thanks for advise on frames but how about cranks middleburns square drive or tensile isis splined

[Davey]

I've been running middleburns for about 4 years now with the pro trials bashring (half inch thick) and they have never failed me. They're stiff as you like, they look absolutely stunning and I just fitted mine with the new titanium 16 tooth chainring/bashring, which is real light and looks superb!

I've never tried tensiles, but I hear they are also very very good. There was a review on MBUK website which said that middleburn are the better crank but there's very little in it.

To be honest, the difference is in how they look more than how they perform as they are both superb choices, so it comes down to which you prefer and which is cheaper (not sure of prices)!!!

That's my two cents!

Forgot to mention, my middleburns are the square taper variety, with good old Shimano UN57 BB

If it's for stock, i'd say Middleburns.

Never heard of any snapping.

I'd also recommend ISIS drive. Much less of a chance of rounding the tapers.

Rounding off tapers really won't be an issue with Middleburns, I've had a few pairs of cranks round off in the past but I don't know of anyone who has rounded off a pair of Middleburns (let me know if you have, I could be wrong). The ISIS cranks are slightly more expensive and the bearings in ISIS BB's are larger and more prone to wear and tear than square taper BB's, so I would personally recomend square taper!

The bearings in ISIS bb's are smaller aren't they? (it was probably just a mistake though, you seem to know what you're on about). I'd go for square taper; they are cheaper, I doubt middleburns will be that easy to roud off anyway, and also with ISIS bb's after you have taken them off a few times they start to go a bit slacker as they are not tapered. Whereas on tapered bb's you can just tighten the crank up a bit more, further on to the taper.

go for the middleburns. i have ridden them since i got into trials nearly four years ago and iv never had any problems with them. get them in square taper because as the judge said there are smaller bearings which are easy to disintegrate under high loads(iv minced 3 on my dmr dj), unless you get one of those new outboard bearing isis bottom brackets.
