I've recently purchased some BB7 calipers for a Flux Beta bike which will be used for commute style purposes. It will travel large distances frequently and maintenance and the cost of that maintenance is important. They are to be paired with fresh, uninterrupted cables and new BB5 levers.
I'm trying to choose rotors to match with them. I was thinking 200mm front and 180mm rear. The obvious answer is Sram G2 Cleansweep rotors as I understand they have a larger brake track and are designed to be used with these brakes. However, it appears SRAM has cut online retailers from selling SRAM to Australia (particularly CRC and Wiggle). This is an unfortunate trend which I think will continue. I have noticed Rockshox shock mount hardware recently disappear from CRC, which I assume, is for the same reason.
The original plan was to have genuine consumables (pads, rotors etc) to be purchased from sites like this to maintain quality components but keep the costs down. However, that no longer appears to be an option. I could arrange a redirection service, but it's more work and I'd rather not if I can avoid it. At this time, I'm trying to identify alternatives which would work as well as the SRAM genuine item, for preferably the same, or lessor cost.
There are many on ebay, but from searching other forums, it appears they are not usually genuine SRAM and are usually considered inferior. The discussion there usually is about determining whether the items were bulk purchased and therefore genuine and/or disputing that by various ways of identifying the genuine version.
It's left me wondering a few things:
- is it worth trying to buy genuine SRAM rotors? I've always replaced genuine with genuine previously, but I'm curious to find out how bad the non genuine really are? Or is it that there is no standard and its luck of the draw as to their quality? Are rotors difficult to manufacture well?
- is there a Shimano equivalent 6 bolt rotor? I note there is differences in Shimano/Sram disc sizing (200mm vs 203mm) yet others on the internet allege they have used Shimano rotors just fine? This could offer an alternative supply of quality rotors which can be bought from CRC/Wiggle etc. Ideally these need to have the same larger style track which the G2 has. Is there anything else I should be trying to check first?
- what pads are recommended? I imagine there are many different types out, but the trade off between price and quality is difficult given I need to be careful the costs don't blow out in the long run.
- any other advice in relation to these brakes. Its the first time I've used mechanical discs and they seem pretty simple. Others have recommended >200mm discs to increase the braking power, but I doubt the alloy fork mounts would be tested that kind of force and this isn't something I'm considering at this stage. I would be more incline to go for a better or more effective pad at this stage, but thats just a musing/opinion without experience or support.
- Is 200mm front and 180mm rear ideal or should I go 200mm front and rear?
