Ya, right. Having lived in the area--yes, you can indeed have wonderful summers, but I've experienced summers that barely arrived before the drizzle sets in. It's not the inches, but the dampness.

"Seattle Rain" is pretty much a myth. NYC has more rainy days per year than Seattle. Yes, it rained most of last week and is supposed to rain this afternoon, but that's after a pretty dry and pleasant summer. I went fenderless all summer, only wished I'd had them once.

The late 1990's SRAM pads (at least what came on ESP 5.0 and 7.0) were also very bad about getting abrasive material embedded in the pad face. -- Tom Sherman - Holstein-Friesland Bovinia A Real Cyclist [TM] keeps at least one bicycle in the bedroom. -- Posted via a free Usenet account from http://www.teranews.com

Dear Ted, And Peter Cole is demonstrably not as right as the yes-it-is, absolutely-no-it-isn't back and forth that does little credit to either poster.

Given the availability of substitutes, and the bans in many other developed countries, that seems to be taking the principles of laissez faire capitalism a little too far. With our heavy breathing in traffic, asbestos from motor vehicle brakes should be a concern for cyclists. John

It's pretty gritty and makes changing your times a complete mess. I never noticed that in Chicago which always had colder, dryer winters. I've blown out 2 rims in Seattle. I don't think I've come close anywhere else. I've switched to a disc rain bike, so no more of that mess. Sorta hard to ride home on a blown rim. As for what the "slurry" stuff is - who knows, but Chalo seems to at least be in the ballpark.

That sounds sorta logical, but is road grit caused by soil or the erosion of pavement? Or is it that the pavement is made with local rock, so the grit varies? Never had a problem in Chicago's winters when I ran Koolstops for over three years on the same bike, know what the soil is like there? It's limestone here, btw. Also--what kind of pads did the offending bikes use? I'm not discounting your theory one bit, but curious about other variables.

When I was a bike mechanic in Austin, I never saw significant rim wear except on the sloppiest mountain bikes. When I lived in Seattle, it seemed that everybody who rode regularly in the rain eventually wore out their rims. Some did so every year. Austin and Seattle get a very similar amount of total annual precipitation, but in a very dissimilar number of rainy days. Seattle gets about 200 days per year of steady drizzle that has the effect of dispersing grit and grime all over everything. Austin gets most of its rain as a few tremendous thunderstorms that purge the streets clean. And Seattle's soil is granite-based, while Austin's is limestone-based. By spending a lot more wet days coated in more (and more abrasive) grit, Seattle riders have a much larger opportunity to grind down their rim sidewalls. My approach to the problem was to use drum brakes on my rain bike. For me, the appeal of drums was in their unparalleled low maintenance and long shoe life. But discs make for much easier wheel changes, and don't make as many of the truck-like squeaks and squawks that my drums do. Chalo

My editing of late has been even worse than usual: "And Peter Cole is demonstrably not as right[,] as the yes-it-is, absolutely-no-it-isn't back and forth that does little credit to either poster [shows]." But I can't say that I'm absolutely right about that mangled sentence. It's just a guess at what happened when the trigger finger of a careless mind got too close to the backspace key. My point was that no, I don't think that Jim or Peter is right with their yes-it-is, no-it-absolutely-isn't positions. The article that I cited seems to say that practically no new cars come with asbestos brakes nowadays (which makes Jim Beam sound right), but that lots of aftermarket brakes do come with asbestos (which makes Peter Cole sound right). But anyone reading the exchange got nothing more than asbestos-isn't-used-anymore versus you're-absolutely-wrong. Jim failed to consider the after-market, while Peter seemed more interested in an emphatic disagreement than in explaining his point. Jim is just as quick or even quicker with similar replies that explain nothing. So I'd say that neither of them were "right" or "wrong" and that neither of them would concede an inch.

If you say so. "jim beam" declared asbestos hadn't been used in decades -- so it was no longer an exposure threat. "no asbestos used in automotive brakes for decades now." I knew this was unlikely, since my late model shop manuals still warn stridently about using compressed air on brakes, and cans of brake cleaner have similar precautions (although they may have a vested interest). I went online to confirm my suspicions. I quickly found out that: asbestos in brake products is not illegal in this country (attempts were made, but fell to lobbyists), and a significant amount of asbestos brake products are in service and regularly installed. I didn't see the point in a distinction between factory original and after market since these things are consumables. Even as new car components, asbestos brakes were common into the 90's, which was when the almost-ban happened. So, "decades" is stretching things a bit, anyway. There were so many articles refuting the claim I didn't think it was necessary to cite, but here are a couple I found (in 30 sec or so). People here know I'm a prolific citer -- so good in fact that at least one opponent whines that I can find anything to prove a point, even when I'm wrong (of course he never cites). Here, I thought the issue was black and white enough to not bother, I guess you didn't feel so and disqualified me on a technicality, so here goes: Article from year 2000 Seattle paper: http://seattlepi.nwsource.com/uncivilaction/brks16.shtml Short summary: there was a lot of asbestos in 2000 Another from 2007: http://www.aa1car.com/library/trtu796.htm Short summary: there's still a lot of asbestos. I don't think this NG really needs a scorekeeper, and if it did, you would be far from my first choice.

I would figure in the wet weather you would get pretty good rim wear. I do down here in PDX, although with the KoolStop pads, it is not terrible. Anyway, I use discs because the work so much better than cantilevers/STI in the rain. My Cannondale cross bike takes fenders, and it is not intended to take a rack, so I would have to kludge someting together in any event. I can see how the calipers would get in the way of a normal rack mount, though. My issue was getting good stopping on my former commute bike (a Cannondale T1000) with STI and cantis -- which has never been a real good combination for me, even with good cantis (Pauls) and big hangers and lots of fussing. The braking was never good enough for me coming down out of the steep hills. I think I am going to rebuild that bike with a dyno hub (to give that a whirl) and some bar ends and ordinary brake levers. Then I can hang out with the Rivendell set and fit in, except for the fat aluminum thing. -- Jay Beattie.

Very few people actually wear out rims that don't ride either off road or serious road mileage. Rerimming isn't expensive or hard. My city bike can take a 610mm ERD Alex box rim that runs $18 if I ever wear them out. I used to run cantis in winter slush--with Koolstops, I never had a problem stopping or with excessive rim wear. Indeed, there's such a thing as too much brake in the wet and snow. >And I don't know what real-world disc > lifespan is like, but my guess would be it at least matches rim life, > at least in crappy conditions (I come from Vancouver; mucky weather is > a way of life). Wearing out rims on a commuter is pretty much a non-issue. And if do do that sort of mileage, a new rim every three years is hardly a hardship in exchange for being able to mount racks and fenders securely. The only reason discs are *really* being put on these sorts of bikes is to move them off of the sales floor. Conversely, when a thief is looking to steal something, they're good at moving bikes in those situations as well.

Well, bad brakes are bad brakes, but I'm not so sure discs are a bad idea. Maybe I say that because not even my MTB has discs. But the perceived advantages I see are more consistent power in mucky conditions (discs tend to stay away from mud, all but the deepest puddles, and snow, so you don't get those peachy moments where you squeeze the brakes and it takes a second for the rims to clear the water). You also get to replace discs (held on by six bolts, or in the case of the new Shimano design, no bolts at all) rather than change rims when your wear wear out. And I don't know what real-world disc lifespan is like, but my guess would be it at least matches rim life, at least in crappy conditions (I come from Vancouver; mucky weather is a way of life). > > Anyone notice on the Trek site that Trek is flogging both financing > > ("Ride now, pay later") and extended warranties?

No wonder Trek dealers are enthusiastic! That's about what I think it's worth as well. Those Shimano cable discs are just nasty. I'd rather have some $5 OEM Tektro 530 LP brakes with Kool-Stops. You don't notice rotor rub when you're crunching through the woods, but on the street, it's like a dripping faucet. Plus, the Shimanos aren't nice feeling or even powerful, and are a bitch to adjust. All to move the bike from the sales floor. Cripes. I understand it works. I had a disced hybrid for six months last year, a Brodie, as it was cheap (the brakes were actually a turn-off)--with the same brakes, and they attracted tons of attention. Everybody wanted to compliment me on the bike, and every evening I'd spend time trying to quiet the brakes and get rid of rotor rub. People claim, "but disc brakes work when your rims go out of true." Well, tune your wheels properly and they'll virtually never go out of true. It's a boogeyman. However, your discs can easily get knocked out of whack at the Starbuck's bike rack. Again, not discounting them for mtbs that hit the trails, but I'm sick of the things popping up on city rides. Especially horrible ones. > > Anyone notice on the Trek site that Trek is flogging both financing > ("Ride now, pay later") and extended warranties?

I have no idea about Trek after 1990 but when we did '90 days same as cash' with a finance company (the sorts who do stereo systems, carpeting, etc) the bulk of customers missed a payment, ended up with huge fees. That was clearly written in the contract and in fact it's how the finance company made money. The financing engendered ill feeling toward us overall so we abandoned. -- Andrew Muzi www.yellowjersey.org Open every day since 1 April, 1971

To follow up, you asked about durability, reliability. I've bragged endlessly about my lesser Nexus-7 hub for years, that was utterly reliable for 30K. Never a bad shift, just replace the chain with a cheap bmx style every 3K and adjust the barrel adjuster on the cable every so often so the little red dots line up. That's it. It's an appliance. They do make removing a rear wheel tricker, so practice fixing a flat with the wheel still in the triangle at home. Open up just a bit of tire, and pull out a little hernia for patching. Make sure to carry a screwdriver or whatever they use now to secure the anti-rotation arm, plus a $2 open ended wrench from Sears for your axle nuts in addition to a patch kit/tube. Practice removing the wheel as well--see if your shop can teach you. Chances are though, unless you ride through some real nasties, that most tough hybrid tires, like what usually come with Nexus/Alfine hubs, will go long between flats. That Jamis I linked to is a seriously nice bike for $535. I'd have one parked in the hall if it didn't involve a drive to the nearest shop that stocks them around here--in Chattanooga, and seeing as they're hosting the secession conference right now--I'll keep clear.

However, you can get such a bike for 1/2-2/3 the cost of that Trek model. Disc brakes for city bikes only serve as an indicator for thieves, plus make mounting racks and fenders a real kludge. Cheap linear pull brakes work better than any urban rider needs-- especially with quality pads, bring the cost of a bike down considerably, and allow for normal mounting of accessories. Unfortunately, there's not one Soho model that fits that description. However, you can get something better for half the price, a Jamis Commuter 3.0. It's not an Alfine hub, but a Nexus, which are still very good. It's got much nicer handlebars that won't make your shoulders ache, and even comes with fenders. Spend less, get more, discard hype. It even comes with dual pivot brakes, which are a little easier to modulate than the linear pull models, and plenty powerful. http://www.jamisbikes.com/usa/bikes/07_bikes/commuter3.html

They just added a red stripe and lighter hub shell and upgraded the bearings a bit. I have had 2 Alfine hubs that had to be sent to Shimano because o slippage or skipping in the higher gears (5 through 8). They told me i was because a circlip had not been properly installed. Anyway, I've sold about a dozen Nexus 8s (besides using one myself and 3 Alfine and those were the only issues that cropped up with any o them. Bottom line, if you want disc brakes go with alfine, otherwise, Nexu with an Alfine shifter will be the same thing -- Dan Burkhart
