Re: Front and rear derailleurs for my retirement present (to myself)

You could use Shimano 105 10 speed Triple STI ... if you tweeked your chainring combination, to say 24/36/48 (this is what I use). This is because the 105 triple FD needs more of a jump than 10 teeth from middle to outer. I use my 105 FD with Ulfegra GS RD and Ulfegra Triple STI. The Ulfegra Triple ...

Re: Viner with non-standard alu steerer

Were you trying a 1" star nut in a n 1 1/8" steerer? If the steerer is aluminium it is much better to use a bung as opposed to a star nut because of the smaller ID than you would get with a steel steerer - thicker wall. Hope HeadDoctor bung is really good for aluminium steerers. Fits the I...

A bike shop isn't going to have seat tube reamers ... a framebuilder will.

Go on major roads in northern Italy and you will die.
Go on minor roads in northern Italy and you might die.

Note that the Autostrada designation in Italy - blue signs - bars cyclists from lots of roads/tunnels.

Re: Changing to more recent Campag. shifters

'15 year old front mech'?

Your kit is outdated and trying to keep it alive can be an expensive frustration. I switched from Campag 10 triple to Shimano 10 triple a while ago.

Re: Poor frame design?

Other shoes/pedals might put your feet further out, so giving greater stance width, or Q Factor. An internet search might show which combos favour greater stance width. Some pedals also allow for the insertion of 'pedal washers' on the threads, but be cautious about this because some pedals do not h...

Re: Rear light for hub dynamo

Bonkers. Not only is a dynamo rear light substantially more reliable than a battery light, you don't have to make a special stop to turn it on. You can get permanent/battery rear lights with automatic (daylight/motion sensor) function, just like you can get automatic rear lights that work off a dyn...

Re: lugless 531 frame

A fillet brazed/lugless frame will, I think, always be weaker than lugged, but the consideration is almost irrelevant in as much as both ways of joining 531 make strong frames that will pretty much last a lifetime. But take a lugged and a fillet brazed frame into a lab for destructive testing and I ...

Re: Rear light for hub dynamo

Bonkers. You fit a permanent/battery light at the back, eg. B+M permanent and just use the dynamo for the front light.

Roller Brakes

Do all roller brakes fit onto roller brake hubs using a standard four bolt pattern? Or are there other standards/ways that roller brakes fit onto hubs?

Thanks.

Re: Mudguard sizes I’m confused

26" = regular mountain bike wheel size 28" = 700c wheel size, like with hybrid bikes and road bikes I believe your bike is a hybrid with 700c wheels, so you will need 28" mudguards. Expect to find 700c marked somewhere on the tyres. The 28mm, 35mm, etc refers to the width of the mudgu...

Re: Alpine double - what's that then?

Looking at this another way, the big ring of a SRAM MTB double chainset is at 52.5, the small ring is at 44.5 the chainline of a Shimano road triple is 45mm which given the 8mm spacing mentioned above puts the big ring at 53mm. So the chainline for a SRAM MTB double is very similar to that for the ...

How long you out riding for?
