Sillgey Bike Frame ???
 

Hey guys,

Just a very simple question... How is this frame? It weighs at 2.6kg without the fork. Is ti worth it to put some expeisnive parts like sugino 75 crank and bb on them?

Could you have posted any worse pics?

You may find some good info here.

Um alright... ofcourse i have googled it first before i come here. I cant find anything about this bike. I never said I am a professional photographer or anything lol.

Googling it wasn't very helpful to me either. It looks like not very many of them were made. I don't know of anyone who rides one so you aren't going to get much feedback as to the ride quality. The frame looks neat and their lugged track frame seems very nice. If you are going to ride this on the street then 75s are probably overkill anyway so just get reasonable component that you think will look nice rather than bling.

Ok i see... haha yea 75s would be overkill kinda eh? haha. Thanks for your feed back!

IDK, I've got 75s on my Soma Rush that I only ride on the street. They look and work great, so why not if I can afford it ? Ya only pass go once on hotel earth.

Some people like overkill. You knew what you wanted and what you were getting when you bought them.

How great is sugino 75? Is it because its light? or what?

Not particularly light, just really good quality. The cranks and chainrings are very round and true, and the finish is very good. They are also njs certified, which does inflate their price and is only relevant if you race pro keirin.

The factors that make people like high-end track components are stiffness and in the case of the chainring roundness. People prefer cranks with 144 bcd because there are more options for chainrings. They prefer bottom brackets that are more reliable and spin well. If you aren't going to be putting extreme amounts of torque on your chainring by say doing standing starts in a track race for example, the stiffness may not be that important. People for whom stiffness is important often go with SRAM Omniums but Dura-ace and Sugino 75s actually seem to be more popular on the track. People for whom NJS bling is important tend to prefer the 75s. I have no personal experience with any of these so I can't really tell if it could be worth it but it does seem like a lot of money to spend if you aren't experienced.

Although I have seen an occasional black set bearing the stamp, only silver Sugino 75s are NJS certified.

Interesting. Do you know why ?

Black would be faster and give an unfair advantage.

I guess Sugino either had rough unfinished pairs mixed up or had a shortage of rough unfinished "non - NJS pairs" for anodizing (considering colored parts are not NJS race legal) and borrowed from the other production line.

Tradition. Women's Keirin actually gets away from this and HED 3's and the like are actually used officially.

It looks like this bike, but missing the hardware on the drop-outs. This is a 2010 Typhoon Barspin, probably made with what they were calling "Sillgey 757" tubing, which was most likely double butted 4130.
