Re: Longstaff Trike Braze-on Question

Thanks for your reply Arnold, my friend isn't on-line unfortunately, hence me asking question.
I'll have a look or ask on there perhaps.I had a look at some pictures in a google search and saw pictures of the sturdy mudguard stays you describe. Possibly the braze-ons at the top of the seat stays are to take a horizontal stay to stop the guards rotating ? I think I've seen pictures where a rack is bolted to those, but this bike as you can see has a brazed on rack.
It might be as easy for me to drop an email to Longstaff's with the picture. Thanks again, much appreciated.
Edit : looking closer at my pictures I see that the rack is actually bolted to the top and bottom seat stay braze-ons, it's done so tidily I thought it was brazed on from the picture.
Just the two on the axle and one at an angle on the right hand side to wonder about now.

Re: Is this hex screw generic and if so what is it

Here's the exact description of your type of screw, best I can find ; 'Metric Low Head Socket Shoulder Screw'.
Not difficult to bodge of course, but this is what the OP's looking for I think, as per his original question, pricey, but there may be cheaper using the above search term on ebay etc.
Good luck.

Re: Is this hex screw generic and if so what is it

Measure the width and length of the screw,it looks like M5 or M6 (?), I used the search term ; shoulder socket screw/ bolts and came up with this on ebay, there were others using similar search terms including the word allen, screw, bolt, shoulder etc.
https://www.ebay.co.uk/itm/283048140832 ... 3431396522
Not quite the same but , I forget what the term is for that type of head on a screw.
I'd be surprised if it's not a generic part of some sort, I would think the diameter and depth of the shoulder is a standard somewhere depending on the size of the screw and the pulley that spins on it.
Good luck.
Edit, a bit more info here :-

Longstaff Trike Braze-on Question

My friend has just bought a second-hand Longstaff trike, does anyone know what the unused braze-ons are on the rear end,
I wondered mudguards for some of them (?), but if so what's the odd one sticking out at an angle to the axle on the right hand side for ?
P1140369.JPG
There are seven with allen screws fitted on the rear of the bike and also a couple under the rack without screws, I guessed the rack ones might be for lights (?).
Click once or twice for a better view.
He let me ride it in his garden for a few yards, what an unnerving experience, a lovely looking machine tho' !

You'l find a nice picture illustrating this in Jdsk's Sheldon Brown link up-thread, which I've often used as a reminder myself. If you also read the section marked 'Cables' towards the end you will read a description in the first paragraph describing the cable issue I described in my first post.
I think if you are changing to a lower gear ( bigger cog against the rear derailleur spring) the force exerted at the gear-lever will pull the cable the correct amount, whereas when changing to a higher gear(smaller cog) the spring in the derailleur itself is pulling the cable, any excessive drag in the cable will cause your symptoms. Here's the link again.
Good Luck

Re: Slipping gears- help please!

I had a similar problem recently, it turned out to be a sticky gear cable caused by crud in the bottom bracket cable guide and general non smooth running through the outer cable, I replaced the inner and outer cable and order was restored. I even changed the cassette before I found the real problem.

Re: New seven speed 700mm back wheel needed

I just noticed these wheels whilst looking for something else, Shimano Alivio FH-MC10, 7 speed cassette hub , 36 hole, 130mm over the locknuts, nutted rather than quick release, no bad thing on a city bike harder to steal (and easier to adjust the bearings I believe ).
mach1 700c-622x19 rim, takes 28-42mm tyre I'm not sure if this is too wide for your brakes/usage . £30 + a fiver delivery

Not so funny when they break out and the next place you see them is on top of your freshly resprayed vintage car! Grrrr!

Re: Old (1995 bike) canti brake pads

I use these Koolstop Eagle 2 Canti, on both a mid '90's tourer and also an MTB with the same pattern of Shimano brake.
£19 a set of 4 plus postage (sold in pairs - £9.50)
https://www.spacycles.co.uk/m7b0s104p81 ... le-2-Canti
Pictured on a '96 Saracen MTB, they are 62mm long.

I didn't find these particularly long lasting when I was using the tourer all the time, a set a year perhaps, but as it says on the pack they are 'rim friendly', so presumably quite soft


I see Spa also sell these Aztec ones as a cheaper option, I've never tried them myself.

Both these are the one piece moulded type.

Re: rigid fork replacement for 1994 Gary Fisher MTB?

It looks like the 1994 Tassajara is 1-1/8'' threaded (at least for the rigid fork version ), see the Tassajara picture and spec's at the bottom of the linked Gary Fisher catalogue (courtesy of The Retrobike Forum). I don't know if the O.P's existing suspension fork is likely to be threaded or threadless as the Tassajara is only pictured fitted with a rigid fork in the catalogue.
Looking at the spec's Gary Fisher were using either 1-1/4''ahead threadless, 1-1/8''ahead threadless & 1-1/8'' threaded depending on the model in 1994.


To fit the Thorn fork (or any other threadless 1-1/8'' fork) I linked to up thread, you would also need a new handle bar stem a star nut/spacers, cable hanger, steerer cap & screw and a new headset at least.

http://www.retrobike.co.uk/gallery2/d/4 ... fisher.pdf
Some of the issues you can run into are shown here on RJ the Bike Guys youtube channel where he is swapping an 1-1/8'' threaded rigid fork for an 1-1/8'' ahead (threadless) set-up (albeit a suspension fork).

https://www.youtube.com/watch?v=OHcjh4O20ko
The simplest & cheapest way might be to put a want ad on The Retrobike Forum for an 1-1/8'' threaded fork explaining what you want to do ; assuming your existing suspension fork is indeed of the 1-1/8'' threaded type.
Good luck.

Re: rigid fork replacement for 1994 Gary Fisher MTB?

Thorn/SJS make a Reynolds rigid fork specifically to replace MTB suspension forks (with a travel of 80/100mm) , the 'Mt Tura', I have a similar twin plate design fork of theirs on a bike, it's a well made, nice springy fork.
You would need to check with them if it's suitable for your needs, dependent on the travel/length etc of your existing fork - £110.
Somebody over at the Retrobike Forum might be able to point you at something cheaper, lots of knowledge about 80's / 90's MTB's over there.

Thanks for the link Simon, I found it an informative video showing some of the science behind climbing, and a general overview of how to analyse and if necessary modify gearing .

Re: Seized hub nuts/cones

What make and model bike is it ?
you might get a clue on the hub type or a suitable replacement wheel size from the original specification, if it's on-line somewhere.
