Rated 3.8 out of 5 by 33 reviewers.
Rated 2 out of 5 by At least CRC has a good price I purchased a new bike with a Powerspline crankset once and it was replaced within 100Km because it was creaking. The benefits to the non-square spline BB's (ISIS, Octalink, Powerspline) do not outweigh the cons. The bearings are simply not large enough to support the forces generated by the cranks. Stay with square taper or move up to external bearings. Kudos to CRC for at least selling these at a decent price 01 August 2014
Rated 5 out of 5 by So good I bought another.. A certain high street store was after 29.99 for this. Thanks To CRC I got this, a spare and a trip to the pub for the same money! Easy fit to a Carerra Kraken, last one did nearly 5k before it got the creaks lets hope this does the same but got a spare just in case they go out of production. 12 May 2014
Rated 3 out of 5 Not the BEST i did give it abuse going off 40-50 ft (homemade) drops which didn't have the smoothest of landings. then realising that it was rattling and loose. after taking it off i read on it "for cross-country use only not for downhill or jump bikes". and being a cheap skate i carried on using it till i cased a gap and it's completely useless, but for the price it is probably worth the 4-5 months you can get from them. 05 April 2014
Rated 5 out of 5 by getting harder to find getting a bit rarer these bottom brackets, not many bikes coming in with these fitted , nice to know they're still available at a half decent price 21 March 2014
Rated 5 out of 5 by Excellent bit of kit Despite some of the horror stories of power spline mine lasted 2 years of general abuse and neglect Given im a hefty unit and put a lot of strain on the cranks I think 2 years is fair for replacement :) 03 March 2014
Rated 5 out of 5 by Works as it should Not a lot to add to previous reviews, was straight forward to fit and has lasted well. No issues with creaking and has been running through the last 3 months on my Hybrid commuter. Would have no issues replacing with this again when required 14 January 2014
Rated 5 out of 5 by Great reliable bottom bracket for the average rider I don't understand why some reviewers have got so little mileage out of these BBs (variations in manufacturing quality?) or complain about value. Speaking personally, I have got through three of these now over an eight year period of fairly heavy lake district MTB use, so no complaints. I 'upgraded' one of my bikes recently to a Shimano hollowtech system but I wish I hadn't bothered! Admittedly it was only a budget BB51, but it failed after about four months riding and I didn't notice any difference in performance or power transmission over and above powerspline. Some reviewers baulk at the cost of powerspline, but do the maths: Replacing powerspline BBs (bought via CRC) has cost me, on average, about £20 a year. Replacing hollowtech BB's at current wear rate will cost me an estimated £35 a year (and the tools are more expensive) . Have just bought a hope 'hollowtech' BB (yet to be fitted), but even assuming I get three years out of the stainless bearings they will still cost me an average of at least £10 a year, plus the cost of bearing tools/workshop fees. On this basis powerspline gives fair value for money and is way more durable than bottom end hollowtech. 07 January 2014
Rated 4 out of 5 by good vaule for money Overall not a bad product doesnt last as long as i would expect from a bb but for the price no big deal. Easy to fit takes about 20 mins but still not big fan of this powerspline set up as there is better bb out there for same or cheaper. 18 December 2013

Answer: 
Both the 68mm and 73mm wide spaced bottom brackets are BSA English Threaded.

To determine which size is required; measure the width of the bottom bracket shell on the bike that it is intended for.

A similar principle applies to the spindle length; which should be measured from the existing spindle being used.

If this bottom bracket is to be used with a new crankset and chainline is a concern; please contact our Technical Department below:

Answer: 
The Truvativ Ruktion chainset runs the Howitzer bottom bracket interface, so this Powerspline bracket is not suitable. You will need a Howitzer bracket such as those listed below.

Answer: 
This bottom bracket will fit to the frame fine; however it may not have the correct engagement on the spindle for the crankset supplied with the bike.

Please provide more information on the bike to our Technical Department below -

Answers

Answer: 
No; Powerspline is a proprietary Truavativ bottom bracket design and is only compatible with Powerspline specific chainsets. The ISIS Husselfelt requires a 113mm axle for a 48.5mm chainline or a 118mm axle for a 51mm chainline. If unsure which you need, simply measure the axle length on your previous bracket (image below).

Answers

Answer: 
I am not aware of any Powerspline BB that is not built around the ISO standard so you should be fine. If you can, pull the Powerspline cartridge and make sure that the cartridge is ISO standard (ie: 68mm x something or 73mm x something) and there should be no problems with installing a new Hollowtech BB. Just make sure to get your bracket threads faced and chased to minimize bearing wear and creaking problems.
