Jeff Lenosky - Year 20 Bike Check

by Danielle Baker  
2015 is my 20th year riding professionally. It s been a long adventurous journey and it s still a thrill each time I build up a new bike. Recently I got my new Giant STP and figured a trip to California to avoid the cold weather back east would be the perfect way to break it in. Trials-ish bikes are pretty obscure these days and I get asked lots of questions about my bike when I m out doing trials demos. I m really stoked on how this bike came out so here s a breakdown of what makes my bike unique.


JEFF LENOSKY: YEAR TWENTY BIKE CHECK


This is my 20th year riding professionally. It’s been a long adventurous journey and it’s still a thrill each time I build up a new bike. Recently I got my new Giant STP and figured a trip to California to avoid the cold weather back east would be the perfect way to break it in. Trials-ish bikes are pretty obscure these days and I get asked lots of questions about my bike when I’m out doing trials demos. I’m really stoked on how this bike came out so here’s a breakdown of what makes my bike unique:

FRAME: Giant STP Size Large
FORK: X-Fusion Slant 34 mm stantions
STEM: Pro Components Koryak 70mm reach
HANDLEBARS: Pro Components Atherton 50mm rise full width
GRIPS: Ergon GE 1
HEADSET: Giant sealed bearing with tall spacer and carbon top cap
SEATPOST: Pro Components Koryak cut down to 100mm long
SEAT: Ergon SME3 Black cro-mo rails
CRANKS: Shimano Saint with custom bash ring and 22t chainring
PEDALS: Shimano Saint
WHEELS: Mavic Crossmax XL
TIRES: Maxxis Holy Roller
REAR COG: 17t aluminum
BRAKES: Shimano Zee front 180mm rotor and rear 160mm

Jeff s STP
I choose to run Zee Brakes because they feel really stiff when you squeeze them hard. Trials is demanding on brakes normally on a dirt trail after a certain point a tire will skid when you ride trials you could be jumping 8-12 feet landing with your brakes completely locked.

I get comments from my buddies who dirt jump and ride street about the length of my stem. Trials is all about leverage so a long stem really helps 70mm is actually short compared to what other riders use but I like to keep my bike versatile so it seems like a happy medium.

I had to dig deep for some older Shimano Saint cranks since the new version no longer accepts a small chain ring. I use a 22 tooth in the front with a bash ring to protect it. Somewhere along the line I lost a chain ring bolt on one of my old bikes so now I build my new ones with only 2 bolts on purpose.

Gearing is really important. The general rule of thumb is that a half of a pedal stroke should move your bike one bike length. I choose to run 22 teeth in the front 17 in the rear. This gives you a good amount of torque when you re doing moves from a stand still and let s you time out pedal strokes for gaps and drops when you have a short runway and need to squeeze in as many revolutions as you can. The chainstays on the STP are adjustable from sub 16 to sub 17 . I run them at to make the bike as nimble on the back wheel as possible.

I run Mavic Crossmax XL wheels on several of my bikes and they do a great job for everything from trail riding to trials. The free hub has quick engagement and has been super reliable.

 the only reason I can't ride like him is because he has a carbon fiber headset top cap. equipment these days is insane.

 I measured it off the photo. If that is a standard 4mm allen bolt, the head is 8,4mm in diameter. The axle should sit roughly at about 10mm in. I'll try this and if I can drop a 360 off a 4m ledge, it's legit!

 Thanks for all of the inspiration over the years Jeff. It was great watching you compete in Trials and that got me stoked to get into observed/urban. I remember practising my bunny hops in my driveway for hours and hours on a high jump bar. It had all of the great bunny hop and side hop records on it including yours. Pretty stoked to see such longevity in your career!

 Rad lookin' bike. Aside from killer style & hugely progressive riding, one of the main things I always loved about JL & RL is that they both rocked REAL MTB's. It's a killer HT with a low gear. None of this fvcking dorked up, goofed out 200 mm stems w/flat bars & no seat bullshit. You could ride that bike anywhere. Respec.

Wish there was a video.

 Jeff is the only person I have ever seen bunny hop a 3' log, on a 29er, with his seatpost all the way up. I still cant figure out how he does it. Jeff- if you ever taught trials classes, I for sure take one.

 Should be really nice to see all his bikes through the years!

 As soon as the Crossmax and Holy Roller appeared, he has been running that set up since day 1. Basically his frame has changed over the years, but wheels have stayed Smile
  • 2 0
 Frame only changed when Giant let him design the STP frame. Before that he rode some Giant XC frame in a small size. The STP has changed over years, allthough the geometry seems to have stayed pretty much the same as in the first version.

 Thats definitely not a dirt jump bike anymore. With that build it's much more a street trails bike! Looooooks rad!

 May I ask what chain you are riding? Wondering which 'non-beefy-designed' chain it is, that is strong enough for you to decide to ride on your bike.

 A longer stem is good for trail riding for some of the same reasons it is good for his bike.

 How long are the cranks?
How much travel on the fork?
  • 9 0
 The cranks are 165mm long. The fork is set at 100mm although I run it really stiff so it's more for ride height then travel.

 Yup, you probably know better than the pro that owns/rides it. Ever check him in a trials comp? I didn't ask him why he way riding a DJer and crushing..

 I don't ride hard core trials so the suspension fork works for the way I like to ride, it's not for every style.

 Yeah I get that buddy.. 'Old' ones. Hence me saying he can't find new ones. You read the caption it seems.

 ...meaning the newer Saint cranks don't accept smaller rings.

flag tobiusmaximum (Jun 9, 2015 at 2:26) (Below Threshold)
 Not sure what part of this people don't get, think kazyamamura gets it. The caption clearly says older Saint cranks. Why sponsor a rider in a discipline if they clearly think it's so pointless they don't even make a crank he can use? Maybe I should've expanded the point. Thought it was pretty obvious really.. He's a pro, check. He uses new gear... No check?! All I'm saying is shimano obviously think trials is dead.
  • 3 1
 Read and comprehend. The 'old ones' in the pic look nearly brand new.

 Not sure what point you're making. Fresh out a box or otherwise, a pro having to use out of date gear kinda diminishes the very point of a pro. It's a clear fail from shimano in my book.

 Sorry if my original post was misleading, just feels a bit like they're saying 'here's Jeff, so prolific he's been sponsored longer than some of you have been alive, but say goodbye to trials, it doesn't generate enough revenue'.

 @tobiusmaximum They're just cranksets man. Shimano as a company does wise business decisions, why would they spend so much R&D to produce a crankset that they know would probably not sell well due to the fact that there already millions of variants of similar cranksets. Chris Akrigg uses an XT crankset on his trial bike so why waste time develop another crankset that's probably the same.

 This is a little strange. Who cares about the new old stock cranks. Clearly he doesn't. It's a good crank.....
  • 3 0
 Just having the name Saint showing on the Crank is sufficient for product placement. It doesn't matter if is an old or new standard...the brand is being marketed. No illuminati conspiracy behind.
  • 1 3
 R and D? For a product that already existed? It's four bolt holes basically.
And how is the brand enough for product placement when the product doesn't exist anymore? Brand placement is different to product placement as the name suggests.

 Those cranks really have you torn up! As a trials rider I can say that trials might not be dead..... but it's definitely one of the smallest segments of cycling. The reason I run Saint Cranks and every other component I chose is because I want my bike bomb proof. I throw this bike in a duffle bag and travel all the time and I don't want to run anything that could possibly ever break or bend when I'm on the road. I weigh 215 pounds so there's definitely lighter stems, bars, forks and cranks but I like this stuff. Other riders sponsored by Shimano run XT or XTR cranks so that's always an option. The reason Shimano and other companies sponsor me is for the general exposure I provide. I love riding trials but I really like to use it as a tool to get people psyched on bikes. Most of the demos I do are just to provide entertainment and motivate people to ride and have fun. 99.9 percent of the people who watch will never go ride trials but hopefully they dust off their old bike or buy a new one and when they do maybe they'll consider the brands who support me. Make any sense?
