Ultimate vintage MTB shootout Part 2: Mid term progress

I've never written a bike comparison before and for some stupid and diluted reason I thought that taking three similar bikes and comparing them by logging segment times and taking detailed notes would yield a clear winner... yeah right. While I have some interesting data and observations I feel that coming away from this undertaking, as much fun as it is and providing anything more than a subjective opinion will be challenging to say the least. That being said here's where things stand after three rides, one on each bike.



The course:
Living in the mountain bike mecca that is Baltimore, Maryland affords me countless miles of lush singletrack, massive climbs and the kind of techie descents that will throw even the most capable toddler. However, after many hours of riding my local trail systems I've manged to string together a nice ~12.5 mile loop with approximately 1300' of vertical climbing and a pretty good diversity of terrain. It's a loop I now know pretty well and feel that it provides a good setting to evaluate these older bikes. The majority of the course is flowy single track punctuated by a several fast and technical descents with some relatively serious exposure as well as a few punchy and technical climbs. Throw in a sprinkle of rock gardens, stream crossings and some loose climbs and you have a pretty baseline on which to measure most key characteristics of a vintage bike.


Current standings:
Going on nothing but overall course completion time after three runs the Ti Phoenix lies in first place with a time of 1:22:24, in second is the Cunningham with a time of 1:25:56 and pulling up the rear is the steel Phoenix with a time of 1:30:11. Fastest speed honors again go to the Ti Phoenix with a max speed of 30.9 mph (avg 8.5 mph), Cunningham in second with a top speed of 26.8 mph (avg 8.6 mph) and the Phoenix again in third with a top recorded speed of 20.8 mph (avg 8.3 mph).


Data:
Black base line : Ti Phoenix
Purple line : Cunningham
Blue line : Steel Phoenix

Ridge to waterbars : 2.3 miles 8% grade on climb in
Steep climb into the main section followed by a mix of rugged XC style climbs and descents, not much time to rest and lots of opportunities to push all of these bikes. There are several rocky sections going uphill and I only cleared them on the Ti Phoenix.

Chuck Norris climb : 0.9 miles 3% grade
Pretty mellow climb close to the start of the ride, mostly smooth single track that's ripe for attack both seated and standing.

Garrett's DH : 0.9 miles -5% grade
Probably the most fun part of the overall loop, fun and twisty downhill with a few chicanes flanked by fallen trees and featuring upturned rocks and boulders. Can get a bit hairy and definitely helped by some front squish.

Garrett's Pass 2.3 miles
This is XC in a nutshell, couple short climbs followed by flats perfect for an all out push and then leading to a wicked DH I separated out above.

As you can see I was actually ahead on the Cunningham during many of the climbing portions of the ride and it was the descents where the Ti Phoenix pulled away. Of course this is where the suspension fork clearly plays and I have to believe that the two bikes would be neck and neck if the Phoenix had a Type 2 fork. Honestly I don't know why the steel Phoenix isn't measuring up. I feel very confident on it, it's a bit more compliant than the Cunningham and the Schwalbe tires are actually a bit beefier than the Onzas on the other two bikes.

Conclusions thus far:
Hard to really come away from this with a single answer, at least so far. At first I really thought I would be the fastest on the steel Phoenix as I could tell that I was pushing the bike about as hard as I could and rode it the most leading up to starting this challenge. There is no denying that the steel Phoenix is a great bike. Like the others it's very stable, tracks predictably, is easy to handle, has quick handling and is comfortable on longer climbs and rides in general. It's a mix of stiffness between the Cunningham and Ti Phoenix and unlike the other two bikes it's the one where I can really feel the grip the best. The Cunningham is by far the stiffest, believe me or not but my hands and body definitely get tired faster and consequently I'm actively hunting for the smoothest line on all terrain which takes away from my down trail attention. It's probably the best bike for climbing out of the bunch, though that could just be the overall fit of the bike resulting in an optimal climbing position. I did observe that I did the least out of the saddle climbing in this bike and in most circumstances could just power through things. It is however the bike I felt the least comfortable descending on, again maybe due to the fact that it's a slightly taller or larger frame than the other two. But I don't feel like I have a good sense for the traction limits and leaning over hard in cornering has resulted in the front wheel washing out at speed on multiple occasions. The Ti Phoenix is probably best described as the most fun of the bunch. It's easily the most compliant bike, both because of the suspension fork, but also the rear end just feels a bit smoother and doesn't get perturbed easily, meaning I'm less worried about rear wheel placement, unlike the other bikes. Like the steel version it's just so damn predictable, probably even more so that the steel version. This is likely why I've been able to push the it harder than the other two on descents. The best thing about it, and this isn't fair to the other bikes, is the drivetrain and brakes. I absolutely love the way this bike performs, the shifting here is the best by far and the combination of Suntour MD front with an 11-28 Shimano rear end makes for very versatile gearing and really the middle ring is about all I ever use (I get into the granny on the other two). Also the brakes on this bike work better than the other two. The Lever Link up front is a veritable anchor and the Toggle Cam in the rear has the full lock point just dialed in perfectly. I feel like I have the best control of the bike when it matters. Oh yeah, the fork doesn't hurt. I've caught myself wondering on several occasions whether I should get a Type 2 fork made for it... would be neat I think, but not sure I'd chose to keep it long term.

So, three more rides on the same loop to get some more data and see if the trends continue or if things shake up. I also have a few things rattling around in my mind in terms of characteristics I want to focus on for the next rides to try and fill out the overall picture a little bit better. I'm going to give each bike a small tune-up to try and ensure a level playing field and take variables out of the equation. Stay tuned for a wrap up in a week or two.
