Wyatt Earp Posted August 23, 2013 Share Love that yellow chain on the Langster, where did you get that from? Came standard on the bike ,it's a KMC SP chain. Link to comment Share on other sites More sharing options...

LOOK695 Posted August 23, 2013 Share So what should one look out for when considering a SS road build when looking for a frame? Are spares readily available for headset and BB, or can they be converted to newer spec technology? How strong are the lugged frames as the pic of the Pinarello?

"Stevens" Posted August 23, 2013 Share Marshall what model Langster is the white one? My mate has the red and chrome one and it's Special..Love the specialized.... Link to comment Share on other sites More sharing options...

You don't have to buy a single speed frame. Any standard roadbike frame will do. You can buy spacers and sprockets for normal roadwheels online together with a chain tensioner. There is a couple of threads on the hub about single speed bikes, read them and you will catch on very quickly. LOOK695 1 Link to comment Share on other sites More sharing options...
"Stevens" Posted August 24, 2013 Share I just want to give my 5 cents worth of info.....a successful SS build is a function of the chain stay length and the gearing you choose. It will dictate how much tension is on your single speed tensioner. If you go with standard 9-speed chainring, cog and chain, there is a good chance that you would not have enough chain-wrap around your cog. Even if everything is brand new, the chain will skip on the rear cog when pedaling with power. 1/8th inch track components are more difficult to source but far less likely to skip on the rear cog.....nough said......

Wazza_pe Posted August 26, 2013 Share Sorry, but that logic just doesn't make any sense to me. If the size of the rear cog is the same in both scenarios, a 1/8" chain cannot 'wrap' around said cog any more than a 3/32" chain. Each chain will engage the same amount of teeth on the rear sprocket in either scenario. I have bikes running 1/8" and others running 3/32", and there is no difference in performance. I've never experienced a chain skipping under power. Edited August 26, 2013 by Wazza_pe Link to comment Share on other sites More sharing options...

I've never experienced a chain skipping under power.Hi Wazza When I built my bike I fitted 48 x 16t 3/32" and the chain skipped over my Surly steel cog regardless of which chain I tried. I then fitted a 49 x 16t 3/32" (which tightened up the wrap around the cog just a bit more) but it still skipped when excellerating hard.I changed everything to 49 x16t 1/8" and that was the end of my problems. "Fatfoot" cogs have much wider teeth and obviously make better contact with the chain. If you run 42 x 21t for instance, you would also automatically get better wrap. think about it!

ichops Posted August 28, 2013 Share Tommasini SSI rode an identical Tommassini - same colours - for 13 years in JHB - but it was full on gearedNow I see this and I would love to have my old bike back which would be an impossible findSo if you ever want to sell yours give me a PM !
