My lugged '92 Trek 930 with first design Origin8 Gary Bar and Terry stem. The silver sleeve on the top tube is to protect the top tube from the handlebars.

I vaguely remember something about a collaboration between Tom Ritchey for the first mtb frames from Cinelli, but i'm not able to recall the details. Cinelli made frame for some other, in particular for austrian kastle (kastle randonee in particular). This is a first series 8001, the second series had rear cantilever brake [EDIT they were ubrake probably] on the seatstays...

1994 Specialized Hardrock Sport

I just finished this drop bar conversion . . . although maybe not technically a conversion because it didn't have any kind of bar when I got it. But it originally had a flat bar, so here we are. I found the frame in my local community bike shop. It came with the fork, headset, bottom bracket, seat post, seat (which I didn't use) and brake calipers. The paint, bearings, and components were all in great shape, so I think this bike may have lived most of its life in the corner of a garage. Other than that, the goal of the build was, as much as possible, to use parts I had on hand or that I could find used in community bike shops. I powder-coated several of the used components silver so the bike wouldn't look like Johnny Cash's Cadillac. The only things I bought new for it were the ADVENT X brifter set, cable housings, the chain ring, bottle cages, and bar tape.

Hi,
Is that a front bike rack that doesn't require a side stud on the fork? What is the make and model?

Or the Cinelli road frames from 50's through the 70's?

They were doing it long before most others.

Trek 800 sport


I think it is a 1996 or 97 trek 800 sport. 16.5inch frame. 3x8 Microshift brifters. It was a curb find. With a combination of parts bin, co-op and new parts I have $165 in it. My 11 year old son likes it

Since I built my Aerotek 4000 eight years ago, I've worn out two rear rims, two front rims, one Shimano dynohub, a set each of aero levers and cross levers, six chains, and four cassettes. If my shifting were indexed I'd probably have had to replace the chain and cassette more often. Over the last few months I've redone the cockpit with new levers and built a new front wheel with a SON dynohub and DT Swiss Alpine III spokes. Here's the bike this morning.

It's hard to see what's going on, but did you use an old chain ring to make a headlamp mount?

Yup! I was inspired by an old rivendell blog post that I can't find now. Found out that simworks is now selling chunks of chainring for this purpose though, $18 a pop!

Logan Kaspers drop bar mountain bike

I'm sure someone has said this somewhere in the forum at large already, but did any other drop bar conversion fans in this thread notice that Logan Kasper's winning bike at Unbound was a drop bar converted mountain bike? Clearly not vintage but definitely a mountain bike with drop bars.

When the gravel gets tough, the tough get a drop bar mountain bike conversion.

I predict that the next big market category will be monster-gravel, which will basically be 29er hard-tails with shallow dirt drops designed and optimized to handle actual, not idealized, dirt road conditions. Maybe 26 inch will even come back because Specialized will realize that you can get even more mud clearance by using 26 inch wheels. They will then claim to have invented the 26-inch wheeled bike.

I have already contacted an Alibaba source and put a down payment on 5000 copies of Logan's bike .

Can we get pictures? I always wondered if anyone considers doing these races on a drop bar conversion or even straight bar using 26" wheels. I mean, they did mtn. bike races on these things 30 years ago so I think they can handle it.

I would think you would have advantage on any of the dirt or technical part of the route but would have to hustle really hard on the road to catch up on any of the road sections. If anyone has any experience or knows videos or stories I would love to see more.

I have been looking for good photos, but the best i have found is at 40ish seconds here


And there is a quick mention on the reneherse blog about the clearance afforded by Kasper's mountain bike. That's what sent me looking around.

I agree with your assessment in general, but think that the mud hill was basically a random trial, essentially there was no predicting who would get through regardless of skill. From my (very limited) experience in other races, those in front (the better riders) were actually at a disadvantage because those behind (me and my fellow weaker riders) learned of the issue (I still totally lost the race). This effect would be harder to see in Unbound because of the strict segregation of non paying pro riders and paying amateur riders. There might not have been an overall learning effect among the riders. But that's another can o worms.

So a hash assessment of his victory would be: a bad section randomly eliminated the best. His equipment allowed him to get through that part, which literally ripped the derailleurs off of other bikes, regardless of who was riding them. Then there was no one left who could keep up with him, even if his equipment was less efficient.

But i don't know enough about the route. There could have been other places where his equipment was an advantage and that scratched other contenders. It could also be that the "inefficiency" of a modern 29er with no mud issues because of clearance and with a locked out fork is overestimated in relationship to a gravel bike caked with mud.

I don't know if anyone has really tested this. I know wilcox has run suspension when others haven't, to winning success. Sahili runs a mountain bike while others run gravel bikes and consistently wins, but he also doesn't seem to need to sleep. On the other hand, king just ran a mountain bike on the divide and scratched. Who knows?

But as an aside, this is why the UCI has tech rules--to try to control for equipment advantage and isolate rider performance. So maybe everyone on Unbound 2024 should be required to use a regulation cyclocross bike. But that's against the ravel ethos, i guess. But certainly fun to watch!
​​​​​
The other explanation is Kasper was just the best in the field. That is also an explanation.

My post was mostly make fun of the return of our favorite bikes

Your other point, about 26" wheels:

Question, I might be acquiring a Specialized Rock Hopper from a friend and I would like to do this right with a 1X drive train, nice comfy handlebars, big gum wall tires and maybe a pizza rack, we'll see. Where do I find the group set at a reasonable cost?

Shop 'til you drop. Check amazon, ebay, the seller's forum here etc.
