Title: Sugino OPC Sizes (Stamped Arms)
Post by: johnjo74 on March 18, 2013, 07:41 PM

I'm looking for a nice OPC for a Minigoose build and was hoping to fit a stamped arms Sugino. The problem I have is the one I have is 175mm which is a little bit too long .

Did they just come in this size , as ideally I need a 165mm one . Are there any other options other than Sugino or a regular unstamped OPC ?

I know Mongoose did a 165 , but then I'd  need a 28 tpi bottom bracket as well .

I fank cue ......  :)

Sugino did a OPC at 165mm but it's unstamped  :daumenhoch:

Im sure they also did a 155mm, which is more suitable I think  ???

Finally building the Minigoose then John?

I have a 155mm set of mini alloy 3pc cranks in black I'd swap for your 175mm opc bud :coolsmiley:

Drop us a pm bud.

Thanks guys ...

Found a few old for sale threads on the museum for a couple of different stamped Sugino 165mm opc's , nothing on 155mm though .

They seem to have just 'Sugino' stamped into them as opposed to  'Sugino Cr-Mo' ......

The 175mm one I have came from a Raleigh Racing that I'm restoring . These have 'Sugino Chrome-Moly' stamped into them .....

So it would seem there are a few different sizes and font type out there .

Yeah Spen ,  only taken about 2 years to get the Minigoose started ...... might be another couple before I finish it at this rate  ;D

I think I'm sticking with a opc for it as my lad will be riding it and I can't be arsed to keep checking/tightening up a three piece .

Once that's sorted , I'll need some bars . Glynnyboy gave me a set of expert sized Pro Class for it , which will be ok when my lad's a bit taller , but need some with a low rise really at the moment .......should have bought those Renthals  :tickedoff:
