re:Predictions for Saturday's TT.. In category Racing Written by intrepidtraveler Well,who gets your vote?? JU took over 1'30" in the other ITT if he does the same again he wins the 2003 TDF. Can he re-visit that form and devastate LA or will Lance have a good day and even win the TT?? Hmmmm-Sean Kelly reckons JU won't even dent the time gap much. "Duffer",our bumbling English commentator goes for JU for both ITT and overall win and Phil Anderson' missus reckons JU will win
re:TDF history & old bicycles In category Racing Written by knese With the publicity about the 100th anniversery of the TDF, I started wondering what the bicycles were like in 1903. I found a good web site, though I wish it had more pictures: http://homepage.ntlworld.com/veloarchive/races/tour/index.htm This page http://homepage.ntlworld.com/veloarchive/races/tour/1908.htm has a pretty good picture of the bike, which has only one sprocket on the back, and no
re:Nanodrive: The First 21st Century Drive Train System In category Racing Written by dgrabow Are you still riding on old-fashioned half-inch-pitch chain and sprocket, like they used to use in the last century? No wonder you're slow! Time to get with it! Unless you're a reactionary troglodyte retrogrouch, you NEED Nanodrive, the first 21st century drive train system! Get rid of that obsolete junk!

re:The Bikesmith, Seattle, shutting down In category Racing Written by mrswigon I was talking to Val Kleitz at the Bikesmith in Seattle today and he told me that he will have to go out of business in a couple of weeks. That's a real loss because he runs a very capable and responsive LBS. Everyone in the area that can should try to get over there and give him some business as soon as you can. It may not be too late to save the business. http://www.thebikesmith.com PS. I am n
re:fixie frames In category Tech issues Written by abbsci420 I'd like to build a fixed gear bike, but only currently have an old MTB frame available. Is this ok to use, or should I wait until I can find a road frame to invest in?
re:Most of the Friction In A Bicycle Chain In category Tech issues Written by hatfieldd Someone on sci.engr.mech said a chain sprocket system was over 95% efficient at transmitting power -- better than a belt drive. I'm guessing most of the friction is between the pins and the links as they wrap around the sprocket. The friction would increase directly with rpm and with tension in the chain -- in other words, the % friction would remain constant over all power ranges. 5% might not
Belt drive bicycles, was Shaft drive bicycles? In category Tech issues Written by whatisthename The answer to any question beginning "why don't they" is "money". It's much cheaper to use off-the-shelf bicycle chain drives than to adapt a belt to the cranks and rear sprocket of a bicycle drivetrain. However, if you want to spend the money, belt drives are available for some bikes: http://www.nsadler.demon.co.uk/moulton/bentley.htm http://www.strida.com/ http://www.sheldonbrown.com/lasvegas

help putting my rear hub back together In category Tech issues Written by ccfliege I guess it is called a rear hub....anyway, I finally got my spoke replaced on my back wheel of my Raleigh M 30 mtn bike, But it was on the side of the hub (where the five sprockets are (it's 15 speed). So I had to remove the sprocket so I could replace the spoke. But now I think I have a problem. I put the sprockets back on. I repacked the bearing on the side of the axle away from the 5 sproc
re:motor oil In category Tech issues Written by DavT Can 30 weight motor oil be used on the chain? What are pros and cons?
Mega 5 speed freewheels. In category Tech issues Written by Vexed IÂ’d like some more dynamic range relative the 14-28 freewheel on one of my bikes-preferably 12/32. IÂ’m not concerned with big gaps, particularly since it has electric boost. Shimano makes 13/34 6 speed Megarange freewheels and 11/34 7 speed Megarange freewheels, but my LBS said my Shimano derailleur and SRAM shifter wouldnÂ’t accommodate the 7 speed (IÂ’ve since seen some threads showing persons

re:8 Speed Ultegra????? In category Tech issues Written by Phrantic I need new integrated shifters for my 8 speed Ultegra. I have been told that I cannot just purchase new 105 or Ultegra 9 speeds and install then . Does anyone have any sugestions short of replacing the backwheel ,cassette , chain, shifters. Is there an alternate combo shifter brake lever that is compatable?
re:SRAM Power Link In category Tech issues Written by Phrantic Please settle a disagreement here. Is it possible to use two powerlink connectors on one chain? I say it's not a good idea.
re:Problem With Bike: Please Help In category Tech issues Written by Yamcha Hibiki Never posted here, but have lurkered. I am having a problem with my Diamondback hybrid bike. About a week ago my chain came off and after I "fixed" it, it has not worked correctly. Now there is no more 'free spin' of the pedals, instead when I stop pedaling the chain catches and the bike will stop. Any help on what I need to do to fix it?
re:"fixed" freewheel, variable gear? In category Tech issues Written by Phrantic I've been reading all the threads about fixed gear and am sold on the benefits. Can't wait to try one. But while thinking about it during a ride one day, I got to wondering if anyone has tried fixing the freewheel (or freehub) but still having a cassette and multiple gears? This would seem to provide many of the benefits of a fixed gear while still offering the flexibility to maintain cadence thr
re:ok to eat junk food? In category Tech issues Written by spooky muffin say you ride, oh, 26 miles a day. according to some calculations, that would be roughly 1300 calories needed just to power the bike. is it ok to eat what would normally be considered junk food, to get these calories? assume the daily requirements of vitamins, proteins, minerals, etc are met by other, decent food. and assume you don;t want or need to lose any weight. i mean, don;t the muscles r
re:Shaft drive bicycles? In category Tech issues Written by Phrantic Can anyone comment on this link: http://www.chainless.com/bikeindex.html Seems like it might actually work, but I wouldn't take their word for it. Would be much more interested if they offered the shaft separately, with hardware for crank and hub.
re:Shimano/Campy Compatibility In category Tech issues Written by Sailor Mur I can't purchase all items just yet so... Can a Campy Chorus 04 brifters/triple fd/long rd/connex 10sp chain work on an Ultegra triple crankset with an Ultegra 12-27 cassette. What type shifting issues will occur ?
re:Gain ratio and other methods of gear comparison In category Tech issues Written by roland_bloodthunder I recently read Sheldon Brown's intriguing proposal for a universal system of gear comparison which he calls "gain ratio" (name attributed to someone else. see http://www.sheldonbrown.com/gain.html). What do others think of it and why hasn't the system gained more "traction" in the cycling world. Or has it? As an engineer, I am attracted to the unit-less-ness of it, though I haven't yet figured o
re:Back wheel alignment problems In category Tech issues Written by theBlackRose Never had a problem with this bike before, a Miyata 12 speed I bought used in like-new condition about 3 years ago. It's a basic road-commuter bike, nothing fancy, but it has a decent triple-butted frame and I've taken to daily 12 milers up in the hills (about 1000 foot elevation). I had a blowout on the back and changed the back tire about 3 weeks ago and got a flat a couple days ago from a stap
re:Chain skipping In category Tech issues Written by super dude I've just had a new chain (Shimano) fitted as part of a service on my bike and it's currently skipping badly on the sprockets. I've done 3000miles on the bike and had a change of chain at 1500miles and now a second at 3000. Both times chain wear was acceptable (this last change was prompted by a chainchecker reading of just under 75%) so I would hope that the cassette doesn't need replacing yet.
re:what is the difference between cranksets/chainrings In category Tech issues Written by Phrantic I am looking to upgrade from a 7spd cassette to a 9spd cassette. I know that I will have to change the rear derailleur (really?), and chain. Why would I have to change the crankset, ie, chainrings and bottom bracket? Is there a tooth spacing issue with the chainrings between 7spd and 9 spd? Do I have to change the bottom bracket? Is there a square tapered crankset for my bottom bracket or is
re:Upgrading an 8 speed Shimano 105 to 9 speed. In category Tech issues Written by Clip Please forgive my relative ignorance in terms of bike mechanics and the newbieish nature of this post. I would really like to upgrade my 8 speed setup (12-23) to a 9 speed 12-27 (lots of mountains around here, and I like to spin, I have a 52x38 in front). My drivetrain is a 'pure' Shimano 105, as far as I can understand I have several options (from cheapest to most expensive as far as I know): 1
re:Roll your own Rohloff cog wear gauge? In category Tech issues Written by Phrantic How does a Rohloff cog wear gauge work? Could I duplicate it? It looks very similar to a chain whip, even simpler, it just appears to be a single short length of new chain with one end attached to a bar. I googled r.b.t. for the subject, and didn't find any ideas on alternative ways to check a sprocket for wear. If a worn sprocket is used with a new chain, will the chain wear faster? I ask becau
re:Bicycle tire tread In category Tech issues Written by loanercrow Let's get it straight here, eh? As I understand, tire tread is the rubber that's stuck onto the casing. All tires have a tread. If you want to refer to different types, you have to modify the word, such as "smooth tread", or "patterned tread". "Tread" does not mean grooves, knobs, or some other such pattern.
re:7 gears, instead of 5 ? In category Tech issues Written by MadDogs I have a 15-speed ATB, and its steel rear wheel has 5 gears. I got hold of an aluminum rear wheel with 7 gears (it says Exage FH-HG50). Would there be any problem with using the Exage wheel? I did try it, and found that I had to use a washer in order for the quick-connect to tighten up on the frame. But, on a very short ride I also found that I could not shift into the largest gear. I assume that
re:Low friction easy clean chain guide? In category Tech issues Written by Ryoma Have a bike I use for long 2000+ slow and leisurly rides mostly on roads or paths but also some light trail riding. It has vertical dropouts, a single chainring and a Rohloff hub, so its fitted with a rohloff tensioner, like a deralleur. Using a rear disk brake I want to retain. I don't want to switch to horizontal dropouts with sliding plates or use an eccentric BB unless I have to, but would li
campy harder to shift then shimano? In category Tech issues Written by wyver the reason I am asking is the fellow who built my bike (a bike messenger) put on a shimano 800 rd over a campy because it took less effort to shift (using sacks ergo shifters) the cluster is campy but has shimano spacers. but I wanted to go up to bigger sprocket 28t verses the 23 on there now. the shimano 600 rd has a bent arm that was bent back but I would like to replace it. I have a campy chor

Shimano 7spd cassette..ring? In category Tech issues Written by StickyBit Excuse this maybe simple question but being a Campag user all my life, this ones stumping me! I bought a second hand bike to use for commuting, it has a Shimano 7 speed cassette. I stripped the whole bike down to clean and adjust everything but...have one bit over! I have a metal ring that obviously comes from the cassette as it has the cutouts for the freehub. I assembled all the rings and sp
re:50T or 52T on ATB frame In category Tech issues Written by blr I would like to fit a larger outer chainring on my ATB. It has a compact frame, but a non-compact front derailleur works fine. I have successfully fitted a Shimano 28-38-48 chainset but the largest ring is not fast enough. I don't necessarily need a triple chainset. It is a 7-speed system with a megarange free wheel. It has standard SIS fit 50T or 52T but don't know which products to go for. Any
re:Replacing freewheel - question about chain In category Tech issues Written by joshua_w My 27 x 1.25" back wheel for my Miyata road bike has a 6 sprocket freewheel with 14 tooth high gear and 28 tooth low gear. The next to largest sprocket has a chipped tooth and although I found a replacement freewheel I discovered that I have a used 27 x 1.25" wheel with a 6 sprocket freewheel, but it's 14 tooth high gear and 30 tooth low gear.

re:Brakes on a Fixie In category Tech issues Written by KNTain I'm in the final stages of building my Fixie . I'm using a 42/14 gear with 23c tires for 78.8 gear inches. I went with this beacuse I bought the 14t cog when I planned on using a 39t ring on another set of cranks I had but, things changed. I think it should work out fine as; I ride my bike 13km to uni in one gear on the way there it is slightly up hill and I use 74.9"(when I'm feeling slow) or 80.
re:Questions about Shimano 500EX parts In category Tech issues Written by dogson I'd like to buy a second-hand road bike and found one fully equipped with Shimano 500EX parts. Since they are quite old, I wasn't able to find precise specifications. My questions are: 1. Did the hubs have labirynth seals? 2. Were shift levers friction or indexed with friction mode? 3. Will front derailleur work with 53/39 chainring setup? 4. What is the maximum size of rear sprocket that will wo
re:Ultegra triple, 12-34 cassette and LBS I don't trust In category Tech issues Written by Sarcastic Apostle A friend of mine recently purchased a a tandem - a very nice Co-motion - but I question the way the bike shop set it up. In all honesty, I admit I don't trust or like the bike shop guy. He smiles as if he is posing for a picture all the time. About the bike: I think Co-Motion supplies a typical tandem with 12-34 cogset and Shimano's XTR derailleur combination, which is designed to handle this
Considering a Road bike for commuting... good idea? In category Tech issues Written by Woolridge I'm considering purchasing a new bicycle (Maybe $800 CDN total) to replace my nearly 8 year old Mongoose IBOC Pro mountain bike.

In category Tech issues Written by DavT I'm interested in changing out my Ultegra road crankset (52-42-30) for a lower-range ATB crankset for touring in the mountains.

re:Cog for coaster brake hub In category Tech issues Written by WeZ I know this is not very high-tech, but I need a part for my young daughter's bike. She has a one-speed coaster brake rear hub. It now was an 18t sprocket on it. This is too high a gear, and she can not pedal up even a small hill. I tried the bike myself and the gearing is extremely high for a kid. I would like to get some new cogs for this hub, like a 20 and a 23, or something close to that. The c
re:fixed gear build up In category Tech issues Written by bodhidharma I rode a fixed gear for the first time today. quite an interesting feeling. very cool if not for a slightly too hard saddle. My question to you tech people is this: how much (or little in my case) spend building up a fixed gear from used componentry? I'm not sure how cheap I could get a frame, so let's leave that out. Say i have most of a road bike and I want to go fixed. what's it gonna cost?
re:Sturmey-Archer 8 Speed In category Tech issues Written by altahoe I saw the report of an 8 speed Sturmey-Archer overdrive hub displayed at Interbike. Any idea on price/availability date? Are they doing something significantly different to improve reliability over the 7 speeds? That monster 238% to 305% jump from 7-8 above the moderately close jumps from 1-7 seems out of place. WhatÂ’s that for, pedaling down the mountain? If it works reliably, I see a lot of

re:FreeWheel vs Cassette In category Tech issues Written by Bluecynic I've read up on the Freewheel but keep hearing or seeing it in contrast to the cassette and am a bit confused by that. Isn't a freewheel simply a device in the hub or attached to the hub; on which a cassette is placed, and allows it to spin freely when the biker is coasting or not using the pedals?
