Polo Bikes

Finally! Nice work Jimbo. Shame I wont get to have a go.

Jimmy, remind me, what bike did you have before the blue NS?

Raleigh Dynatech XC MTB for a few weeks. Before that it was a 700C trackbike.

Jimmy, that looks fucking awesome, you should be over the moon.

All came together, didn't it!

pity you bough it from specialized in the end.

Clem!!

Do a 3D model to check the pedal overlap, i did it with solidworks, it worked out perfect, exactly what I wanted, +-3mm of overlap, nothing you can't avoid with freewheel.

-front end 595mm (+-1mm)
-crank lenght 175mm (mtb cranks are wider, Q factor affects as well)
-700x32c
-foot size 43

nice one Jimmy! Does it barspins?

Bike looks good Jimmy. I look forward to putting some dents in it at Newington.

650b?! Scoble played that out early 12. Move on.

Scobble is an innovator, we are mere early adopters

Mind you, track frames with 650b wheels and a slightly wider tire might work wonders since less and less peeps are using rear brakes and discs allow any size wheel. I should have kept my langster methinks.

So i'm thinking of putting a 26inch front wheel and fork on my pompino and want to calculate whats the best rake i can have on the fork whilst reducing the quite high amount of toe overlap i currently get. how could i calculate this? also how have other who have done the same found the switch?

Make a pomp in bikeCad then fuck with fork measurements.

Wot otters utters

Landslide has done the 26 front swap on a pomp & likes it.

Dunno his numbers

We've had 4 or 5 like that in Birmingham, all sizes of pompino, and nobody ever goes back to 700c on the front.

But still with a 700 rear?

But still with a 700 rear?

If you put 26 at both ends the angles don't change.

Yup, 26" front, 700c rear. I'm using a Milwaukee Bruiser fork which is designed for 700c wheels, but as I'm using clamp-on canti studs, I just moved them down the fork legs a bit.

But still with a 700 rear?

Yep.

I see. One of the lads from Party Illuminati does that too, IIRC.

Advantages being: less toe overlap? easier to turn / less jacknifing?

Less overlap plus the usual changes caused by steepening the headangle.

I did it with the smallest tyre i could to steepen the Head angle. shortened my wheelbase by like 2 inches. I grinded the dropouts further too to pull the wheel in. All in all, makes it awesome to ride.

shane from party illuminati has done it to a create. it feels really good

Does Eddy from Eddisons have a 700c rear/26" front custom build or am I just imagining it?

The downside of 700c/26" bodges is generally a lower b/b, although that depends on which tyres you use. Having got used to my 300mm+ b/b height I couldn't possibly go back to anything lower.

eddy runs dual 26

For those who have not seen my finished bike yet....jimmy inspired me....
