Re: Aftermarket Disc Brake pads

Thanks Brucey, some interesting information there. Have to say I was confused by the Shimano disc rotors I've fitted saying 'resin pads only' but looking at the OE Shimano pads they clearly contain bits of coppery-looking material, so seem to be semi-metallic. I naively assumed 'resin' meant 'organi...

Re: Freehub lubricant?

I just fill my freehub with the same grease I use in the wheel bearings, by removing the rear seal of the freehub body and forcing the grease through by hand while rotating the bearings (I use Silkolene Pro RG2 motorcycle bearing grease, cheaper than cycle-specific greases). It's a little thick to b...

Re: Specific Fixed gear chainring will I notice the difference?

Spa cycles do decent quality 'zicral' (7075 ali) chainrings in 110PCD for sensible money. The teeth on mine all appear to be full height. Obviously thinner than a 1/8"-chain-specific 'ring but given the apparently poor quality of common 1/8" chains perhaps you'd be better running a 3/32&qu...

Re: 32 spokes v. 36 spokes - Ride Comfort?

Hi, I hope you don't have a stack of PC830 chains; they are the cheapest chain that SRAM make and they lack proper hardening on the pins. Even with good lube they wear out in ~500-1000miles. cheers Is this typical of sram pc830, Bad batch? Brucey's comment is relevant I think. certainly appears the...

Re: 32 spokes v. 36 spokes - Ride Comfort?

I'd suggest it's irrelevant. What? 32 vs 36 ..... or ....... 8 vs 64? Same rims, different drillings. Hey, we think along similar lines :wink: Though I found out today I'm suffering from chain stretch :shock: . Only done 499.30 miles since 15 December on a Sram PG830 chain and found out today, that...

Re: Rims with decent braking surface thickness?

is the soil especially abrasive where you are? Or is it very hilly? The wear rate of your rims seems a fair bit higher than average....? cheers Don't know, based in South Somerset, but my commuting bike tends to stay cleaner than my weekend bike as it will be cleaned at shorter distance intervals (...

Re: Rims with decent braking surface thickness?

Can only say that weight doesn't necessarily seem to correlate well with braking surface thickness. The Kinlin XM250s I returned measured around 1.3mm thickness and weighed around 480g. The Exal LX17 (also 17mm internal width) has a specified eight of 575g but also measures down to 1.3mm in places, ...

Re: Rims with decent braking surface thickness?

Not wanting to be ignorant, but I switched to a front disc brake on my commuting bike about a year ago to reduce maintenance as I was getting cheesed off with constant cleaning of rims and brake pads (the latter to remove embedded debris) and so far I'm very happy with my hydraulic front brake. I ch...

Re: Rims with decent braking surface thickness?

Well, to complete this thread, my newly-ordered H Plus Son Archetype rims arrived last Friday and were duly measured. Braking surface thickness turns out to be ~1.5mm on one side and ~1.3mm on the other, again (badly?) machined sidewalls, despite costing twice as much as the rims previously used (E...

Re: Rims with decent braking surface thickness?

It's not the answer you want, but it might be the answer you need - why not drum brakes? Bypasses all the problems with rim thickness and rebuilding rims. It is a winter bike after all and you say you are slowing down to match the local group you ride with anyway. Yes, they are heavier, but the wei...

Re: Why the sudden urge to ride bikes on gravel?

Funny when I bought my Dawes Mean Street 25 years ago it was marketed as an off-road variant of the Galaxy, using same 531ST frameset but with unicrown forks, fine knobbly tyres, Deore LX MTB groupset and very strong Alesa 917 rims. Does this mean I was 25 years ahead of the curve? :lol: Ironically ...

Re: Why the sudden urge to ride bikes on gravel?

It's just a label, but anything that produces road bikes better suited to the crappy road surfaces and weather we 'enjoy' in the UK, and more opportunity to escape the oppressive traffic by going light offroading, seems like a great idea to me. i.e: Disc brakes freeing up good tyre and mudguard clea...

Re: Rims with decent braking surface thickness?

Salmon's the colour, Kool Stop the make. Great pads for normal rims too - best I've found so far for not embedding grit and aluminium particles.

Re: Rims with decent braking surface thickness?

FWIW the unworn Exal LX17 on the front of my disc-braked commuter measures around 1.3-1.5mm. Maybe the SP19 is similar?
