Re: Identify this frame - next Resto

What point restoring it when it is hopelessly too big for 99% of the population?

Re: London cycle parking security

Incidentally, although there must be CCTV coverage of the area, the police will not look at it due, they say, to not having sufficient officers to look through 2 hours footage, and when I said I would be happy to spend 2 hours doing this for them, they won't allow that. So no chance of finding whoe...

Re: SRAM new 'AXS' for MTB/road

even more hilariously, SRAM's solution for power metering (you wouldn't really buy such gubbins without a power meter, let's be honest) is to incorporate the power meter into the chain ring. So when you wear out one chain ring you not only replace your unworn chain ring but also your power meter Th...

Re: BB30 bottom bracket observations

Manufacturing costs are, I would think, considerably higher for BB30 than traditional threaded bottom brackets. Hence the move to PF30. BB30 is the lightest of any system out there. That is the point of them. Not durability. New BB30 bearings are only cheap. And more durable ceramic ones not too cos...

Re: Bottom Bracket woes

In the case of some square taper bottom brackets the LH isn't meant to screw all the way in and correct fitting leaves threads on the cup exposed. Read instructions.

Re: Decathlon Chainstay/Seatstay Pressing?

Just a design feature I would think. Maybe with the idea of allowing a little clearance reducing the possibility of the chain rubbing any part of the frame. Also helps reduce the possibility of user scratching paint off the inside of the chainstay everytime wheel is removed. Both chainstays and seat...

Schwalbe one doesn't seem to have a bleed button. No point for it existing.

Re: Cyclus head tube reaming and facing tool

Check out page 18 of the 2019 Cyclus catalogue, available in PDF. The 'regualr' Cyclus headtube reamer/facer is exactly that - all the cutters for it are combined reamer/facer units that cannot be separated. Buy the Snap-in version is different - takes separate facer and reamers. But not sure if the...

Re: Reflector light

Why on earth bother clipping on and off for charging? These type of lights typically take 2 x AA batteries and last for several years with regular use. There are an awful lot of people riding round with AA-powered rear lights with several years old batteries that are very dim indeed. They turn them...

Bicycles are supposed to be easy to ride. The term 'fatal flaw' springs to mind.

Re: Carbon damage

Looks like the paint has chipped off. There will be a few who will say they can repair that for you. Get on with riding it. Not as if it is the fork What the hula-hula have you stripped it down for?

Re: Limit screw size

I would expect these to be still available as a spare part.

Condor Cycles
Mercian Cycles
UK Campagnolo Service Centre

But sometimes they are missing from a second hand derailleur you have bought because the threads (in the derailleur) have been damaged.

Re: Replacing BB30 bottom bracket

Note that with 'proper' BB30 two cartridge bearings sit inside the BB shell - no cups.

The other style is Press-Fit 30. This is where the bearings are retained in cups which get pressed into the BB shell.

Both styles take a BB30 crank.
