[Closed] MTB group on a cross bike

[#10376442]

Cable discs still seem like a compromise but road hydros are too expensive..so I'm thinking of chucking a flat bar and a 1* hydro groupset on my cross bike.
Aesthetics aside, would it all work?
The only sticking point I can think of is shimano chainset on a bb30 but I can probably resolve that with a 24mm adapter.

If you do all that it won't be a cross bike - it'll be a rigid mtb with skinny tyres.

Or a fat bike with really skinny tyres.

MTB thumbies / shifters won't fit a drop bar - drop bar are a bigger diameter - Pauls Components make adaptors though.

What's so bad about cable disks again?

Thanks all. I'm completely aware of the irony here.

Cable discs, nothing terrible I've used them for years but I just find them a bit fiddly (the bike is used mainly as a commuter) and not as powerful as their hydro cousins.

The brakes are due for replacing and I think the chain set will too, so I was looking at upgrading to a hydro groupset, but they are so expensive compared to an MTB groupset.just looking at it as an option really.

I had a flat bar Genesis CDF a while back and it was brilliant fun.

I needed a stem 20mm longer than with drops, and I'd recommend an alt bar like an On One Mary or something. No point have a superwide enduro thing

My commuter has had drops, flats and grandad bars, and amazingly it works really well with all three! I have a 70mm stem with drops, but had 105mm with bars and it had bar ends too.

Well done, you've just made a hybrid.
It'll work, though you may need a longer stem as drop bars make the bike longer.

Just buy some cable hydro brakes like the Juin tech or the Giant set up, not an expensive alternative. Juin techs are pretty good and largely faffless

I’ve had faffy cable discs but my present Spyres are fine. I see the attraction of hydraulic but personally , due to the integrated nature of drop bar controls, I’d leave them alone unless spending enough to go full group. The Juin’s Would probably be the only halfway house I’d look at. No plan to swap my Spyres for them though.

I've got spyres at the moment.

Power is pretty crap, better than my planet x cnc ultralight callipers, but not anywhere near mtb brakes. But they're quiet and stop me without being too scary.

They're a good compromise between cost and performance so far. I was going to go with juintech but reviews seem to suggest the pistons and seals leak.

Keep an eye on ebay. Hope v-twins sometimes go cheap as people are now upgrading to full hydro systems.

As per the earlier post, Giant conduct brakes are a reasonably priced option.

A friend of mine likes them

I'd say TRP Spyre SLC over the Juin Tech. The piston on the back end is forever having problems due to all the crap that's sprayed into it and they never stay "just right", the front has been "OK" but not brilliant. The spyres have been fine however. Couple it with compressionless housing and you're onto a good set up.

People using crap outers can't get them to work properly and blame the brake?

Not sure why I'm justifiying my views in this topic, but here goes..

I didn't say there was anything wrong with cable operated. I use quality outer with in line cable adjusters and with work I can set up my BB5 really well. But when I upgraded to hydro (on my other bike) these provided an increase in power and they are much quicker to set up. So I consider them a compromise.

I wonder how many on here run cable operated discs on their mountain bikes??

I must say the spyre look pretty good as both arms move, unlike the captive arm on avid BBs.
Cheers
