Re: Disc brakes pads left and right

Mechs can be top pull and either bottom swing or top swing. Or bottom pull and either top swing or bottom swing. BTW the only confusing thing about top swing and bottom swing is how anyone could possibly get it wrong. Well I defer to your greater knowledge. So for my benefit what are the advantages...

Re: Which Brompton tyre make/model are easiest to fit

Marathon Racers have little of the "marathon" name, being lightweight and with supple sidewall (which can be a bit fragile), so are fairly easy to fit especially on the new rims where the inner width is fully usable.

Re: V Brake failure

You can reshape that part, and once you fit the noodle (flexy ones can be made with the start portion of some Jagwire cable kits, or bought as new part anyway) you can use a small ziptie to keep the end of the noodle well inline with the yoke. A noodle that's not inline will often cause this problem...

Re: Square taper BBs

hard to beat BB-UN55 for the money. However you can 'improve' them by filling them with better grease before installation. cheers Same you can do with external-cups bb's. It all depends on which ones. I have been running five years on my Power-Torque bottom bracket bearings, still butter-smooth and...

Re: Mid fork rack mounts

What is the inside diameter of the tube? Will an M5 bolt pass through? If it does you obviously could not thread at M5 and would need to go to M6. An M6 bolt might not pass through the holes on the rack though. A passing-through boss is actually a better option, if brazing is correctly done (and a ...

Re: shimano freehub internals

Play in the freehub is detrimental, because it is what leads to the pawls becoming misaligned and crack, or makes their spring to crack. The difficulty in this is the narrow width of the shims, being barely 2mm (IIRC) between their OD and ID makes very hard to cut them by hand with scissors (commerc...

I use a wooden spatula: great for making scrambled eggs and clean after. £1 from Wilko, can't go wrong with it! :wink:

Re: 3d printed hollowtech BB spacers OK ?

If the BB has a BSA thread it couldn't be easier: use some 10sp cassette spacers, Sram ones are excellent because have a round ID. More difficult is for an italian-threaded BB, you'll have a hard time finding a 35mm ID spacer. But rather than messing with the chainset, altering the chainline and all...

Re: Seatpost size for old Btwin Rockrider bike

I won't be surprised if the seatpost is a 25.4mm size, a cheap frame ought to be made with thicker tubing. And would not advise to measure frame with verniers, unless is to give a rough idea to narrow down the hunt for the correct size. This is due to the possibility that the end of the seat-tube is...

Re: Pedals hit front wheel

The pedal hitting the front wheel can be or cannot be a problem, it depends if the bike was designed to (for example, on a race bike is irrelevant) and how the user can cope with. That bike is a 29er mountain bike. It is designed to go offroad where you've most unlikely to make a tight turn while ke...

Re: Grease freehub pawls?

I've used Finishline green chain oil on similar pawls in my Mavic Aksium rear hub. Still creates a little drag when freewheeling though, visible as the top run of the chain dips slightly. The semi-fluid grease suggestion sounds worth a try. Following a recommendation elsewhere on here I bought a sp...

Re: Which Brompton tyre make/model are easiest to fit

...Older Bromptons rims have a deeper well and make tyre changing easier. Newer Brompton rims are lighter, stronger, and make changing tyres worse.... It is actually true the opposite. The older single-wall Brompton rims had a narrow well, and using a very narrow strip of rim tape this was prone to...

Re: Mid fork rack mounts

A passing-through boss is actually a better option, if brazing is correctly done (and a steel bike from the '90s is most likely so) it acts as reinforcement so it's better. You are to use a long bolt, and use a class 10.9 bolt (or Stainless 304 is acceptable) for improved strength, and long enough t...
