Bob Jackson Audax Club tyre clearance (28?)

Hi there,

I'm close to pressing 'go' on a Bob Jackson Audax club frame and asking this question in a few places in hope of an answer.

While it's nominally a mudguard bike, I'm speccing it as a summer bike with oversized tubing, no mudguard or rack eyelets, hoping to run 28mm tyres.

I've gone for this over the Olympus Road - their typical summer racer, as the Audax Club is described as taking 25mm tyres with mudguards and normal reach brakes, while the Olympus Road is 25mm with no guards. My current bike takes 28mm tyres with normal brakes (Ultegra) but is being replaced as frame's a bit big.

They have advised this is achieved by having slightly longer chainstays and suggested would be the wiser choice if I want more clearance than the Olympus Road offers.

So, does anyone have an Audax Club and tried 28mm tyres? (without guards)

Cheers!

For what it's worth I had 28mm tyres on my Olympus road. Clearance was small but alright. For me the brake calipers was the limiting factor.

That is interesting! It is certainly tempting to go with an OR instead. Though they said I can have the nice upside down 'V' shaped brake bridge on the Audax Club anyway so with the OS tubing it's essentially a hybrid of the 2. They mentioned oval chainstays to increase tyre clearance but I'd rather go with round (don't know if 'round' means fully circular, but rounder tends to be stiffer)

Anyone else? ;)

I would assume you could fit 28s, you spoke to Bob Jackson yet?

Yeah, they have suggested yes but are non committal. I would assume so too but hoping for some real world confirmation. Ta.
