Strida workshop tool guide

Hi Striders,

created primarily upon request for details of Schlumpf speed drive installation and required tools, the following chart was extended to a (hopefully) nearby complete list of all, usual and special, tools around the Strida workbench.

Maybe it is useful for deciding if you want to repair/maintain “her” by DIY or a professional bike store.

Schlumpf/Speed drive tools:

[size=200]A[/size] Hook spanner (hook wrench) Ø 60 mm (bottom bracket groove nut)

An adjustable hook spanner of correct size range will also do, like this

But it should be recognized that a spanner with only one “hook” must have higher quality than a “3-hook” version!
Usually a “1-hook” version is more expensive due to better material (chrom/vanadium steel) than a “3-hook” version which is stamped out of 5 mm iron sheet.
Vice-versa is that the reason for the low price of the Schlumpf tool set “Installation and maintenance” for 32 CHF which is shown above!
And also the reason why the tool set is recommendable for DIY’ers.
The “3-hook” version does have a big disadvantage (it collides with the kickstand mount), therefore is correct belt tension adjustment not impossible, but it requires several steps more.

I think that the 60 mm hook spanner is a very important tool, not only for two speed riders because the spanner should be used to tighten the big groove nut after/while belt tension adjustment.
Tightening the kickstand mount/belt tension bolt hard and let the big groove nut loose will not really do, I am sure.
A correct and durable belt tension adjusting procedure/securing without use of a hook spanner is impossible, regardless of one or two gears.
Every Strida user should use this tool for belt tension adjustment!

[size=200]B[/size] Hook spanner Ø 28 mm (for gearing play adjustment) + special key for gear shift button (for gear shift button adjustment)

[size=200]C[/size] Steel distance roll, outer Ø 11,0 mm, inner Ø 4,7 mm, length 10,0 mm
[u]Absolutely necessary for UNmounting of Schlumpf cranks!!![/u]

[size=200]D[/size] Allen key bit 1,5 mm, 1/4" hexagonal drive (for gear shift button adjustment/securing)

The Schlumpf tool set “Maintenance” is containing parts B + C + D for 15 CHF.

Additional required common tools for DIY:

[size=200]E[/size] Screw driver grip (or anything similar with 1/4" hex bit drive/connector) to drive tool D

[size=200]F[/size] 14 mm hexagon socket nut with 1/2" drive (for the crank bolts)

[size=200]G[/size] Ratchet (or anything similar with 1/2" drive) to drive tool F

[size=200]H[/size] Bolt securing adhesive (loctite or similar)

[size=200]I[/size] Allen (hex) keys 4,5,6,8 mm

[size=200]J[/size] Flat spanner (wrench) size 15 mm (for pedals un/remounting), size 16,17,18 mm (depending on your crank tool L)

[size=200]K[/size] Drift punch (pin drive) Ø 6 mm (for groove nut removal help)

[size=200]L[/size] Crank extractor tool, for example the one of BBB Powerpull BTL-14
http://bbbcycling.com/accessories/workshop-tools/BTL-14/

The small conical part must be removed for use !!!

Thread: M22 x 1,0 (fine pitch thread)
Required wrench size for BTL-14: 15mm + 16 mm (tools J)

For a semiprofessional workshop recommendable:

[size=200]M[/size] Little ratchet (or anything similar with 1/4" hex bit drive/connector) + elongation (~ 120 mm),
In combination with the tools P to save time/have more comfort while snubber bolt and rear brake caliper bolts un/remounting.
And to save the durability of the tool O!

[size=200]N[/size] 1/2" drive torque wrench, e.g. Norbar TT 100, torque range 20 - 100 Nm (crank bolts 55 Nm)
http://www.norbar.com.cn/

[size=200]O[/size] 1/4" drive torque wrench (ratchet), torque range 2 - 24 Nm, e.g. BBB torqueset BTL-73, (brake caliper bolts 8 Nm)
http://bbbcycling.com/accessories/tool-boxes/BTL-73/

[size=200]P[/size] Allen key hex nuts 4,5,6,8,mm (part of the BBB kit above)

[size=200]Q[/size] Adjustable torque screw driver with 1/4" drive, e.g. Wera 7440, range 0,3 - 1,2 Nm (for professional tightening of the gear shift button)
http://www.wera.de/catalog

[size=200]R[/size] Philips screw driver bit (kickstand height adjustment)

[size=200]S[/size] Alcohol for cleaning purposes

[size=200]T[/size] Freewheel removal tool, e. g. Shimano TL-FW45 (Y-120 09150)
Shimano.com/Tools.pdf

http://www.parktool.com/product/freewheel-remover-FR-6

[size=200]U[/size] Adjustable flat wrench ~ 10" (drive for tool T)

[size=200]V[/size] Soft head hammer, preferably wood or plastic (drive tools U + T)

[u]Special tools and alternative tools:[/u]

[size=200][/size] Elongated Allen key 5 mm, ~ 100 mm, drive 1/2", shown above
(enhanced reachability of some snubber bolts)

[size=200][/size] Bearing extractor tool, e g. Kukko 21-1, Ø 12 - 16 mm.
To be complete is a second size recommended; Ø 14 - 19 mm.
A slide hammer or a pulling device is required to drive the bearing pullers (not pictured).

[size=200][/size] Wheelbuilding tools
Measuring clockwork, trueing stand, metal ruler, caliper rule, spoke keys are required at least.

[size=200][/size] Alternative hook spanner by USAG (tool A,B)

The list above does not recognize the original Strida tools and tools which are commonly used for bicycle operating/repairing, for example thread repair tools, brake cable cutter, air pump or tyre levers.

Editing supposable…

Questions, comments welcome!

BRILLIANT Post !! … many Bike shops would be humbled by this :mrgreen:

THANKS for sharing

Thank you very much, TomT!
:blush:

…I got my friend meccanic’s shop…

iessssssssssssssssss!!! :sunglasses:

Update extraordinary tools:
(Useful for very experienced wheelbuilders/workshop owners only.)

The Phil Wood Spoke Cutting and Threading Machine

Please read more here.

This machine can be ordered here (complete with accessories) for US$ 3900…

Special tool for removing of freewheel (and beltwheel), required for Strida 3 versions.
The function is similar to tool “T” above.

just trying to fit those wonderful aluminium beltwheels I got from 5Big (thanx to Victoria) and wonder where to get this Strida-3-freewheel-extractor…

Unfortunately I do know just one source for this special tool; it’s Five Big…
We don’t have such a tool at our workshop in Vienna, but we will get one in a couple of weeks.

But there might be another option…
Could you please measure the biggest diameter of the crank spindle?
I guess that should be the part with the thread (?).

It might be possible to drill out the hole of a common tool “T”, but to be sure I need to know the mentioned maximum diameter.

its 22mm!
Fortunately my brother is a toolmaker - unfortunately he is on holiday at the moment.
I have the freewhell-extractor as shown in “T” and will ask him to modify it for me…

Thank you!

You lucky guy :smiley:
But however, I’ll try too…

This things a bitch to remove! Just tried at a local cycle-shop and they gave up! Without this special tool Id say its impossible to open.

It was actually no problem to lathe the 22,6 mm diameter - used were chisels with hard metal insert.

Choosing a tool with maximum key size seems highly recommendable; by using a 28 mm key size tool there will be just ~ 2,6 mm material left over for the hexagon.

For driving of such a weakened tool it will be advantageous to choose a ring wrench, not a common flat wrench!

:wink: you’re welcome! it was very nice and happy to met you and your lovely wife at Eurobike!!

Finally, after long weeks, I managed to finish my Strida.
Was busy otherwise (so no time for the workshop), needed my brothers help to adapt the freewheel-extractor, also needed some advice from the local BMX-shop…and now - here it is:

…sorry. somehow the image is cut…but the 5Big beltwheel you can see…

Well done, very nice look :smiley:
Do you have also pics of the custom tool?
For the image cropping issue please refer to here, point 2. + 3. (size was actualized!)

My custom-tool looks just like your Shimano-tool drilled out inside.
The main difficulty was to remove the BMX-freewheel from the axle:
not knowing exactly how it was fitted, I asked the local BMX-shop for help and they showed me!

Well, thank you very much for the info :smiley:

it looks very nice, but if I have second chance, I may recommend other colour, to let your Strida more beautiful :wink: and thanks for sharing.

Hi,

Thanks. Is the BB tool available online? I have difficulties finding it locally.

Hello Stccmc,

nice to see you here, welcome :smiley:

If it’s correct that you’re from Hong Kong (?) then you should be able to find a suitable tool locally, I mean…

Did you try your local web search with the (translated) words “hook spanner 60 mm”, “hook wrench 60 mm”, “hook key 60 mm”,
maybe “adjustable spanner wrench”, “adjustable ‘C’ hook spanner”?

You might of course also use an adjustable hook wrench of matching size (range), for example

http://www.skf.com/group/products/maintenance-products/mechanical-tools-for-mounting-and-dismounting/bearing-fitting-tools/adjustable-hook-spanners/index.html

(If possible, check the dimensions of the tool’s hook - or nose - to fit the slot of the big groove nut.)

Hopefully you could find more info with the links above,
these hook keys are also used for some motorcycles - should be available at the tool suppliers of workshops.

…and did you already ask Strida Hong Kong?
G.U.M.
