I've got a regular short ride in my neighborhood that's mostly hill:

It's all new houses up there, with empty lots and construction projects. How the housing market will fare under the changing financial situation... we shall see!

We are at the end of our first lockdown period in Spain, about to begin the second. It is a tight lockdown but those with jobs which cannot be performed from home have been allowed to go to that work. From Monday even those workers must stay at home so the means of production apart from essentials and the essential services will shut down for 10 days.

Given the way I cycle, I know my current front v-brake will support an effective emergency stop in all conditions I would choose to cycle in, so I don't need a front disc brake.

If v-brakes are adequate, perhaps it be easier to have them front and rear (the Nomad frame supports this see the 26 Nomad in the latest mega brochure, which looks a lot like my current Sherpa).

That said, the disc fork can handle larger tyres to match the rest of the Nomad frame, but do I need tyres which are bigger than the 50mm supported by a v-brake fork? Would an extra 10mm (i.e. 60mm tyres) add significantly to comfort?

The disc fork looks purposeful and seems to suit the Nomad, but the simple, straightforward lines of the 853 fork appeal too.

In answer to your question PH, I'm not really sure!

A number of businesses here (US) are folding from the loss of customer traffic and it seems to have hit bike shops hard. I just received emails from three well-established firms that are going out of business or on the cusp of it.


Yes it's a tough time for a lot of businesses, I'm sure many of them won't survive.  When we get through this it will be a different world.
On the up side, the market stall I sometimes buy fruit and veg from have started doing deliveries, apparently they've had a record week!

The only time I've had a crank bolt loosening was down to a poor fit between crank and spindle, the crank squirms on the spindle taking pressure off the bolt.
The surest way to test that is with a swap, the same crank on a different BB, or a different crank on the same BB.

About a decade and a half ago, I was riding a bike that I had recently built up.  And I noticed a slight squeaking noise down in the pedal and crank area.  I had a multi tool with me, immediately stopped and started checking everything down there.  The drive side crank arm bolt was pretty loose, I tightened that up as tight as I could get it with that small wrench.  And went home and used a torque wrench to tighten that bolt to specification.

This would not solve your noise problem, but I can say that when i tighten that bolt on my bikes with a torque wrench, the bolt stays tight enough that it stays in the bike and does not fall out.  But the bolt will be noticeably looser after several hundred miles.  I never worried about it being looser since the crank arm stayed in place and I installed it to manufacturer torque specification.

I suspect (this is only a guess) that the crank arm slowly tightens onto the square taper spindle over time because the bolt continues to apply pressure against it and that was enough to cause the bolt to become slightly looser with some distance on the bike. 

Since then I usually use a torque wrench on crank arm bolts.  The exception is that when I take my bike on an airplane I have to remove the crank to fit it into the case, for that I do not use a torque wrench as it is too big and heavy.

I have heard that if you ride a bike with a crank arm bolt too loose for too long, that can damage the crankarm.  Fortunately the one time I did that, I did not ride it enough to cause damage.

Does seem a little odd for them to be selling a 650B rim brake fork and saying the complete bike is disc only, there might be an obvious answer but it hasn't occurred to me.
The 700c AB brochure also has an oddity, the fork on the pictured bike isn't the one in the description, maybe they were experimenting.
So - Even though you're just looking, which would you go for?

Thanks for the response. Yes it's a square taper crank set.  The bike is eight years old, the bb was replaced last yrs.  The none drive arm also had to replaced recently. Its possible the drive side could have been run loose.

Thanks Kyle, similarly, these forks are v-brake and stated as 650B/700C and Nomad compatible:

Either way, it's not clear why a Nomad Mk3 650B should be front and rear disc brakes only.
