Dave!

Its all in the knees, gotta get them tucked in! Also trying to reach out with the back wheel to effectively shorten the gap. ( If that makes sense.)

.

ISIS are stiffer, and are suppose to be better because they have the grooved shape. But they are more expensive. Although I've always just used square taper BBs', mainly because it was cheaper. But over the years I've found they are just as good in the long run, especially if you get a decent one with good bearings. I've had my Shimano UN53 for about 5 years now....no problems at all. Hope this helps.

There is more to it than just being better for ground clearance etc...Although these are advantages. FFWs' help with engagement, in the sense that its quicker. (bare with me) Having the freewheel up front reduces the distance from the cranks, so when you pedal the pawls can engage faster. (regardless of engagement points) Having the freewheel at the rear means by the time you've pushed down on the pedal and the kinetic motion of the chain has reached the freewheel you might as well have lost an engagement point. To put it simply, freewheels at the rear mean more play at the cranks. Unless I'm just making up a huge chunk of physics.

Had my tensile nearly 4 years, still runs as smooth as the day i got it. I'd stick with it...

Just divide the front by the rear to determine if the gearing will be too hard/easy.....i.e 18/12=1.5. So every turn of the cranks turns the wheel 1.5 times. Where as my bmx has 28-9 ratio.....so thats like 3.1, twice as hard to pedal. Just comes down to personal preference I guess. But as said above 18-12 is what most people use.

Yeah, sounds good.

Havent ridden in like a year or so, but i'm in for the 4th... Do we have a time?

Cat trials, interesting.

Once or twice a week, about 5-10 hours? Used to ride everyday at one point.

Sounds like a good setup, Pritty good price too!

I remeber the old T-birds, the seats were MASSIVE. Think it was late 1990's/2000. Rode pritty well as I recall.

The 20" ashtons look foul IMO. But for £80 you can't go wrong, Bargin!

Lucky gits, I don't even have a garden!

A benny hill tune would be funny. Speed up the vid, and get chased round.
