Upgrading a Stumpjumper
Has anybody built a stumpy with big forks and generally strong kit?
I’m thinking about getting a stumpy frame as my Enduro Evo is a bit too much for my mincing. And I want to build it with my Lyriks, full SLX and strong wheels . I think it will be spot on for what I want out of a bike.
So have you beefed up a Stumpjumper?Posted 4 years agostumpy01Member
If the Enduro Evo is too much bike and you are thinking of ‘beefing’ up a Stumpjumper, why not go for a Stumpjumper Evo?
Depending on how much mincing is going on, why not just stick to a normal Stumpjumper. Mine copes with everything my extremely average skills can throw at it!Posted 4 years ago
I’m thinking second hand frame only purchases here so the choice is pretty limited as to what I can get. I think the Stumpy Evo is probably the best thing for me but I don’t know if I can get one.
The Stumpy evo has 150mm forks so I doubt putting my 160mm Lyriks on will make much difference. The Evo also have the same main frame as the normal stumpy but with a different shock and I think rocker.Posted 4 years ago
I run mine with 160mm Pikes (with travel adjust), Easton Havens and so on. 60mm stem (started with a 50 but it was too small) and 785mm bars (which I will one day trim to 760/750). It’s very nice, it’s the Evo version and is very capable. I’ve done a trip to the Pyrenees on it, taken it up big mountains and it’s taken it all in its stride. Previously I would have gone for an Enduro but this is 26lbs and everything downhill just about as well but makes life a lot easier going up and handles “normal” trails a lot better.Posted 4 years ago
Yes, carbon frame with carbon cranks, Havens, Zee shifter and mech, Hans Dampfs, SLR saddle, Race Face Turbine bits and XT brakes.
I got the travel adjust model because I will be using it for XC racing so needed to drop the front. I use it on almost every climb- at 160mm the size large is quite tall (they have massive headtubes) up front and the lower front helps me out.Posted 4 years agoTraceySubscriber
Kevin has a S Works which he ran with Lyriks for a while and then fitted the E160 forks to it. Had 5.1 DT Swiss rims on Hope hubs but now has American Classic AM wheels Rest is XT with some carbon bars. He took it to the Alps last year and loved it so much that he gave Abigale his Enduro. I think he rides the bike better than he did his Enduro. It is light but haven’t weighed it. Had no problems with the longer forks on it

I beefed up my Pitch with 160mm forks and it’s an absolute beast going downhill.
A mate of mine stuck some Totems on his and created trail blazing juggernaut. Looks mean as, too 😀
I picked up my second hand stumpy evo last year. Changed the bars, stem and pedals from the off and then rode it on all manor of trails. The only thing that i felt needed upgrading (bars and that were more a swap) from the stock bike were the forks but since you’ve got some lyrics, you’re covered.Posted 4 years agoTraceySubscriber
No problems with the brain. It does what its supposed to do on the ups and is great on the downhills. If he had thought the Enduro was better for him in the Alps he would have kept it for himself for this years trip. He has a shorter stem in the garage to go from 70mm to 45mm once he gets round to fitting it.Posted 4 years agokudos100Member
I’d go for a stumpy evo if you can find one. The head angle is slacker and the BB is lower.
That said I’m sure the normal stumpy would work well beefed up.
My evo had Flows, 1×10, wider bars, shorter stem and zee brakes. Only thing I would like is a slightly bigger fork. Great for xc rides and also a bit of DH.Posted 4 years ago
anyone interested in something like this. allows you to run any normal shock including CCDB etc. i have an RP2 lined up for my brothers stumpy, just waiting for us to make the adaptor.
the second pic is an example off something else we made.
i get an email every month or so from people asking if i’ve made any but we have been so busy we have not. however, we just cleared the decks and we are looking at a slightly different design which will be a bit easier to make (ie cheaper) and if say 10 plus people wanted one then it would be much cheaper (lots less setup time and programming per part)
the new design will probably look like the lapierre 927 onePosted 4 years agotomasoSubscriber
I ran my Stumpjumper with 160 Lyriks and 150 Revs – both of which were good. Lyriks add a certain unburstable nature to descending and the Revs were very light. 160mm is also not the best for steep technical climbing unless they can be dropped with dual position of u-turn – but thats just me and perhaps what I like to ride.
However, 140mm Marzocchi 44 RC3 Ti were much much better in everyway. Bigger is not always better.
One other mod is to buy an Evo shock as these have shorter length and longer stroke – we are talking a couple of mm – but it makes a difference to travel and geometry with more bounce and slackness. You also get an RP23 instead of a Triad or whatever.
Not sure how strong you mean by strong but Mavic 521s, 10mm bolt up rear, SLX double and dual ply tyres was good for smashing Lakeland terrain. But it is more flexible than bigger bikes like a Pitch.
Oh and it wasn’t really that light at 32-33lbs
I wouldn’t of had a reason to change bikes if it hadn’t been nicked…Posted 4 years agoRickosMember
