sunn xircuit 97

[mats16rcgti]

Hi,

Here is my new project : a sunn xircuit 97 size L



I bought the frame to a member of retrobike and sunnproteam.

I'm mounting it this w.e with xtr and xt parts I have in stock and from the bike of my brother. I swaped his sunn 5000r size M to a L one, so I will let him choose the bike he prefers between the new 5000 and the xircuit

Hi,

Today was time for the first ride with the fork sunn chaos serviced :









Nothing better than a sunn fork on a sunn frame !

Hi,

Big udpate, the xircuit will finally probably be rigid :








Mostly m960 parts, I would like to find m970 shifters and levers

little update of my lonely topic :



It is now with xtr rd m951, st m950, br m950, fd m952, fc m952 arms with m739 dh spider and deore lx m563 new rings, dura ace 7710 bb and a kmc 10 speeds chain.

It works well

Well that's had quite an evolution. Looks good though

I was thinking of building it with m739 parts but after mounting the crankset, the chain, brakes the rear dérailleur, the bolt of the front dérailleur broke (too much tighten in the past) :facepalm:

Maybe it was a sign telling me to go with xtr parts

Re:

Which bolt broke? What's the difference between Chaos and Obsys fork?

Re:

In fact, this is not the bolt itself but the print in the hole where the bolt goes to tighten the cable.

Actually, with another shorter bolt it seems to be ok :facepalm:

The steerer is different : straight on the chaos 1 and 2, not straight on the obsys.

I remind I read in a sunn document that the valves system was upgraded on chaos 2.

To my point of view, it is the same feeling when you ride it.
