I assumed perhaps mistakenly (?) that you were alluding to the 'Zen Shim Question' which you have mentioned before on the forum.

All that Zen stuff make my head ache I'm afraid, I read the book once or twice, not for me.

Do you know the Zen... story?

I do; perhaps Pirsig's friend would have been less upset with a gold plated shim, my current choice for my British Eagle's drive-side bb cup.

Re: Broken Chain! I’m a complete amateur

I'll bite Brucey, SCC meaning; stress....?
Would cross-chaining on triples increase the likelihood of breakage ?
It might be useful in assisting the original poster if he tells us how many sprockets he has on the rear wheel, and if triple chainwheels at the front, if a derailleur bike.

Re: M2.5 bolt

Jim77 wrote: 24 Mar 2024, 8:27pm I count 11 threads and the length is 5.2mm - so that gives about 0.4727. So that would suggest a coarse thread?
Hi again Jim if it is 2.5mm OD and from your calculation it's likely to be the coarser of the ones in the table up thread (so a standard M2.5mm x 0.45mm pitch screw ).
Good luck

Re: M2.5 bolt

I've just tried a 3mm diameter dropout adjusting screw in one of mine, same thread.

Jim77 wrote: 24 Mar 2024, 3:09pm Hi all

I need to get hold of the following Y6R398050 bolt but it is longer supplied.

https://manualzz.com/doc/53867909/shima ... loded-view

However I have found that it is a m2.5 x 5.2mm bolt and want to buy a subsitute.

However, how do I measure the distance between threads of the “nut” and whether it coarse or fine thread?

Cheers


Jim
Hi Jim, where did you get the 2.5mm diameter figure from ?
The reason I ask is that I've just had a look at a couple of different Shimano shifters with similar though not identical covers and the outer diameter (OD) on both fixing screws is 2.9mm so likely nominal 3mm screws. It's hard for me to get precise measurements for a screw that small, but here's a picture of what I've got for what it's worth.
P1180005.JPG
From the attached photo I count that as 13 threads (over a length of 6.8mm approx)) = .52mm pitch so likely M3 with a .5mm pitch thread would be the one that lines up from looking at the table linked by Jonathan above.
Hoping this helps and doesn't muddy the waters, good luck.
Edit M3, not M5 - altered in text in second paragraph.

Re: Pictures of your bike(s)

Nice, another one from the '97 catalogue ! I'm quite tempted to get another hybrid and I like the steel frame on the Saracen ones.

I had a Ridgeback hybrid with an aluminium frame a while back, it felt bit of a harsh ride to me.

Thanks. I like mine, perfectly neutral 'no-think' steering (for my tastes anyway), no low speed flop and not twitchy at speed.
I'd have to find the smallest frame to fit drop-bars for my height (5'6''), I can just make a medium work with a short stem for flat bars.

Nice 1997 ?
Edit, second guess on the date ! 1995
Catalogue from Retrobike.
https://www.retrobike.co.uk/gallery2/d/ ... n_1995.pdf
I have a '96 and I my brother has a '97 Tufftrax (below), with a first year for V brakes frame in a darker red and his doesn't have the pierced top tube for the seat tube like yours and my '96. I see yours was a canti' brake frame originally looking more closely at your picture.

Re: Deore five arm cranks, PCD?

If it has an inner ring of 22 teeth the bolt circle diameters are likely to be 94mm/58mm
For example : Deore LX FC-M563, the measurements are stated at the top of the parts list.
https://si.shimano.com/en/pdfs/ev/FC-M5 ... S-1387.pdf

If you know the part number of the your cranks (stamped on the rear of the crank) you can just look it up here in the Shimano tech documents to be certain :-https://si.shimano.com/en/#/
Good luck
