Functional bikes. Not Porn not Anti

spokes tension is too high and will crack it.

You can tell, by pictures on the fucking internet, that his spoke tension is too high?

What are you? A wizard?

Look at the first picture, front wheel - assume the bulge in the rim around the nipples is what he's referring to.

Well good though

I'll see the bike in the flesh on Wednesday. Maybe I'll ask Kumo Keith then.

Indeed, the Pacenti rims is very thin, they're great high performance rims, but will crack eventually if the spokes tension is too high over Pacenti's recommended tension, the bulge is normal, but the bulge on that bike is quite big.

Had a pair, my rear look like his front, but my front have a lots less bulge due to the spacing and lower tension, the front despite having a worn braking surface still remain true to this day and only be trued once after 4,000km.

But the rear have to be retired after discovering a lots of tiny crack on the spokes hole after 2,500km, that's largely due to the hubs spacing and offset that required a higher spoke tension (130mm with 10 speed hubs).

Well good though

Not denying that!

Tubeless friendly too, you should ask him to convert the Pacenti for tubeless, the GB Hetre work well as a tubeless set-up.

650B tubeless;

The Bob Jackson sounds good, but I have a nagging feeling this thread should be split into a) truly 'functional' bikes and b) nice-but-pricey steel 'randonneur' porn (or 'bikes with a front rack', as we called them back in the pre-Cambrian era)

And make even more niche topic?

Best make a current project topic instead.

Niche but pricey

If 25mm tyres work well on 25mm wide rims what about 35mm tyres on 35mm rims? Does it have
the same advantage?

something like this with a marathon supreme tyre:

I have discussed 35c on a 35mm rim with my LBS, they said it should be fine and the tyre would have a nice profile.

Velocity P35/Blunt 35 were the rims being discussed at the time. We figured it would be possible to run them with 35 or 42c tyres on a Straggler or 2.4/3" rear/front combo on an Ogre.

cool! what rims were you thinking of?

Incidentally I have experience such ideas as well.

Currently the 23mm (18mm internal) work great with 23mm tyres as we know.

But I try bigger (25mm on 24mm rims, 19.5mm internal) and it work out the same, lower pressure, more comfort etc.

Ditto with 28mm tyres on 24.5mm rims (21mm internal), the shape remain nice and round, this one was on a CX bicycles and the pressure is even lower, the rear have 70psi and the front is 50psi (75kg), it felt nice and stable without squirm, absorb the road so well that I notice my companion on his 23mm rims/tyres combo took a bit of a beaten that I didn't notice.

The only issues is the caliper brakes that may not be able to work well with very wide rims, I just about managed with the Mavic A319 with Campagnolo caliper, it took a bit of fiddling to get the modulation and power sorted.

Last issues is the frame/fork clearance, which isn't common, but something you should look out for with wider rims creating a wider tyres.

Disc obviously have no problem, so go crazy.

However, HED released the Ardennes Plus SL with a whopping 20mm internal width, put a 23mm tyres on and look what happen;

You obviously lose some height though, so it's not really a 27mm tyre.

My Michelin Pro Optimum tyres (marked as 24mm) measure 28mm on Open Pros. Maybe more after a few months.

Not sure seen this posted, looks ace and not too pricey

^ did you get that e-mail too?!

I get the CTBM mailshots if that's what you mean?

Functional or versatile?
