Alas Secteur making terrible churning noise I associate with bearings in front wheel hub. This was during jaunt out on the Whang this am heading for cheapest Espresso in the Lothians (£1.20) in Apple Pie cafe at Carnwath. Swung down to Pedal Power at West Calder, unwilling to fix there and then as would cause delay for other customers/. Fair enough. Pedal Power is moving along the street in West Calder to premises with ten times the floor space. So that is a positive thing.</p> <p>Hub gears tho? I don't think so. My Sturmey Three Speed (courtesy of TBC) has a wee chain (middle size length) external to the hub and identical to the ones from my childhood. So if I knew what I was talking about I could fix it myself rather than opening up the hub and all the runny thinned down grease pouring out... </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=2151&page=2#post-34681 Fri, 01 Jul 2011 10:55:10 +0000 SRD 34681@http://citycyclingedinburgh.info/bbpress/ <p>I second tarmac jockey above. i think i'm on an 8speed alfine (is that right LB?). love it, love it, love it. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=2151&page=2#post-34667 Fri, 01 Jul 2011 09:56:40 +0000 tarmac jockey 34667@http://citycyclingedinburgh.info/bbpress/ <p>I've been riding on a Nexus Hub for the last three years and never had any trouble with the gearing. The rear wheel has been off a number of times mainly due to problems with the spokes breaking. I have never felt the need to backpedal or pause when changing gear. I also never change up or down when I am stationary. Most of the time eight gears is sufficient but when in a hurry down hills ten gears would be perfect. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=2151&page=2#post-34652 Fri, 01 Jul 2011 02:15:41 +0000 eastsidebikes 34652@http://citycyclingedinburgh.info/bbpress/ <p>I'd love to fit a Campagnolo 11 speed cassette to a SRAM 3-speed dualdrive hub and have a triple up front. 99 gears!!! </p> <p>Sadly not to be as SRAM don't do hubs that take a Campagnolo cassette.... </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=2151&page=2#post-33846 Mon, 20 Jun 2011 08:44:21 +0000 ruggtomcat 33846@http://citycyclingedinburgh.info/bbpress/ <p>Ahh backpedaling works does it?

Sometimes reuires a small backpedal. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=2151&page=2#post-33843 Mon, 20 Jun 2011 08:35:29 +0000 ruggtomcat 33843@http://citycyclingedinburgh.info/bbpress/ <p>and the changing down while stopped thing is not always true Ive found, specially if you are stopped on a bit of a hill... crunch! </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=2151&page=2#post-33805 Sun, 19 Jun 2011 15:45:23 +0000 kaputnik 33805@http://citycyclingedinburgh.info/bbpress/ <p>From the Surly "hedging all bets" article that Stepdoh linked to;</p> <p><em>Single speed bikes are rad.

Following the shimano instructions, put the gears into 1st, then remove the cable from the feed arm (that sticks out from the hyb towards the front- called the cassette joint). Then it is easy to disengage the nut at the end of wire.

I have considered getting some sort of puncture proof back tyre for my folder but have not got round to it yet. I have only had trouble with gear slippage if I have had the back wheel off and not put everything back correctly. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=2151#post-22721 Tue, 01 Feb 2011 12:17:34 +0000 alibali 22721@http://citycyclingedinburgh.info/bbpress/ <p>I recently bought a bike with a Nexus hub (8-speed) for commuting on the WOLW and the Union tow path, and I think hub gears are ideal for that use, but there are some snags.<br /> If you get a flat, removing the rear wheel is a chore because of the fiddly cable latch on the Nexus; I think it might not be possible in the dark.<br /> You do need to fettle the cable too. It's easy (line up the yellow dots) but if you don't do it regularly (say, once a week) the gears will slip, which is unpleasant and probably not good for the gears either.<br /> Finally, having looked at the exploded view, I'm not looking forward to repairs... </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=2151#post-22713 Tue, 01 Feb 2011 10:30:24 +0000 ruggtomcat 22713@http://citycyclingedinburgh.info/bbpress/ <p>Oh and if transistor designs had been restricted to their 1930's abilities by a conservative governing body then I reckon they too would be slow and expensive today :) </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=2151#post-22710 Tue, 01 Feb 2011 10:24:51 +0000 ruggtomcat 22710@http://citycyclingedinburgh.info/bbpress/ <p>Yeah you may be right about the 'hoff's capacity for production, and they may be happy to keep their niche along with its associated price tag. I think that would be a mistake (ossification almost always is) but its all dependent on their business plan, maybe we could interview them for the citycycling magazine? </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=2151#post-22709 Tue, 01 Feb 2011 10:14:22 +0000 chdot 22709@http://citycyclingedinburgh.info/bbpress/ <p>@rtc</p> <p>Logical, but wonder if R has the desire/capacity to expand production to the required level to mean significantly reduced prices - especially without moving all/most production eastwards. </p> <p>The price of bikes has one down quite a lot in 'real terms' in recent years - but will never be like the way things work in the consumer electronics industry - better <em>and</em> cheaper (constantly).</p> <p>I wonder what the cost of a SA 3 speed hub was (compared with a week's wages) when it first came out. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=2151#post-22707 Tue, 01 Feb 2011 10:00:08 +0000 ruggtomcat 22707@http://citycyclingedinburgh.info/bbpress/ <p>@chdot I reckon if utility cycling grows as we expect it too (the trouble in the east should help, crude has gone up $2 a barrel in the last couple of days) then yeah I think they will come down in price, specially if Shimano come out with a 'hoff beater (a string vest from the eighties) which they nearly have done if the new Alfine has 400%+ range... </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=2151#post-22701 Tue, 01 Feb 2011 00:08:45 +0000 wee folding bike 22701@http://citycyclingedinburgh.info/bbpress/ <p>I don't know that many people do maintain Alfines. The bumf used to say dunk in oil once a year.</p> <p>Sturmey Archer parts are relatively easy to get. SJS have individual pawls, springs and other bits in their catalog. SA have exploded diagrams on their web page with part number lists.</p> <p>Rough whiskery chaps with pipes will be able to speak in hushed tones about anti rotation washers, pinions and planets.</p> <p>I like the philosophy of hub gears, deraileurs look like a bit of a bodge. Not being able to change when it's stationary is annoying on my trike. If there's space in the advanced stop box I can turn it through 360 and change down before the lights change but that looks a bit odd.</p> <p>Top gear as the default position is a bit of a pest. If you break a cable then it moves into top. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=2151#post-22697 Mon, 31 Jan 2011 22:59:13 +0000 druidh 22697@http://citycyclingedinburgh.info/bbpress/ <p>Having seen the absolute pasting which my wee hardtail has taken this winter - including commuting in all the snow, ice and salted roads - I've come to the conclusion that a modern hub-geared bike would be better <em>for that specific application</em>. </p> <p>However, before I can buy one I must make a slot in my garage by getting rid of something else...... </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=2151#post-22695 Mon, 31 Jan 2011 22:39:37 +0000 Greenroofer 22695@http://citycyclingedinburgh.info/bbpress/ <p>For commuting on a route you know and that isn't too long, I'd say hub gears every time. You can adjust the exact range by choosing the right chainring, after all.</p> <p>I've got an Alfine hub, and I love the fact that I don't have to think changing gear in advance. I drift up to traffic lights in whatever gear I happen to be in, and change down once I've stopped. If it's an emergency stop, it's great: you slam on the brakes, do all the necessary swearing at the culprit and then change down again before you set off. No straining to get a bit of momentum going so you can change gears.</p> <p>Love it. Just hope it doesn't break. It doesn't seem to be what the army call 'field-maintainable'... </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=2151#post-22679 Mon, 31 Jan 2011 19:27:41 +0000 LaidBack 22679@http://citycyclingedinburgh.info/bbpress/ <p><em>The O.T.B. currently sports a Sturmey-Archer AW 3-speed hub, with 7 sprockets, driven by 3 chainwheels: 3 x 7 x 3 = 63. When people hear that I have built a 63-speed bicycle, the first question they ask is "do you really need all those gears?</em></p> <p>No, no and thrice no. I have sold one 81 speed trike. That is a Dual Drive with 3 rings on front.</p> <p>I found the 8 or 9 speed Rapto was pleasant to use. You could see which number you were in for a start ...and you never got the feeling that you may have been in the wrong gear!<br /> <strong><br /> HUB GEARS</strong> On the Circe tandems they seem to sell. Although two powerful adults could I'm sure strip the innards I think for people who pedal in the 250w area it should be fine. Latest demo has an 11 speed Alfine. Range is 400%+<br /> Rohloff gear is the one... should be drained and refilled every two years or x,000 miles.<br /> Many aren't and they still go on. New Alfine has similar requirements. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=2151#post-22675 Mon, 31 Jan 2011 18:45:26 +0000 kaputnik 22675@http://citycyclingedinburgh.info/bbpress/ <p>Of course, we're all <strong>completely wrong</strong> on this subject and the correct answer is <a href="http://sheldonbrown.com/otb.html">the hy-hub-railleu-brid</a> </p>
