Slik får du Bluto på Salsa-fatbiken din

Fatbike med demper har blitt en selvfølge fra produsentene. Men hva med oss som ikke vil tømme lommeboka for en ny sykkel?

Introduksjonen av RockShox Bluto dempergaffel til fatbike satte i gang økt hjerneaktivitet og våte dagdrømmer hos flere enn bare oss, og det er bare å innse at fatbike med demper er kommet for å bli. Men hva med oss som allerede har investert i en fatbike - uten demper? Vi tok en prat med sykkelhodene ved Salsas eget hovedkontor, for å finne ut hva som skal til for å gjøre drømmen om Bluto til virkelighet for de som har eldre Salsa-modeller.

- Koster å være i front
Først av alt takker Salsa-teamet for at de har fått mulighet til å sitte i frontsetet på denne utviklingsreisen, men påpeker at å være i front også er ganske risikabelt.
- New ideas and designs change and evolve quickly. What was the "standard" today can be obsolete tomorrow. Fatbikes are no exception, but the good news is Bluto works on a large majority of Salsa fatbikes sold to date. Note: The 120mm Bluto is not listed because all Salsa fatbike frames are designed around a sagged 100mm fork length.  Using a fork longer than this length is something Salsa cannot endorse, as we do not have the documentation surrounding it. Please note that doing so also voids the frame warranty.

Ikke for alle
Dessverre er det slik at ikke alle sykler kan tilpasses Bluto. Følgende sykler er ikke kompatible, dvs. at det er umulig med Bluto på disse modellene:

2011 Mukluk (Aluminum, Blue)
2012 Mukluk 2 (Aluminum, Black/Red)
2012 Mukluk 3 (Aluminum, Blue)
2012/2013 Mukluk Ti (Ti, Brushed Finish)

- The following frames use straight 34mm (1-1/8") headtubes. This type of headtube is not compatible with tapered fork steerers, which makes it impossible to run Bluto on these models.

Mukluk 2013
Den gode nyheten er, at om du har hvilken som helst annen Salsa fatbike-modell enn med disse rammene, kan du Bluto-tilpasse den. Vel og merke ved hjelp av noen ekstra tilpasninger for å få det til å fungere. Følgende modeller kan tilpasses Bluto-dempergaffel med maks 80mm vandring:

2013 Mukluk 2 (Aluminum, White/Green)

2013 Mukluk 3 (Aluminum, Orange)
2013 Mukluk Frame Only  (Aluminum, Black/Purple)

Men før det i det hele tatt lar seg gjøre, må du i følge Salsa-ekspertene sørge for to ting:

Step 1: New Headset
- These frames use a 44mm straight headtube and came spec'd with a ZS44/30 lower headset cup and crown race to fit the stock 1-1/8" straight steerer Enabler fork.  In order to fit a Bluto to these frames, a new EC44 lower headset cup must be purchased and installed in the frame and the matching crown race installed on the Bluto.

Step 2: New Front Hub or Wheel
- These bikes came with a front wheel using a Salsa Enabler hub, which is a 10 x 135mm quick-release hub and is not convertible to the 15 x 150mm thru-axle hub spacing the Bluto uses. Options are to build a new front wheel or re-lace your existing rim onto a new 15 x 150mm thru-axle hub. Salsa has created a front hub compatible with Bluto and it will be available for sale the same time the forks are. 

Mukluk 2014
På følgende modeller kan Bluto-gaffel settes opp med maksimum 100mm vandring, uten å måtte modifisere headsetet:

2014 Mukluk Ti (Titanium, Green/Clear)
2014 Mukluk 2 (Aluminum, Gold)
2014 Mukluk 3 (Aluminum, Red or Matte Black)

- The stock 40mm nominal crown race can be carefully removed from the fork and reused on Bluto. However, one of the following wheel modificiation must be made:

Option 1: End Cap Swap & Wheel Dish
This option is only intended for wheels with Salsa Fat Conversion front hubs and rims with 12.5mm or less spoke hole offset. (NOTE: This includes the stock front wheel.) The Salsa Fat Conversion front hub is convertible from 9 x 135mm quick-release to 15 x 150mm thru-axle by changing the end caps. Salsa will have these end caps available around the same time the fork is. The end cap swap keeps the brake mounting surface aligned properly with Bluto, shifting the hub to the left side of the frame/fork centerline. In order to keep the rim and tire centered in the frame, the wheel must then be re-dished 7.5mm to the drive side. Warning - This option cannot be used for Surly Clown Shoe rims, or any other rim with spoke hole offsets larger than 12.5mm that is laced to a Salsa Fat Conversion front hub. The re-dish yields poor bracing angle of the spokes on the right flange and can result in an unstable wheel.

Option 2: New Hub or Front Wheel
Salsa is offering a 15 x 150mm Fat Conversion front hub compatible with Bluto and it will be available at the same time the forks are. This option is best for people who want to use rims with larger than 12.5mm offset spoke holes (like Surly Clown Shoe), or people who don't want to bother with Option 1 above. This option also results in a better tension-balanced wheel build.

Beargrease 2013
Er du lykkelig eier av en 2013 Beargrease (Aluminum, Black/Blue), men har lyst til å bli enda litt mer lykkeligere, kan også denne tilpasses Bluto-gaffel med maks 80mm vandring. På denne ramma  trenger du ikke modifisere headsetet, men det er likevel noen hensyn du må ta.
- The stock 40mm nominal crown race can be carefully removed from the fork and reused. However, considerations for the front wheel must be made. These bikes came with a front wheel using a Salsa Enabler hub, which is a 10 x 135mm quick-release hub and is not convertible to the 15 x 150mm thru-axle hub spacing the Bluto uses. Options are to build a new front wheel or re-lace your existing rim onto a new 15 x 150mm thru-axle hub. The Salsa Fat Conversion 150mm front hub that is compatible with Bluto will be available for sale the same time the forks are. 

Beargrease 2014
Beargrease karbon-ramme kan tilpasses Bluto med maks vandring 100mm, men kan være litt utfordrende alt ettersom hvilken rammestørrelse det er snakk om, så her bør du lese nøye igjen størrelsespesifikasjonene under.

2014 Beargrease XX1 (Carbon, Green/Yellow)
2014 Beargrease X9 (Carbon, Blue/Purple)

- Carefully review size-specific info. Wheel modification considerations are the same for all sizes.

Small:  Stock lower headset bearing is okay. A special Cane Creek crown race must be used in favor of the stock race in order to slightly lower the crown a few millimeters and provide adequate clearance between the blue compression knob and the downtube.  Without this special crown race, this knob will contact the downtube, and damage to the frame will occur. Salsa Customer Service (support@salsacycles.com) has coordinated to make these races available to owners of small Beargrease frames at a nominal fee through their local Salsa dealer. Wheel considerations must also be made, see below.

Medium: Stock lower headset bearing and crown race should be okay. On every Medium of this model we have checked, the blue compression adjustment knob on the Bluto fork cleared the downtube by 1mm. However, it is possible that due to manufacturing tolerances in both the frame and forks that some MD frame and fork combinations do not clear. If this ends up being the case, the special Cane Creek crown race required for the small can be used on a medium frame with lack of clearance to fix the issue straight away. Wheel considerations must also be made, see below.

Large & X-Large: The stock lower headset bearing and crown race are okay. Downtube clearance on these sizes is adequate. Wheel considerations must be made, see below.

Uansett størrelse på 2014 Beargrease-modellen din, må du også sørge for en av to hjulmodifiseringer før du kan sette igang.

Option 1: End Cap Swap & Wheel Dish
This option is only intended for wheels with Salsa Fat Conversion front hubs and rims with 12.5mm or less spoke hole offset. (This includes the stock front wheel.) The Salsa Fat Conversion front hub is convertible from 15 x 142mm thru-axle to 15 x 150mm thru-axle by changing the end caps. Salsa will have these end caps available around the same time the fork is. The end cap swap keeps the brake-mounting surface aligned properly with Bluto, shifting the hub to the left side of the frame/fork centerline. In order to keep the rim and tire centered in the frame, the wheel must then be re-dished 7.5mm to the drive side.  Warning - This option cannot be used for Surly Clown Shoe rims, or any other rim with spoke hole offsets larger than 12.5mm that is laced to a Salsa Fat Conversion front hub. The re-dish yields poor bracing angle of the spokes on the right flange and can result in an unstable wheel.

Option 2: New Hub or Front Wheel
Salsa is offering a 15 x 150mm Fat Conversion front hub compatible with Bluto and it will be available the same time the forks are. This option is best for people who want to use rims with larger than 12.5mm offset spoke holes (like Surly Clown Shoe), or people who don't want to bother with Option 1 above.

Se på tabellen under for oversikt over informasjonen beskrevet hittil, og husk at det som ved alle andre oppgraderinger, oppfordres til at du tar kontakt med din lokale Salsa-forhandler for å få Bluto-tilpasset Salsa-fatbiken din. De har som regel kunnskapen, ferdighetene og verktøyet til å utføre dette på riktig måte.
