anyone try these? supposedly bontrager branded track cranks.
i'm trying to decide if the outboard bearing BB is worth upgrading to for my Rob roy

edw

Their website says "TruVativ made this crank for a another manufacturer who's logo is still on the crank. " I maybe mistaken but those cranks come on a lot of entry level complete bikes. You may be better off trying to find some one who is upgrading and has one laying around.

I haven't seen outboard bearing cranks on any entry level completes yet....

edw

apparently i am mistaken

I was wondering the same thing here. I wish they had better photos...
You can't tell **** from that Bikeman photo

The LT

Truvativ makes the touros which come on many entry level bikes and look similar to those with the exception of the outboard BB. I wonder if these are maybe something truvativ is moving towards to replace the touros

track crank


touro crank

SeanBonham

no option for chainring on outside?

I don't see a crank like this anywhere in the TruVativ lineup. It's certainly not their outboard bearing track cranks, the Omnium. I think these are a little suspicious.

The LT

ya they don't necessarily have to be in the truvativ lineup as they are OEM products made for a different company. I wouldn't be surprised to see these come out soon as a replacement for the touros though

Outboard bearing cranks - soon to be obsolete technology. And rightfully so. Long live square taper!

trons

is it so crazy to think they are telling you the right info? looks like these...

that was the bike i was assuming they were off of.
well, just placed the order, so i'll let you all know how they are.

At that price for the crank and cups it may be worth a try. I have had good luck with bikeman in the past.

The LT

definitely looks like the ones off the trek

$80 for the crank and bearings is a really good price. With an Origin8 and Sugino bottom bracket you're looking at $80, with an Andel instead you're over $100.

what's the appeal of the outboard bearing? is it just lighter and stiffer?

Aeroplane

Lighter and stiffer than square-taper, longer lasting than an ISIS or Octalink.

They're sourced from Lemond Fillmores. It appears they are 3/32" rings. The BCD is most likely 130 NOT 144. It is essentially the GXP version of the Touro singlespeed cranks. Nice still at $80. I picked up a set too. A TA ring in 1/8" for the set still puts them under the $250 mark Benscycle wants for the Omniums. Hell, I may just leave the 44t on and run a smaller rear cog...

bward1028

only problem for me is that i had to look kind of hard for 22t freewheel at a decent price, so i can run singlespeed offroad and not kill myself walking

captsven

I assume these are 68mm?

Not a lot of info on these...

stewardmike03

Yep, english thread...the bearings will fit a 73mm shell too...but the crank spindle is set for a 68mm shell.

What kind of tool do you need to install the cups? Can they be hand tightened? Will my Hozan work?

bward1028

edit: this one's probably better:

since it's got the name of the BB on it.

blickblocks

It looks like the Hozan bottom bracket lockring tool could bite.
