Is this a stop right there moment?

Has anyone tried using a mountain bike with very slack geometry for a gravel grinder. I did a quick test ride with no brakes on asphalt and the bike feels pretty odd. Don't know if I want to go to the trouble of putting brakes and cables on if it isn't going to workout. Might try a shorter fork to bring the headtube angle back some.

Why not flat bars so you don't have that Johnny racer look and feel.

I've done the flat bar thing. The theory behind this is supposed to be getting some weight off the sit bones and more onto the hands, supposed to be more comfortable riding position for longer time in the saddle and more efficient pedaling. I can't tell you if that's all BS but that's the theory.

You know, with your back, flat bars may be just the thing.

Donut King said...

really? I thought getting more weight of my back and onto my hands would help?

I have tried drops on my KM and liked the geo of my cross bike better. KM was fun just didn't feel responsive enough for the drops. I spend a lot of time on my cross and have a disc issue on my back and the first few rides after a break on it my back kills me. Just some thoughts. I think Larry C put drops on his Indy fab for a while, not sure how he liked it.

I put a Salsa Woodchipper-type drop bar on my IF. Have only ridden it off-road once, and it's gonna take me a while to learn to get over logs with that bar. Been using it around town and it feels like a totally different ride to me. Not loving it so far, but I guess if I built it up for gravel grinds, I need to try some of that before giving up on it.

Ok my initial findings are, the bike feels much better the faster you go, at slow speed it feels odd cornering, Izzy suggested a shorter stem and I agree.
I also agree with Larry, I've got to do some actual gravel riding before making many more decisions.
My next issue is brakes. I bought the BB7 road calipers for this bike but they feel weak. I know the obvious answer is I'm too fat, but I run MTB BB7's on my fat tire and have no issues. Does anyone else use these brakes , and what size rotor are you running. I know Sue uses them but I'm about twice the size of her.

DaveR said...

I think the only difference between bb7 road and mountain is roads are made to work with drop/road levers and take more pull length. So once they "bed in" I would think you would be good as BB7 mountain.

DaveR said...

Retract what I said. I am backwards, as most know. The cable pull thing is backwards. Mountain is longer. Oops.

I have the road BB7 on my crossbike. 160mm front and 140mm rear. Im pretty happy how they perform. Took me a while getting used to the braking power because all my other experience with disk brakes have been hydraulic so as we all know the feel is much different, but overall happy. I have considered going with a 160mm rear as I am a 200+ guy also.

RJ said...

I would agree with shortening the stem. Maybe your alittle to stretched out with your current setup. Get that cockpit alittle tighter and Im sure handling and comfort will improve.

RJ said...

I go back and forth between my crossbike and my carbon hardtail with a rigid fork for gravel grinding and honestly I think my weapon of choice this season is my hardtail set up rigid. I raced the cross bike at Hilly Billy and Three Peaks last year and the descents were sketchy on my cross, but I have much more confidence on my MTB especially descending after I get fatigued.

Donut King said...

thanks to all who replied, good info.

I have BB7 on the cross bike right now and I like them so far. They aren't as nice as hydros but they are still effective. Granted, my cross bike is pretty light though.

Donut King said...

100mm stem to a 65mm made all the difference. Feels like a completely different bike. And I think the brakes are coming around, still not great but adequate.
