Re: Hollowtech crank failure - cause ?

Thanks for all the contributions and preventative suggestions which I shall carefully consider. Given the further speculation surrounding the failure, just to provide a bit more context. I'm not a Pro or 1st Cat (although naturally I consider myself powerful :D ) My riding style (especially uphill) ...

Re: Hollowtech crank failure - cause ?

Thanks for the response and analysis. Looking more closely there is indeed some evidence of non recent rust. Funnily enough out on my bike today (with replacement chainset) the slight creak from my left shoe plate has disappeared, leading me to conclude that it was not the shoe plate after all! That...

Hollowtech crank failure - cause ?

Had a bit of a mechanical on my last ride ... Item was a Dura Ace 7950 hollowtech chainset (purchased circa 2012) fitted into a modern bespoke 853 steel frame. No early indication (at least that I noticed) of potential failure. Indeed I have only recently refitted crankset about a month ago. Bottom ...

Re: 2017 Rim recommendations?

Thanks for all the helpful suggestions. I am tending towards better the devil you know and the Open Pro's once again. A friend has recommended Open Pro ceramic, but his rims are quite old (they last forever allegedly). Looking on the Mavic site they have something called Open Pro CD. However reading...

Re: Yet another creaking sound

- Removed crankset. Noise still there, so it isn't the chainring bolts either then Little bit confused by this (I am easily confused!) Do you mean you removed the crankset and noise was still there or that you removed crankset, tested bolts and noise was still there once reattached Only reason I as...

2017 Rim recommendations?

Hello, I am currently using Mavic Open Pro 700c rims (clincher). As with most components these days, despite minimal use in the wet, they do not appear to be as robust nor as long lasting as I fondly recall rims from the "old days" and it's time for me to consider their replacement. I am i...

Ultegra 6750 chainring compatable with DA 7950 ?

I have a problem with the large chainring on my Shimano DA 7950 chainset (50 teeth), namely one of the treads appears to have stripped. Whilst the bolt will bite to a degree it is not possible to firmly secure it and the chainset (assuming its not my knees!) ominously creaks when running on the inne...

Thought I would add an update to advise that my order for the Dura Ace jockey wheels (at an expensive £30 pair) fell through :-( The only other alternative sources have increaed in price to a truly eye watering £40 (you would think they were gold plated at this price!) I took Gattonero's advise and ...

Re: Dura Ace 7900 rear mech - jockey wheel

Brucey,

Thanks for the super swift response.

Not sure where I got that Shimano part number from, as I was looking at the same tech document as you.

I have managed to locate a set via Amazon for £29.99 (which I presume was their normal price before inflation/devaluation struck).

Cheers

Alan

Dura Ace 7900 rear mech - jockey wheel

Learned Bretheren, Much to my surprise (is it just me or do modern components seems to wear out faster these days ?) the jockey wheels on my 7900 rear mech appear to be shrinking at an alarming rate. Poking around on the Shimano website suggests I need a "tension and guide pulley set" (ref...

The Cycling Lawyer comments on recent judgements.

Small claims court - damage limit changes (bad news)

There has been some quite lively debate this week on this forum about a legal judgement concerning a Time Trialling cyclist's damages being reduced by 20% owing to deemed contributory negligence on his part. Well here comes another "corker" that is more likely to affect the average cyclist...

Time triallist 20% to blame for accident

Spotted this High Court judgement http://www.bailii.org/ew/cases/EWHC/QB/2017/264.html on the Baili site, holding that a time triallist was 20% to blame for his (life changing) injuries caused by a driver negligently turning across in front of him. As a biased cyclist, I must confess that this finan...

Re: The rights of motorists

I think it would send out a better message if the police and media used the phrase "driver lost control of their vehicle" rather than "vehicle went out of control" to show exactly who messed up. On a similar theme, I am always infuriated when Press reports of cycle/vehicle incid...
