Swapping a Crank - Giant Defy 0

Hi all, I have kindly been offered an ultegra 6800 crank set to replace my non group shimano crank set. The bike is a 2016 Giant defy 0 aluxx sl. My bike and the ultegra crank belonging to my friend are similar in age and milage which is may be 250 -350 miles. So nothing too drastic wear pattern wis...

I'm interested in a bar mount or helmet cam too.
Any more experiences out there good or bad with a budget sub £150?

Re: Bike adjustments, where to start?

I'm rubbish with terminology but Decathlon do a pedal with mountain bike stle cleat on one side and ordinary pedal on the other side for £25. Their return policy means you can't go wrong. Can't help you with braking. You will use the inner chain ring if you find a real hill. Not worth the cost of mu...

Re: Who pays 14x as much for an 'equivalent' item? And why?

Crikey that is a question and a half isn't it. Ultimately probably like many others my finances dictate a limit. So my spending varies based on the item. I'm likely to spoil myself when I can afford it sometimes regardless of rational thinking. Equally sometimes I flatly refuse to spend a penny more...

Re: Preventing seat post Seizing?

So the consensus appears to be 12m unless you have extenuating circumstances so far then.
Thanks everyone.

Re: Preventing seat post Seizing?

So experience from you guys here say the seizing is predominantly due to the after effects of wet /cruddy conditions seen by the interface of the seat tube/post?
Secondary to this it's the reaction between materials hence it can happen to bikes with dry (albeit dusty) miles?

Preventing seat post Seizing?

I read that no matter what materials, seat posts can seize into the seat tube.
What is an optimal period to check / replenish the grease without wasting your time?
Is it grease that you use?
Whats the shortest time period some you had an issue in?

Re: Tyre clearance when changing brake callipers

I have a pic.
It doesn't really show the clearance but lets say 1mm top centre of tyre.

Re: Hollowtech Chainset Question

Hi Thanks, so am I right to think that noticeable play in the crankset isn't necessary for this type of damage? Regards tim-b Correct, your issue is not necessarily down to this type of corrosion but as Brucey says, once damage (whatever the cause) is there and you have 'play' that will get worse s...

Re: Tyre clearance when changing brake callipers

Brucey wrote:BR-6800 has a reach of 39-49mm, whereas BR-R561 has a reach that adjusts out to 57mm. Thus if your brake blocks are presently set in the lower 8mm of the slots, a BR-6800 caliper won't fit your bike at all, never mind the tyre clearance....
cheers


Oh I see, thanks Brucey I'll look at that.

Re: Hollowtech Chainset Question

Hi have a fairly experienced opinion. Not much experience with bike maintenance but a fair bit with bearing and shaft degradation in the aircraft industry. For sure Fretting corrosion is a likely shout. Accompanied with moisture ingress you'd see conditions like your photos. Fretting is caused by vi...
