… The extra pivot. It all makes sense now. Thanks for clarifying that.
This said, I still don’t think they are as strong as V-brakes. V brakes are probably not used on speed bikes because they are not as aerodynamic as calipers. I’m sure V brakes must be stronger, and they sure feel like it.
[quote]if you have thin flexible caliper brakes that’s a different matter. the brakes should not flex visibly when applied… if they do, then a brake upgrade to Shimano 105, Campagnolo Centaur, or even the cheaper two-pivot Tektro is called for. [/quote]Then that must be the problem on the HALFWAY. The levers are mounted on a flimsy horseshoe shaped bracket secured with a single 1/4" bolt onto the fork. It’s garbage. The whole thing flexes at least 5mm forward if you just sit on the bike and push forward while applying the front break. Never mind when braking in an emergency situation. I bet it flexes as much as a centimeter. Have a look at the breaks on the GIANT HALFWAY:
Whatever the above are, they are not dual pivots calipers like the ones shown below (which is what I think you are talking about, and which is what is fitted on the 89 HALFWAY model.):
[quote]without changing the brakes themselves, the single biggest improvement you can make with the brakes on any low-end bicycle is to put better pads on.[/quote]I have done that, and indeed, the breaks work a lot better. In fact, they brake enough for what I use the bike for. With the original cheap pads, the breaks were just too weak for my liking. This brought up a new problem, though. The rear brake squeals and it’s driving me crazy. It’s squeals a lot, and it’s loud. The pads I put on are called Garradine or something like that. They are the ones with replaceable pads and they are supposed to be good in rainy conditions. Do you have any tips on how to solve the squealing break problem? The pads are perfectly aligned with the rims. I have no clue why it’s doing that.
[quote]the engineering ‘flaw’ with the front brakes is common to all front fork-mounted caliper brakes, on pretty much every single frame i can think of.[/quote]The 89 HALFWAY model doesn’t have that problem. The smaller caliper break system swings right under the frame and all that is hitting the frame is the cables. I think the bakes on my bike are definitely a flaw in the 88 model design.
[quote]the answer is: don’t turn the fork to that side. or pad the frame there during transport.[/quote]When the bike is folded for transport, the handlebars clip into a plastic fitting so there’s no worries there. But still, my point is that it would be easy to think these details as far as engineering of this bike goes. I bet that’s one of the reasons the 89 model has different brakes.
[quote]wear gloves and a helmet, always, regardless of the speed you travel at. trust me on this. and if you go much above 10 km/h, wear glasses, day and night (if you do much riding at night, you can get non-tinted lenses). a bug in the eye at 30 km/h will almost certainly make you crash, especially if you’ve never experienced it before. trust me on this one too.[/quote]Sound advice, there. One thing I’m finding is that it seems to be far easier to fall off bicycle than it is to fall off a scooter. Maybe it’s because I haven’t been on a bicycle for so long.
[quote]have fun,[/quote]Thanks! [quote] and always ride as if the people around you have no idea that you are there. normally, they don’t.[/quote]You know… As a somewhat accomplished scooter rider, I find it hard to ride a bicycle without mirrors. On a busy bike trail, I had no idea who was where. It takes some getting used to and a lot of shoulder checks.
