Thoughts on a front disc on a 'Crosser
I find the BB7 Roads on my CX bike don’t seem to set up quite as well (in terms of rub vs bite point tradeoff) as my various MTN versions always have. Also, the inboard adjuster wheels are absolute bastards to turn without gloves on. Having sworn by BB7s for over a decade I was a bit disappointed. They work fine and the issues aren’t showstoppers; I’d just be tempted to try others as well.Posted 4 years agopistonbrokeMember
I’m building up a carbon framed cyclo-cross frame which has a disc mount on the front fork but canti mounts on the rear. I’ve looked at fitting a cable actuated disc on the front and options are Avid BB7, TRP Spyre or TRP HYRD. Before I jump, what are opinions on these or other options? I’ve fitted many Avid calipers and found them fiddly with the 1 sided actuation and them virtually rubbing on the opposing pad to get any lever feel. Not had any experience of the TRP ones so would be keen to hear if they are any better.Posted 4 years ago
I think that these issues are part and parcel of only one pad moving as in all, up to now, cable discs. At least the BB7 is easy to adjust. within weeks I had the pistons out of mine for a touch of copper grease.Posted 4 years ago
Maybe the Spyre is the next step although reviews I have read suggest that its no more powerful than the BB7. I suppose it may be sweeter though.
What ever , don’t waste you brain cells on the Tektro Lyras.spangelsaregreatMember
Used BB7 for years and they are good. Changed to Spyres a month ago.
I would go for a Spyre if you are buying new. They are not any more powerful than the BB7 but are better designed and lighter. Having both pads move does make adjustment easier (not that BB7 are difficult). They have a slightly thinner so look nicer too.

I’ve got Shimano CX75 on the Fargo, like most other things Shimano, they just work. Seem to need every different size hex key in the box to install and adjust though, but not an issue unless adjusting mid ride, but they’re Shimano so they don’t need that often. There is a recall going on and I’m going to get some new CX77 as replacements, I don’t know the exact issue though. Something to do with ham fisted adjusting I think.Posted 4 years agocpSubscriber
I use BB5’s. Apart from fiddly pad replacement, I find them great – rub free and powerful enough for road and CX. They’re a big lump though, I’ve not weighed them but they must be fairly weighty!
Only siginificant upgrade IME would be to a full hydraulic system… some way off!Posted 4 years ago
