Re: Replace Brompton 2019+ crankset advice

cheers

1. Will i be ok with this budget option tool ?
https://www.ebay.co.uk/itm/164284562815 ... %3A2334524

2. I think this is the right video as a guide to follow ?
https://www.youtube.com/watch?v=dvMkVi5 ... el=BIKEHUN

3. When i put the new spider on - do i just place it on and, apply grease & tighten the bolt with the allen key to 30Nm ? Or - do i need to do a reverse routine with the crank extractor too ?





cheers :D

Replace Brompton 2019+ crankset advice

Hi

I want to replace my Brompton 2019+ folding bike crankset from the silver to black. The transmission remains the same.
1. Is changing the Brompton 2019+ crank drive exactly the same as changing other generic bicycle cranks ?
2. What is the name of the special tool which appears to be needed to undo one of the inner bolts ? Is this a universal tool too ? Any advice on tools welcome.
3. Does anyone know of any walk-thro instructions anywhere online ?

Cheers

Matte/matt frame protection tapes

Hi

I've shortlisted 5 types of frame protection tape based on reading forums:

1. 3M 8671HS - otherwise known as 3M's standard helicopter tape
2. 3M VENTURESHIELD - 203 and 355 micron thickness option - also used in Invisiframe products / seems more recently to be called bra ?
3. Suntek tape - i don't know about this product
4. Rhino-Hide tape - mixed reviews
5. Paragon tape - not many reviews

My issue is that my frame is matt black and the M3 products i favour apparently no longer come in matte, only high and semi gloss.

Seeking folks feedback about using them AND suitability for matt frames.

cheers - appreciated

Re: What crank extractor do i need for my brompton spider crank ?

Hi ......ONE FURTHER QUESTION !

While i'm on this replacing a crank set learning curve...... can i ask for some advice about bike grease vs oil. My understanding is bike lubrication hot spots are basically split between the two .

Is this correct:

1 Grease for : (?)
crank extractor thread
pedal thread

2. Advice seems divided about applying grease to the bottom bracket once the crank to be replaced is removed - it's a new bike so i'm assuming NOT to add grease to the bottom bracket ? It's also a new crank set so should i add grease to the crank arm mounting port/hole ?

3. Do i need to put any grease OR oil on the new crank set chain cog or will the existing oil on the chain be ok ?

4. Can you link me to a reliable but inexpensive grease product - i gather grease has a shelf life so i don't want to over buy and be left with off-grease in the future.

Any other grease/oil advice not already mentioned welcome.
thanks again.

Re: What crank extractor do i need for my brompton spider crank ?

thanks folks

i'm going to purchase the Ice tool alexnharvey linked me to above unless anyone says different. I'm assuming the taper head is compatible with my Brompton.

I think that about covers it unless anyone has anything else to add !

Only to thank you for your time.
cheers

Re: What crank extractor do i need for my brompton spider crank ?

Hi that ice toolz one you linked me to - if i purchased that all i would need is a spanner to grip the thing with and turn - is my understanding correct ?

Also i'm browsing youtube vids using searches like how to use a crank extractor - this one seems informative on procedure :
https://www.youtube.com/watch?v=cPQyQnNdews
this one on crank identification:
https://www.youtube.com/watch?v=VMV-SOIhM2c
i'm assuming the brompton is a 3 piece type

if these are wrong, if anyone can link me to one they think covers it - appreciated.

cheers

Re: What crank extractor do i need for my brompton spider crank ?

Thanks.

1. What's the pushing pin ? I've not heard refs to that before ?
2. For the extractor tool head-taper type - i found these on ebay - which would you recommend ?
https://www.ebay.co.uk/itm/Bike-Bicyle- ... SwuRpe2yE~
https://www.ebay.co.uk/itm/Bike-Bicycle ... Sw1SFfBZjh
https://www.ebay.co.uk/itm/Icetoolz-04S ... SwU8ReXnk4
They all look a bit cheap and chearful but will they do ?
3. I understand this is only used to remove - when it comes to mounting the new crank i don't need to use this tool . Is that correct ?

thanks

frame protector tape: 3M 8617HS vs 3M Ventureshield

Hi

Any comments or feedback on experiences with or recommendations for 3M's frame protector tape.

The two recommended to me have been
1. 3M 8617HS (Known generically as helicopter tape - comes in clear)
and
2. 3M Ventureshield (reported (but not verified) to be used by Invisiframe - seems to come in gloss and matte)

3M ventureshiled seems less costly per meter but i have no knowledge or experience of using these products.

cheers folks :?

Chain Locks - Length measurement question

Hi

Can anyone confirm the following regarding indicated chain lock measurements in general.
Where product descriptions state chain lock length as for eg: 55/85/95 CM - Does this figure usually refer to length of object end to end or just to the chain length section (i.e. doesn't include the length of locking barrel ?)

Examples i'm looking at are:
Kryptonite series 2 mini
https://www.kryptonitelock.com/en/produ ... 00822.html
and
AXA cherto city range:
https://www.axasecurity.com/bike-securi ... city-100-8

Unless answer is common knowledge, real world confirmation appreciated.
Thanks for your time and attention.
