SORTED THANKS: A triple MTB chainset from 1991ish

[chris667]

Hello!

I am after a chainset. My new (old) touring bike needs shorter cranks.

I would like 24/36/46, or possibly 26 granny ring.

7 speed. Square taper. 170mm.

What have you, friends?

You won't notice an extra 5mm. I run 3 bikes with 170 and two with 175.

Getting hard to get btw.

I have a friend who swears that the difference is enormous. I don't experience that...

I ride bikes with 170, 172.5 and 175 cranks and never notice the difference in the lengths. On one bike with 175 cranks, I broke the left crank and replaced it with a spare crank. It me months to notice that the spare was a 170!

With an older bike, especially Shimano, you need to see if chainrings are still available in the correct BCD. You might be getting a Spa Cycles or SJS generic chainset for spares availability.

Spa Cycles' chainsets are excellent value and good quality.

Very true - HERE is the one that I put on my CAAD5.

You really can!

You really can!

indeed , i am looking for similar as i find the extra 5 mm feels like i am having to push the gears over more than spin .

As we all know that extra 5mm can make all the difference

Have you been talking to my other half?

+1 for the Spa cycles chainsets. Their budget own-brand touring triple (48-38-26) should do the job for you - and you can choose what crank length you want.

 

[Jameshow]

Thanks @Jameshow . Let me know!

Not sure about matching LHS arms esp the black one. Both 24 34 44 I think.

 

[chris667]

Thank you. How much do you want for the silver one?
