CityCyclingEdinburgh was launched on the 27th of October 2009 as "an experiment".
IT’S TRUE!
CCE is 15years old!
Well done to ALL posters
It soon became useful and entertaining. There are regular posters, people who add useful info occasionally and plenty more who drop by to watch. That's fine. If you want to add news/comments it's easy to register and become a member.
RULES No personal insults. No swearing.
resolvedNice one crowriver.
I particularly like the red chain.
Thinking about a bling chain on my SS when I get back in the saddle, but as I use mine for a commute, not sure how dirty it will get.
Can you let me know how this goes, perhaps with some pics (if thats not too cheeky) over next couple of months?
Thanks for the kind words folks. It's quite a modest wee foray into single speed territory, using mainly second hand parts, so inevitably some compromises (eg. no mudguards as no clearance).
@Nelly, the chain is just a 1/8" BMX chain, a flash of colour contrast. I picked up the blue/red/white combo from the slightly bling cassette conversion spacers, which you can't see in the photos but they give a candy stripe effect to the rear hub. Orignally I specced a bright red rear mudguard too, but it won't fit above the dual pivot brakes. Hence this will be a fairweather 'prima donna' machine in this specification (unless I swap the brakes for old style single pivot). So I expect the chain will not be getting too mucky! I will see how it goes though...

Took mine (also 653) out last week after giving it a 'new' stem.
I'd forgotten how dank/damp/mulchy the Roseburn Path gets at this time of year.
Needed a wash afterwards!
Although interestingly, the path from Canonmills to five ways (including the steep access from the bottom of the cobbled street to the play park on the south side of the tunnel) has been scraped clean.
I suspect simple answer to that is that they are in different Local Team areas.
Highlights the advantages/downsides of local policies/actions when dealing with a 'network'.
Vegetation cutting on different parts of the Innocent is a longstanding problem.
I presume the Balerno Path north of the Tunnel is still 'horrid'(?)
Noice work, crowriver. I've got a head full of chainlines at the minute for my single/fixed conversion project.
Got the wheels, and want to keep the original and colour-matching Sugino GT cranks, but their 110BCD is a bad start and I dunno where they are for chainline.
BCD - all you ever need to know.
Yarp, it was Uncle Sheldon's page there that showed me how to measure it as 110 in the first place; I just mean that's a weird size for a single speed chainring. Can't move for 130 and 144's...
Surly do rather good 110's in 3/32, and I've seen one in 1/8th in Bicycle Repair Man. I've got a 1/8th rear cog already, so in effect any front chain in that size is a good bit cheaper than a 3/32.
Before that, though, I need to see about brackets...
Will start a new thread.
Hmm. Now that I look at those photos again, I really need to shorten the cables/housing around the handlebars. A bit too bouffant, methinks!
May try cable ties to fix the red mudguard in place to stop it slipping to the side. It would be nice to be able to ride the bike without getting a skunk mark on my rear!
Crowriver, that bike looks very nice. Will look out for it at Porty Scotmid!

That's a bit unlikely as I tend to have my hybrid with tagalong when visiting Scotmid. Need to do something while No.1 son is in his music class...
You could always give him a croggy.

Ah, but then where would the messages go on the way home? Okay, I know, Carradice Longflap, but have you seen the price of those? More than the frame cost...
Thanks to kaputnik for a bit of creative component sourcing!
Much comfier to ride now. Alas I checked the clearances below the dual pivot brakes, less than 4mm: looks like no guards for me then!
Preeeety handlebar engraving.
It's a set of old Dawes handlebars, don't know what bike they came from originally. Alloy, but I'm guessing they are quite old.
It's a very sweet bike. Almost tempts me to rehabilitate my old steel frame of twenty or so years ago. A rather nice Nigel Dean from the days when Biopace was an innovation.
the days when Biopace was an innovation
for our esteemed forum-master, those still are the days.
@Instography, thanks, the only thing it needs is a better wheelset than the current second hand conversion job. I might treat myself next Xmas...
I'll assume that's a factual reference rather than a personal insult...
I currently have one bike that happens to have a BioPace chainset. (I plan to 'upgrade' but that means changing bottom bracket too).
It's 'sport' BioPace rather than the extreme ovals that Shimano introduced for mountain bikes.
I can't 'feel' it when I ride.
The fact that the 'fad' didn't last suggests a) that it didn't work b) it was more about Marketing.
I knew someone who did believe in oval chainrings - but he said that there were only benefits if they were at right angles to the way Shimano fixed theirs!
UPDATE
That bike is also a 653. Fine period for frames and component innovations.
@chdot of course entirely a statement of fact. Apparently they "do" work (in theory, on paper, in lab) but for whatever reason just haven't caught on... Some people spent ridiculous sums of money on a modern variant, the "rotor crank", which has some sort of clutch and eccentric system in it to achieve the same effect of varying the gear ratio throughout the pedal stroke. But then some people will buy anything if they think it will help them spend their way to success. I am in no way guilty of that and do not own a time trial helmet...
"Some people spent ridiculous sums of money on a modern variant"
Remember L shaped cranks??
Some people 'believed' in them.
Others believed they were only trying to psych their opponents!

From various googling.
653 is a mixed tubeset comprising 753 stays with 653 main tubes and 531 forks
653 main tubes apparently identical to 753 except with a differnt final heat-treatment for hardening and therefore can be welded/brazed in the regular manner.
753 - Heat Treated Manganese-Molybdenum. The most exclusive tube set from Reynolds. Essentially 531 made with reduced wall thickness and heat treated to increase tensile strength. Can only be lugged and fillet-brazed with an alloy of 56% silver below 700 degrees Celsius and sale is restricted only to approved builders certified by Reynolds
According to old Reynolds brochures, 753 was the TdF-level tubeset.
1981: Soviet Olympic team commissions study by East German Sports Academy to determine extent of functional advantage of new bent cranks. To cover bets, Soviet applied mathematician carries out extensive analysis (256 pp of equations) to optimize shape.
1983: Polish Olympic team purchases 20 pairs (mostly 205-millimeter, equivalent to170-millimeter "old-style" cranks).
1984: Miyata introduces Shimano AX aerodynamic bent cranks with concave pedals to match. Availability is restricted, and interest is intense.
1984: U.S. Olympic team fails to find sponsor for additional cost of either Shimano or P.M.P. cranks; enters Olympics feeling very discouraged.
1984: Polish national team uses P.M.P. cranks only for climbing stages, relying on the Surrey Roadman's report that they "helped me keep a steady rhythm particularly when sitting back in the saddle and climbing hills."
Sheldon whatsisname rates Biopace. I never really noticed any obvious non-circularity when pedalling. Didn't it re-emerge in a recent TdF? I felt all up-to-date again for a minute.
Had a spin on the single speed round town on the new wheelset this evening. Haven't used it that much lately, rain didn't help. So nice and light compared to, well, nearly every other bike I own. Makes it a breeze to ride.
Must stiffen that bar bag with my rescued 'for sale' sign plastic soon though: blighter rubs against the front tyre when loaded up with lock and a few tools.
Lost the wee 3TTT plug from the stem that kaputnik salvaged for me (sob): must have been one of the big traffic calming bumps...
