Thanks for summing all this up nice and succinctly. Most useful article I’ve read all day!
Hi, Relja, great article thanks a lot! Between marketing “technologies” and reality it’s easy to get lost. I’m still a…

Excellent article. Any idea why cable housings labelled “Shimano SIS” would be spirallly wound (like brake cable housings)? I was…
The number of sprockets won’t be a problem. The amount of cable pulled could be: 11 speed rear derailleurs require…

Thanks for replying! I don’t think 1.75″ or even 1.5″ tires would actually fit my bike. It is like a…
I don’t know. Different manufacturers, even different models of the same manufacturer, often end up with different widths (and heights)…
Thank you for this helpful article. I have a 1991 Giant hybrid. The tires are original and they say 26…

You are so detailed I love it

Is it possible to use a hub gear twist shifter such as Nexus 8 with an 8 speed rear mech?
Thanks, Greg. All good ideas that would work, better, or worse, depending on one’s preference, and availability of tools. :)…
Measuring the circumference of the post and dividing by Pi is a good method. There are even circumference tape measures…

I wrote a separate article about rear hubs, where OLD (or “spacing”) is noted and explained in a bit more…
Note on fixed gear/single speed/track bikes the rear hub spacing is still the original 120mm. This is the same as…
Hello, First appologies – your comment got put in the “spam” section (no idea why, computers err too I suppose),…

Thanks for the fast reply Relja Would the Tiagra 4600 shifter work with the claris r2000 fd? Thanks Regards Nabiel
Hi Nabiel, I’m afraid Tiagra shifters won’t work with the Claris compatible derailleurs (and vice-versa). Regards, Relja

Relja, Yikes!, I am reading it again your article above. Online store leads me to this – > Chainring for…

Thank you for the feedback – it’s very good. I have edited (in fact corrected) the article. I think, thanks…

Hi guys, indeed – this one : Y1RB98020 Lock Ring for 12T Top Gear thanks for reply. well, I have…
What Fabrice said – you will need a (slightly larger than 11) lockring for 12T sprocket. Apart from that, since…
Hello Eduard, It will be OK. I’m not sure whether the shifting will be just acceptable or perfect, though. Anyway,…

It depends. I wrote on that topic in the article: Are narrower tyres “faster”?
So, which two wheelers performance is better? Two wheeler with bigger tyre or two wheeler with smaller tyre?. Please give…
My back sweats when I don’t carry a back pack on a bicycle. Come to think of it, just about…
Shimano Tiagra 4700 shifters won’t work very well with a Shimano Claris FD. Older Tiagra shifters will work.
I mean “thickness” as in “how much space it takes on the freehub”. Looking at the dimension going from the…
what about using a claris fd with a tiagra drivetrain?
‘Spacer thickness’ means ‘Thickness of spacer groove’? Sorry I am not good at english. If you didn’t mean it, how…
It makes sense – narrow wide chainrings only come in even tooth counts (no odd ones), for exactly the reason…
Correcting error: meant to say 3/32″ where I wrote 1/8″. Apologies.
For the purpose of Narrow Wide drivetrains, should more consideration to the width between the inside edges of the “outer…
