Isis Bb


Jack Morton

Recommended Posts

The bearings in my BB shattered last night, So now in need of a new BB. I have narrowed it down to a

Echo TR ISIS

Neon ISIS

Try-all ISIS

Which would be the one to choose. I was thinking Try-all as the bearings are also replaceable in it. What do you think would be the best to go for.

I know it's not on your list, but I've been using a Moe isis for about 5 months now, i got it pretty cheap off ebay (just came across it by chance and decided to give it a shot). It's similar in spec to the echo tr, but lighter. Has been good, it's still running smoothly despite the hideous weather i ride in daily, can't really complain.

I use a truvativ giga pipe dh which is pretty darn alrite. Quite heavy but fairly strong. I have recently learned that Danny Macaskill has or does still use one.

Personally i think it would be nice if we started moving over to hollowtech now. I've always used splined or chainring type cranks so i'd me more than happy to move over, i'm not sure how it would effect the screw on types.

Listen to Matthew! Gigapipes are bombproof. Mine's been in my bike for a year and a half and is still going strong, It's amazing!

Where do I find one of these " Gigapipes " as tarty don't seem to sell them.

Neon's are well priced and are pretty durable. But i know nothing, ask TartyBikes.

Neon was also my previous BB but it was a previous model to the one shown on Tartybikes I believe as similar but not the same.

EDIT: found these Truvativ Gigapipe on ebay but there is two diffrent measurements

Truvativ Bottom Bracket Giga pipe team DH isis 128 x 68

Truvativ Bottom Bracket Giga pipe team DH isis 128 x 73

OR AM I LOOKING AT THE WRONG MODEL ?

Also with a Truvativ Bottom Bracket Giga pipe DH is it possiable for me to run FFW as I currently am.

I think its pretty much identical, but the alloy bolts/cups make the echo lighter.

Moe has just tipped the scales at 275g including the cups and bolts (my bike is in a box in pieces right now so I thought I'd go check :P), thats a good 30g lighter than the Echo's claimed weight. Maybe mine is an anomaly.
